Flat glass is an integral component of many solar energy technologies, including solar thermal collectors, photo voltaic modules and concentrated solar power plants. The solar energy market for flat glass is one of high added-value glass products and a strong driver for innovation. However, despite Europe's technological lead, a crumbling European market and unfair trade practices in the entire value chain have severely hit Europe's production. Glass is designed to optimise solar energy conversion while providing long term protection against external conditions. Extra clear glass, with low iron oxide content is typically used in solar applications. Either float or patterned, low iron glass may be coated with an anti-reflecting coating to further increase performance. Transparent conductive coating can also be used as an electrical contact in some photo voltaic technologies allowing the light through to the photovoltaic material while conducting the general electricity out of the modules. Glass may also be toughened to increase strength and durability.Glass in solar thermal applicationsSolar thermal collectors are intended to collect heat - as opposed to photo voltaic panels which convert sunlight into electrical power. The collected solar heat can be used to supply hot water or heat ex changers, for domestic or industrial applications.There are various kinds of solar thermal collectors but most require a flat glass cover, or glazing, which serves not only to protect the panel while letting the sunlight through but also to prevent cooling of the panel from exposure to cold air.Glass in photovoltaic applicationsPhoto voltaic technologies are used to convert solar energy directly into electricity. There are many different technologies available to suit various requirements, from domestic systems to utility scale. Photo voltaic panels come in various shapes and colors offering flexibility for design integration and building integrated applications (BIPV).The most common photo voltaic technology is based on crystalline silicon solar cells. In this application glass acts as a protective outer layer, while transmitting the solar light to the photo voltaic cells interconnected underneath.Other photo voltaic technologies include thin film where solar cells are deposited as a sequence of thin films on glass. In these technologies, transparent conductive coated glass can be used as the front glass upon which the films are grown. The conductive coating not only allows light through to the photo active films, but also conducts the generated electricity out of the modules.Glass and mirrors in concentrated solar power SystemsConcentrated Solar Power (CSP) systems are used to produce electricity from the sun at utility scale. These systems are mainly used in regions with high levels of solar irradiance. CSP systems use lenses or mirrors to concentrate a large amount of sunlight onto a central receiver, thereby producing electricity either by concentrating the sunlight onto a high performance photo voltaic cell or by heating a transfer fluid to supply heat to a conventional thermodynamic power plant. For CSP systems, extra clear glass and mirrored glass are used to redirect accurately the maximum amounts of light towards the focal point.

What is photovoltaic effect? Photovoltaic effect is defined as the phenomenon in which the incidence of light upon the junction of two dissimilar materials, as a metal and a semiconductor, induces the generation of an electromotive force. Simply put, photovoltaic effect is the creation of electric current in a material upon exposure to light and is an electro-chemical phenomenon. Having no moving parts – like turbines etc. which are typical of other forms of electricity production- is a unique advantage of photovoltaic power generation. The most common material used to make solar PV cells is Silicon because it shares some of the properties of metals and some of those of an electrical insulator. Photovoltaic cells consist of a positive laver and a negative layer of this material. Let’s take a closer look at what happens when the sun shines onto a solar cell. Sunlight consists of little particles of energy called photons. When this energy in sunlight strikes the silicon based solar cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current -- that is, electricity.

This glass is used for multi and mono crystalline solar photovoltaic modules. The content of iron oxide is significantly lower than in normal flat glass, which gives it a distinctive, nearly colourless appearance particularly when seen from the edge, and makes it a high solar energy transmitting glass. The textured surface helps to diffuse the light and inhibits the reflection of a part of the solar energy back into the atmosphere as compared to a polished surface, thus enhancing solar energy transmission.

solar control glass Solar energy can be pleasant and utilisable in many cases, but especially in buildings, it represents a major source of overheating and unpleasant glare. Solar control glass, usually either body-tinted (absorbing) or coated (reflecting), is used to reduce unwanted solar radiant light and heat energy transmitted through glass.

Our Solar Photovoltaic Cell works on the principle of conversion of sunlight into electricity. This is achieved either by photovoltaics (solar panels) or by thermal concentrating devices. Our Solar Photovoltaic Cell, with a typical lifetime of 20 to 30 years, generates significantly more energy over a lifetime than the energy expended in producing it. Overview Of Solar Cell Types Solar cell types are broadly grouped into two categories – bulk (or wafer-based silicon) and thin film cells. All solar cells require a light absorbing material to absorb photons and generate electrons via the photovoltaic effect. Most solar cells are designed to absorb the wavelengths of solar light that reach the earth surface. Some solar cells are optimized for light absorption beyond Earth's atmosphere, for use in "outer space"... Solar panels are normally fabricated using either silicon or thin-film cell technology. Many of the types of solar cells available are made from bulk materials that are then cut into wafers. Other materials are configured as thin-films that are bonded to supporting substrates. Nanocrystals are also used. These are placed as quantum dots (electron-confined nanoparticles) embedded in a supporting matrix. Silicon is still the only substance, which is well researched in both bulk and thin-film cell technology. There are new alternatives to silicon cells being developed. Proprietary nanoparticle silicon printing will offer many features that conventional silicon cannot. It is the most promising of the new technologies. Nanoparticle silicon can be printed reel-to-reel on stainless steel or other high temperature substrates. Most of the work on the next generation of photovoltaic is directed at printing onto low cost flexible polymer film and ultimately on common materials. The main technologies looking promising are currently CIGS, CdTe, DSSC, and organic photovoltaics.

Material Monocrystalline SiliconPolycrystalline SiliconAmorphous Silicon Photovoltaics: Solar Electricity and Solar Cells in Theory and Practice The word Photovoltaic is a combination of the Greek word for Light and the name of the physicist Allesandro Volta. It identifies the direct conversion of sunlight into energy by means of solar cells. The conversion process is based on the photoelectric effect discovered by Alexander Bequerel in 1839. The photoelectric effect describes the release of positive and negative charge carriers in a solid state when light strikes its surface. How Does a Solar Cell Work? Solar cells are composed of various semiconducting materials. Semiconductors are materials, which become electrically conductive when supplied with light or heat, but which operate as insulators at low temperatures. Over 95% of all the solar cells produced worldwide are composed of the semiconductor material Silicon (Si). As the second most abundant element in earth`s crust, silicon has the advantage, of being available in sufficient quantities, and additionally processing the material does not burden the environment. To produce a solar cell, the semiconductor is contaminated or "doped". "Doping" is the intentional introduction of chemical elements, with which one can obtain a surplus of either positive charge carriers (p-conducting semiconductor layer) or negative charge carriers (n-conducting semiconductor layer) from the semiconductor material. If two differently contaminated semiconductor layers are combined, then a so-called p-n-junction results on the boundary of the layers. At this junction, an interior electric field is built up which leads to the separation of the charge carriers that are released by light. Through metal contacts, an electric charge can be tapped. If the outer circuit is closed, meaning a consumer is connected, then direct current flows. Silicon cells are approximately 10 cm by 10 cm large (recently also 15 cm by 15 cm). A transparent anti-reflection film protects the cell and decreases reflective loss on the cell surface. The usable voltage from solar cells depends on the semiconductor material. In silicon it amounts to approximately 0.5 V. Terminal voltage is only weakly dependent on light radiation, while the current intensity increases with higher luminosity. A 100 cm² silicon cell, for example, reaches a maximum current intensity of approximately 2 A when radiated by 1000 W/m². The output (product of electricity and voltage) of a solar cell is temperature dependent. Higher cell temperatures lead to lower output, and hence to lower efficiency. The level of efficiency indicates how much of the radiated quantity of light is converted into useable electrical energy. Different Cell Types One can distinguish three cell types according to the type of crystal: monocrystalline, polycrystalline and amorphous. To produce a monocrystalline silicon cell, absolutely pure semiconducting material is necessary. Monocrystalline rods are extracted from melted silicon and then sawed into thin plates. This production process guarantees a relatively high level of efficiency. The production of polycrystalline cells is more cost-efficient. In this process, liquid silicon is poured into blocks that are subsequently sawed into plates. During solidification of the material, crystal structures of varying sizes are formed, at whose borders defects emerge. As a result of this crystal defect, the solar cell is less efficient. If a silicon film is deposited on glass or another substrate material, this is a so-called amorphous or thin layer cell. The layer thickness amounts to less than 1µm (thickness of a human hair: 50-100 µm), so the production costs are lower due to the low material costs. However, the efficiency of amorphous cells is much lower than that of the other two cell types. Because of this, they are primarily used in low power equipment (watches, pocket calculators) or as facade elements. Level of efficiency in % Lab approx. 24approx. 18approx. 13 Level of efficiency in % Production 14 to1713 to155 to7 From the Cell to the Module In order to make the appropriate voltages and outputs available for different applications, single solar cells are interconnected to form larger units. Cells connected in series have a higher voltage, while those connected in parallel produce more electric current. The interconnected solar cells are usually embedded in transparent Ethyl-Vinyl-Acetate, fitted with an aluminum or stainless steel frame and covered with transparent glass on the front side. The typical power ratings of such solar modules are between 10 Wpeak and 100 Wpeak. The characteristic data refer to the standard test conditions of 1000 W/m² solar radiation at a cell temperature of 25° Celsius. The manufacturer's standard warranty of ten or more years is quite long and shows the high quality standards and life expectancy of today's products. In addition to optimizing the production processes, work is also being done to increase the level of efficiency, in order to lower the costs of solar cells. However, different loss mechanisms are setting limits on these plans. Basically, the different semiconductor materials or combinations are suited only for specific spectral ranges. Therefore a specific portion of the radiant energy cannot be used, because the light quanta (photons) do not have enough energy to "activate" the charge carriers. On the other hand, a certain amount of surplus photon energy is transformed into heat rather than into electrical energy. In addition to that, there are optical losses, such as the shadowing of the cell surface through contact with the glass surface or reflection of incoming rays on the cell surface. Other loss mechanisms are electrical resistance losses in the semiconductor and the connecting cable. The disrupting influence of material contamination, surface effects and crystal defects, however, are also significant. Single loss mechanisms (photons with too little energy are not absorbed, surplus photon energy is transformed into heat) cannot be further improved because of inherent physical limits imposed by the materials themselves. This leads to a theoretical maximum level of efficiency, i.e. approximately 28% for crystal silicon.
