Thin film solar panels is a new type of photovoltaic device to alleviate the energy crisis. thin film solar cells can be used in the low price of different materials such as ceramic, graphite, metal when the substrate to produce, the form can produce voltage it takes only a few microns thin film thickness, at present the highest conversion efficiency can reach 13%.portable solar power in addition to the plane, also because have flexible nonplanar structure can be made into its application scope is big, can be combined with buildings or become a part of the building, application is very broad.
Historical of solar power panels
With coal, oil, natural gas and other energy sources increasingly depleted and environmental pollution increasing, there is an urgent need to find clean and renewable new energy sources.The application of solar energy, as the earth's infinite renewable and pollution-free energy, has attracted increasing attention.At present, the commercialized crystalline silicon solar cells have the highest photoelectric conversion efficiency, but due to the limitation of material purity and preparation technology, the cost is high, so it is difficult to improve the conversion efficiency or reduce the cost.Thin film solar cells, which can convert light to electricity with only a few inches of thickness, are ideal materials for reducing costs and improving photon circulation.
Thin film solar technology
Thin film solar cell can be used in the low price of glass, plastic, ceramic, graphite, different materials as substrates to manufacturing, such as sheet metal forming can produce voltage it takes only a few microns thin film thickness, thus in the same area by light can significantly reduce the silicon wafer solar cells under the amount of raw material (thickness can be lower than silicon wafer solar cells more than 90%), the current lab conversion efficiency has reached more than 20%, the highest scale production stable highest efficiency by about 13%.Thin film solar cells in addition to the plane, also because have flexible nonplanar structure can be made into its application scope is big, can be combined with buildings or become a part of the building, on the thin film solar cell manufacturing, can use all kinds of sedimentary deposition technology, layer upon layer to p - type or n - type material, common amorphous silicon thin film solar cells are, CuInSe2 (CIS), CuInGaSe2 (CIGS), and CdTe.And so on.
