The latest Research Progress of three kinds of thin Film Solar cells

Eutectic photovoltaic technology : With the decrease of non - renewable energy , the environmental pollution becomes more serious , people gradually increase the demand for renewable energy . Solar energy belongs to a kind of renewable energy , has the advantages of rich resources and clean environment , which makes the research of solar cell become the focus . The thin film solar cell is mainly composed of silicon base , compound and dye - sensitized solar cell . 1 . The silicon base thin film solar cell silicon base film solar cell can be divided into amorphous silicon , polycrystalline silicon and microcrystalline silicon thin film solar cell according to the material , wherein the amorphous silicon thin film solar cell is developed by using glass , stainless steel and the like as a substrate , so it is considered to be the best battery with the best environmental protection performance . The amorphous silicon thin film solar cell has the characteristics of light weight , good light absorption , high temperature resistance and the like , wherein , the solar cell with the efficiency of 4.6 percent is prepared by the HWCVD method , and the high - efficiency solar cell with the area of 1.4 meters * 1.1 meters and the efficiency of 8 percent is developed . The polycrystalline silicon thin - film solar cell not only has the advantages of high efficiency and stability of the crystalline silicon solar cell , but also has the advantages of less material consumption and low production cost . The microcrystalline silicon thin - film solar cell has the characteristics of compatibility with amorphous silicon thin film cell , wide spectral response and no light - induced degradation . In 1994 , the microcrystalline silicon cell with a thickness of about 1.7 μm and an area of about 0.25cm is developed by using the technology of vHF - PECVD in 1994 . The efficiency is up to 6.3 % . However , the deposition rate of microcrystalline silicon thin - film solar cell is low , so it needs to be further studied . A thin - film solar cell prepared by the compound has the characteristics of large light absorption coefficient , good anti - radiation performance and small temperature coefficient . The compound film solar cell mainly comprises gallium arsenide , cadmium telluride and copper indium - selenium thin film solar cells . In 1991 , M . Gr ? tzel ' s research team developed a dye - sensitized solar cell with a efficiency of 7.1 % . In 2005 , M . Gr ? tzel et al . developed a dye - sensitized solar cell with a efficiency of 7.1 % . In 2005 , M . Gr ? tzel et al . developed a dye - sensitized solar cell with an efficiency of 7.1 % . IV . In conclusion , the above three thin - film solar cells have their own characteristics , believe that with the extensive development of the research , these thin - film solar cells will have a new technological breakthrough in the near future , thus obtaining higher conversion efficiency and being widely applied to the daily life of people , reducing environmental pollution and reducing the consumption of non - renewable energy . Jiangxi eutectic PV Technology Co . , Ltd . was established in 2009 . As a high - tech enterprise , eutectic PV has been devoted to research and development , manufacture , sales and technical support of crystalline silicon solar cells , components , photovoltaic applications and related solar products .
