Solar energy is inexhaustible human renewable energy. Is also a clean energy, does not produce any environmental pollution. Among the effective use of solar energy; the use of solar energy photovoltaic is the fastest growing in recent years, the most dynamic area of research, is one of the most watched one of the items. To this end, it is research and development of solar cells. Production of solar cells are mainly based on semiconductor materials, its working principle is the use of photovoltaic materials, occurred after the photoelectric absorption of light energy in the conversion reaction, according to the different materials used in solar cells can be divided into: 1, silicon solar cell; 2, with inorganic salts such as gallium arsenide III-V compounds, cadmium sulfide, Inspiron 600m battery copper indium selenium compounds such as multi-material cells; 3, functional polymer materials can be prepared by sun cells; 4, nano-crystalline solar cells. Regardless of what material to produce batteries for solar cell materials, general requirements are: 1, band gap semiconductor materials can not be too wide; ② have a high photoelectric conversion efficiency of: 3, the material itself will not cause environmental pollution; 4, material suitable for mass production and the material properties and stability. Based on the above aspects to consider is the best silicon solar cell material, which is silicon-based solar cells to the main reason. However, with the continuous development of new materials and related technologies, in other village-based solar cell materials have shown more and more attractive prospect. This paper briefly reviews the types of solar cells and its research status, and discussed the development of solar cells and trends.
