Research on new technologies of photoelectric conversion efficiency in solar cell

The characteristics of the solar energy and three conversion mode of solar energy including photovoltaic conversion, solar thermal conversion, and photochemical conversion are represented in this paper. On this basis, the materials used in solar cell, as well as the working principle of solar cells, the factors of low convert efficiency of solar cells and the two major bottlenecks encountered in the solar application are analyzed. The idea that spontaneous arrangement of compound organic molecules is achieved by changing the molecular arrangement structure of the organic thin-film solar is put forward. The new structure of liquid crystal layer come into being accordingly so that the electron donor and the receptor molecules of the mixture are separated, and the contacting area between them is enlarged. So the efficiency solar photovoltaic is improved. The research and development of this new technology can solve the technical problem of the low conversion efficiency of solar cell, and open up an effective way to improve the conversion efficiency of solar cells. At last,the prospect of solar photovoltaic technology, solar energy exploit technology and the development of industry is offered in the article.
