Abstract—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.
