Abstract: Although organic materials have been widely utilized for the fabrications of organic solar cells as they are inexpensive, easily prepared and compatible with substrates, the development of organic solar cells has been hindered mainly due to their low carrier mobility, poor stability and unsatisfactory matching with the solar spectrum. On the other hand, inorganic materials have high electron mobility and absorption spectra matching with the solar spectrum. Therefore the power conversion efficiency of organic solar cells is still not competitive with those of inorganic solar cells. If the advantages of both organic and inorganic materials could be combined, the performance of organic solar cells would be enhanced. At present, some progresses have been made in inorganicorganic hybird solar cells. Usually, the inorganic materials were used in the acceptor layer, cathode buffer layer and anode buffer layer to improve the energy conversion efficiency of organic solar cells. In this article we discussed the applications of some inorganic materials in organic solar cells and the recent research progresses as well as the perspectives in this field.

Key words: Organic solar cells, Hybrid system, Inorganic materials, Organic materials, Energy conversion efficiency
