Mesoporous Structure Solar Cell with Siloxane Barrier

摘要

A method is provided for forming a mesoporous-structured solar cell with a silane or siloxane barrier. The method forms a transparent conductive electrode overlying a transparent substrate. A non-mesoporous layer of a first metal oxide overlies the transparent conductive electrode, with a mesoporous layer of a second metal oxide overlying the non-mesoporous layer of first metal oxide. An aminoalkoxysilane layer overlies the mesoporous layer of second metal oxide. Over the aminoalkoxysilane layer is deposited a semiconductor absorber layer comprising organic and inorganic components. Using the aminoalkoxysilane linker, the mesoporous layer of second metal oxide is linked to the semiconductor absorber layer. A hole-transport material (HTM) layer is formed overlying the semiconductor absorber layer, and a metal electrode overlies the HTM layer. A mesoporous-structured solar cell with a silane or siloxane barrier is also provided.
