Outline of Final Research Achievements

We examined the possibility to fabricate the translucent and dry-type solar cells by the molecular precursor method which is one of the wet processes for thin film formation of metal oxides. The translucent and dry-type solar cells by combination with a p-type Cu2O thin film were fabricated on AZO pre-coated substrate by the wet process. The structure of the solar cell was AZO/n-TiO2/ p-Cu2O. When the visible-light responsive titania was fabricated between the AZO and Cu2O, the solar cell provided the power conversion efficiency (η) of 0.001 %. Thus, it was elucidated that the present molecular precursor method has a possibility to be useful for the facile fabrication of the Vis-responsive dry solar-cell on large-area substrates.
