| Research Abstract |
This study has aimed at constructing a novel solid-state photovoltaic device that comprises a junction of oxide semiconductor, ionic conductor, electro-conductive olymer, and carbon material in which one of the heterogeneous interfaces formed is loaded with a light-absorbing material that causes photo-excited electron transfer and light energy conversion with high efficiency. Two types of devices based on the above concept have been constructed ; one is composed of organic dye (light absorber), TiO_2 semiconductor, ionic liquid, and polyaniline/carbon composite and the other composed of organo lead halide type nano-crystal (light absorber), TiO_2 semiconductor, and ionic electrolyte. The former yielded an energy conversion efficiency with respect to the solar spectrum of 4.1% and the latter yielded 3.8%.
