Abstract :
Techniques of dye-sensitized nanocrystalline solar cells(DSSCs) having a conversion efficiency of AM 1.5G solar light to electric power over 11% are reported. In this paper,the fundamental structure and the principle of DSSCs are introduced and the development of key components, including nanoporous semiconductor films, dye sensitizers, electrolyte and counter electrode in DSSCs are reviewed in detail. It is also an interesting aspect where collaboration among different fields of scientists is important to develop the solar cells and to elucidate the mechanism of DSSCs. Further increase of the efficiency is gained by the interdisciplinary research.
