英文摘要
We have applied the photo-assisted KFM and the AFM photo-thermal spectroscopy, which we have originally developed, as well as the scanning tunneling spectroscopy on multi- and micro-crystalline solar cell materials in order to investigate their various properties very locally. As a result, we successfully found some specific features of the band profile around the grain boundary, the minority carrier dynamics, such as diffusion ength, lifetime and mobility, with their spatial distribution, and the recombination process of photo-excited carriers.
