Research Abstract |
In intermediate-band solar cells, electrons are efficiently excited via the intermediate band by using low energy photons to achieve high conversion efficiency. Mini-bands due to superlattice is a candidate of the intermediate-band. In this study, we measured the energy spectra of electrons excited by visible-light in the mini-bands of superlattice solar cells. Firstly we established the equipment that consists of angle-resolved photo-emission electron spectroscopy, NEA preparation chamber and Ti-Sapphire laser. Next, we successfully measured the energy dispersion of the mini-bands due to superlattice structure.
