| Outline of Final Research Achievements |
We tried to evaluate the two-step excitation phenomenon using two lights of different wavelengths in inter-band solar cells by using visible-light photo-electron spectroscopy developed by our group. In this method, the energy distribution of electron in conduction band can be evaluated. Firstly, we developed the system for two
light irradiation. Using this system, the spectra of visible-light photo-electron spectroscopy were acquired. The intensity of two light excitation was stronger than that of single light excitation.
