| Outline of Final Research Achievements |
By combining the optical microscopy including near-filed optical microscopy and femtosecond time-resolved transient absorption spectroscopy, I have performed the development of the transient absorption absorption imaging spectrometer with high spatial resolution, and I am mow in the phase of its appplication to real materials and devices. In particular, I have achieved the development of the high-sensitive system which can detect very weak transient absorption signal (< 5×10-5). By utilizing such high sensitivity, I have succeeded in performing the femtosecond time-resolved transient absorption measurments of the organic thin-film solar cell undeer very low excitation density. Based on the result, I have calrified the details of charge generation processes in the organic thin-film solar cell.
