| Outline of Final Research Achievements |
Photo-assisted nanoprobe methods such as photo-assisted Kelvin probe force microscopy (P-KFM) and photothermal mode atomic force microscopy (PT-AFM) have been developed and improved. By means of them, in addition, photo-induced carrier dynamics, especially their recombination property, in solar cells consisting of multinary compound semiconductor like Cu(In,Ga)(S,Se)2 have been investigated. Furthermore, the electrostatic force microscopy with multi-frequency bias modulation method which becomes a base of optical capacitance AFM (PCap-AFM) has been developed, and its validity has been confirmed through actual measurements on similar solar cells.
