In this presentation, we will introduce photo-assisted Kelvin probe force microscopy that realizes photovoltaic measurements and photothermal-mode atomic force microscopy that enables us to investigate photo-induced thermal expansion by showing the examples of their application to the evaluation of microcrystalline Cu(In,Ga)(S,Se)₂ solar cell materials.
