In order to improve the efficiency of crystalline silicon solar cells, the factors that deteriorated the conversion efficiency were evaluated using hard X-ray photoelectron spectroscopy (HAXPES). In particular, evaluation of characteristic deterioration factors related to transparent conductive films used in SHJ solar cells. New carrier selective contact materials such as titanium oxide (TiOx) and transition metal dicalgogenide (TMD), which is a two-dimensional layered material.
