Solar cells that use chemically synthesized SnSe nanosheets as the light absorption layer were investigated. SnSe nanosheets are expected as a material for tandem solar cells that can be produced by the coating method. A power conversion efficiency (PCE) of 1.07% was obtained using a light absorption layer in which SnSe nanosheets and PEDOT: PSS were mixed at a volume ratio of 1: 75. The PCE is the highest ever for a similar solar cell obtained using chemically synthesized SnSe nanosheets.
