Preparation and Characteristics of MoSe2 Interlayer in Bifacial Cu(In,Ga)Se2 Solar Cells

MoSe2 thin films were formed simply by the selenization of Mo on bare soda lime glass substrate and glass coated with ZnO:Ga. Preliminarily, the structural property of MoSe2 was studied on bare soda lime glass with X-ray diffraction and Raman spectra. Furthermore, the electrical property of MoSe2 was discussed as the interlayer between the Cu(In,Ga)Se2 /ZnO:Ga double layers. Finally, bifacial solar cells with MoSe2 interlayer were illustrated with current-voltage curve and quantum efficiency.
