Towards high-efficiency cztse solar cells through the optimization of the p-MoSe2 interfacial layer [PDF]

, 2021
This paper reports the impact of the p-MoSe2 transition metal dichalcogenide as an interfacial layer between the CZTSe absorber and Mo back contact in the CZTSe solar cells. Here, the solar cell capacitance simulator (SCAPS-1D) is employed.

Reactive Mechanism of Cu2ZnSnSe4 Thin Films Prepared by Reactive Annealing of the Cu/Zn Metal Layer in a SnSex + Se Atmosphere

Crystals, 2018
Cu2ZnSnSe4 (CZTSe) thin films were prepared by a two-step process with the electrodeposition of a Cu/Zn metallic stack precursor followed by a reactive anneal under a Se + Sn containing atmosphere. We investigate the effect of the Sex and SnSex (x = 1,2)
