Simulation study of monolithic MoSe2/CIGS tandem solar cells

Abstract This article aims to study MoSe 2 /CIGS tandem solar cells employing SCAPS-1D computational package based on ant colony algorithm. The simulation of Monolithic MoSe 2 /CIGS tandem solar cells has been implemented successfully by employing the Matlab/Simulink. The power output of the Monolithic MoSe 2 /CIGS tandem modules increases by the solar irradiations during the first few days of operation. The J–V characteristic and average daily energy production throughout the year has been calculated. The results show 80.71% FF and 19.29% efficiency of the solar cell. The other parameter for the MoSe 2 /CIGS tandem solar cell are V oc = 0.62 V; J sc = 38.69 mA/cm 2 .
