spray pyrolysis, multijunction, ZnO, absorption coefficient, conversion efficiencyAbstract
Photovoltaic cells made of silicon and germanium, which are currently in use, eliminate fuel transport and storage issues but are hindered by the current cost of the materials and fabrication. The spray pyrolysis technique was employed to fabricate and characterize multijunction
solar cell due to its simplicity, reproducibility, and economic factors. Current-voltage characteristics indicated an increase in current and efficiency when a current collection grid was used. The fabricated tandem solar cell showed an open voltage
of 720 mV, a short circuit
of 3.25 mA, a fill factor FF of 0.68, a maximum power
of 1.61
, and a conversion efficiency
of 1.57%. Based on the findings, it can be concluded that the fabrication process and characterization techniques employed in this study resulted in the successful development of a
tandem solar cell with enhanced performance. The use of ZnO-Mg films contributed to improved absorption coefficient and energy band gap, leading to higher efficiency.
