In a multi-junction solar cell, due to the existence of multiple junctions, generation of photo-generated minority charge carrier increases that improves the efficiency of the device with reference to reduction in recombination current. In this paper, authors have analyzed the performance improvement in a multi-junction solar cell with simulation results in R-soft. Simulation results show maximum efficiency 27.59% for multi-junction solar cell whereas for single junction solar cell it is 11.0259%. In the multi-junction solar cell, open circuit voltage \( V_{oc} \) and short circuit current \( I_{sc} \) are also compared to a single junction solar cell.
