An effective BSF is a key structural element for an efficient solar cell, either in a multi-junction or in a single-junction device. In this paper, two important materials AlGaAs and InAlGaP with their varied thickness (i.e. 0.05–1.0) μm both for top BSF and bottom BSF cells are investigated using the computational numerical modeling TCAD tool Silvaco ATLAS. It has been found that under the current matching condition with the relatively thinner (30 nm) top BSF layer and the thicker (1,000 nm) bottom BSF layer, the cell exhibit an overall enhancement of short-circuit current density Jsc and open circuit voltage Voc thereby improving the overall efficiency of the cell.
