Abstract

Wafer bonded, silicon based multi-junction solar cells are a promising approach for achieving high efficiencies with relatively low cost. Due to poor long wavelength light absorption in silicon, however, the cell efficiency is limited by current mismatch. In this work, for the first time, an external surface texturing is attached onto a GaInP/GaAs//Si wafer bonded solar cell using Polydimethylsiloxane layers with surface geometries replicated from various pyramidally-textured silicon wafers. With the improved light trapping, the AM1.5G spectrum weighted average reflected current density for the cell is reduced by 3.72 mA/cm2, within which 1.81 mA/cm2 is reduced at long wavelength range that can boost the current generation in silicon bottom cell.
