SILVACO TCAD Implementation of Dual Junction Quantum Well Solar Cell

Abstract

Inserting Quantum wells into solar cells has been a novel technique for producing high efficiency third generation solar cells. Here we present a Multi-Quantum-well Dual-Junction GaAs/GaSb solar cell which is simulated using a numerical semiconductor device simulator (Silvaco TCAD) where number of wells is varied to see its effect on single as well as dual junction solar cell and a maximum of 30% efficiency is achieved.
