Abstract


In this work an all-InGaN-based p-i-n structured quantum well solar cell (QWSC) has been implemented in Silvaco TACD environment. Use of same material for different layers reduces the lattice mismatch for which recombination loss is reduced and also, insertion of low-bandgap quantum wells (QWs) enahnces the aborption of long-wavelength light for which photogenerated current is increased, both results in the increase of the conversion efficiency of the proposed solar cell. Simulation results reveal that a 20-layer all-InGaN QWSC has a promising conversion efficiency of 36.669%.
