Abstract

The influence of spontaneous and strain-induced piezoelectric polarizations on the photovoltaic characteristics of an Al 0.14Ga 0.86N/In 0.21Ga 0.79N superlattice (SL) solar cell is numerically investigated. The simulation results show that, compared with the conventional p-i-n structure, the Al 0.14Ga 0.86N/In 0.21Ga 0.79N SL solar cell has better photovoltaic characteristics and is less sensitive to the effect of internal polarization. Therefore, the use of an SL structure in the III-nitride solar cells is advantageous if both the polarization effect and the crystal quality are of major concern.
