Abstract

Solar cells based on multiple quantum wells have attracted a great deal of attention in recent years. Due to the superior radiative nature, the output voltage is expected to be more ideal over solar cells made of bulk materials. In this research, based on the effective map analysis technique we proposed previously to ensure a fair comparison, we investigate quantum well solar cells and their bulk counterpart in terms of radiative efficiency, and compare several significant properties at a consistent absorption edge wavelength. This provides a good insight into the factors which limit the efficiency of quantum well solar cells.
