Abstract :
Efficiency of n-Si1-xGex/p-Si heterojunction solar cell with different Ge-content is studied in this paper. Carrier confinement at the heterointerface between Si and SiGe is considered in this study. A nonlinear variation of overall efficiency of Si/SiGe solar cell with Ge-content (x) is obtained. Efficiency initially increases with increase in x and after a maximum value it decreases. Efficiency without considering the effect of carrier confinement is also studied.
