摘要：
Using simulations, we have identify the major factors controlling the conversion efficiency of single-junction n-GaN/i-InxGa1-xN/p-GaN solar cells, including absorptivity of solar radiation, heterostructure polarity, composition of the InGaN active layer, and non-radiative life-times of generated electrons and holes. The interplay of these factors, their hierarchy, and the possible effect of stress relaxation in InGaN on the conversion efficiency are discussed in terms of modeling.
