The results show that for collectors of the same kind, their selectivity is in linear relationship with HOMO energy and can be predicted well. For collectors of different kinds, it can be concluded from shape of HOMO and atomic HOMO density that the selectivity of ethoxycarbonyl thionocarbamates is better than the one of xanthogen formates.

结果表明：对于同种类型的捕收剂，其选择性与HOMO能量呈线性关系，依据HOMO能量能较准确地预测这两种捕收剂的选择性能；对于不同种类的捕收剂，通过对HOMO形状以及组成原子的HOMO密度的讨论可知，乙氧羰基硫氨酯类捕收剂的选择性能要比黄原酸甲酸酯类捕收剂的强。

The optimized device process of p-n Alo.85Gao.15As/GaAs solar cells have been investigated.
