对石墨烯/半导体异质结太阳能电池进行了理论和实验研究。通过控制石墨烯层数、调整石墨烯功函数和添加石墨烯薄膜，可以获得最大的理论转换效率为9.2%。根据理论优化方案，制备了具有改性石墨烯膜和硅柱阵列的肖特基结太阳能电池，发现其转换效率高达7.7%。
Theoretical and experimental studies have been performed to simulate and optimize graphene/semiconductor heterojunction solar cells. By controlling graphene layer number, tuning graphene work function and adding an antireflection film, a maximal theoretical conversion efficiency of ∼9.2% could be achieved. Following the theoretical optimization proposal, the Schottky junction solar cells with modified graphene films and silicon pillar arrays were fabricated and were found to give a conversion efficiency of up to 7.7%.
