摘　　要：非化学计量比氧化钼即MoO_(x)是一种n型半导体材料,能够取代硅异质结太阳电池中的p型非晶硅,输运n型晶体硅中的光生空穴。基于MoO_(x)空穴选择性接触的硅异质结太阳电池已经取得了高达23.5%的效率,并且有望降低生产成本。总结了基于MoO_(x)空穴选择性接触的硅异质结太阳电池的研究进展,综述了电池的空穴输运机制,为优化光伏器件性能和设计新型太阳电池提供一定借鉴作用。Non-stoichiometric molybdenum oxide is an n-type semiconductor material,which can replace p-type amorphous silicon in silicon heterojunction(SHJ)solar cells and transport photogenerated holes in n-type crystalline silicon.The efficiency of silicon heterojunction solar cells with MoO_(x)-based hole selective contact has been up to 23.5%,and it is expected to reduce the production cost while achieving high efficiency.In this paper,the research progress of silicon heterojunction solar cells with MoO_(x)-based hole selective contact was summarized,and the hole transport mechanism of solar cells was reviewed.This work provides a reference for optimizing device performance and designing new solar cells.
