摘　　要：近年来有机-无机杂化钙钛矿太阳能电池(perovskite solar cells, PSCs)因具有光电转换效率高、制备工艺简单等优点而受到广泛关注.空穴传输层(hole transport layer, HTL)的选择及其优化对器件的性能至关重要.氧化镍(NiO_(x)) HTL具有化学稳定性好、空穴迁移率高、制备方法简单等特点,在PSCs中得到了广泛应用.本综述从NiO_(x) HTL在平面PSCs中的应用入手,系统介绍了通过掺杂和表面修饰法实现对NiO_(x) HTL薄膜的结构和光电性能的改性,并从能级匹配、空穴迁移率及结晶性等多个角度详细评述了NiO_(x)改性对PSCs光电转换效率、填充因子、开路电压、短路电流和稳定性的影响规律,最后对于NiO_(x)平面PSCs的未来进行了展望.In recent years,organic-inorganic hybrid perovskite solar cells(PSCs)have attracted wide attention due to their high photoelectric conversion efficiency and simple preparation process.Hole transport layer(HTL)is one of the most critical components in PSCs.As a kind of inorganic HTL material,nickel oxide(NiO_(x))has been widely used in perovskite solar cells because of its excellent advantages,such as outstanding chemical stability,high carrier mobility,simple methods for its preparation,etc.In this paper,the applications of NiO_(x) HTL in planar PSCs are systematically summarized from the aspects of the improvment of its structure and photoelectric properties by doping and interface modification.The reasons for affecting the device performances,i.e.fill factor,open-circuit voltage,short-circuit current,photoelectric conversion efficiency,and stability are emphatically analyzed from several aspects,such as energy level matching,hole mobility and crystallinity.In addition,the future development directions of the planar PSCs are prospected.
