中文摘要:
      金属卤化物钙钛矿材料的太阳能电池由于其成本低廉,光电性能优异,在过去的11年中取得了巨大的进展。然而,在钙钛矿太阳能电池中存在着大量的有害缺陷,如钙钛矿结构内部存在间隙、空位和杂质缺陷,以及钙钛矿成膜时由于其在晶界和晶面上存在悬空键导致的大量的晶界、界面缺陷。这些有害缺陷严重影响载流子输运,阻碍了钙钛矿太阳能电池能量转换效率的进一步提高。近年来通过钝化钙钛矿太阳能电池中的缺陷提高钙钛矿太阳能电池的光电性能取得了巨大的进展。文中根据最新的研究成果总结了合适的钝化策略钝化电池中的缺陷,通过对电池中缺陷的钝化提高了钙钛矿太阳能电池的效率和稳定性。
英文摘要:
      In the past eleven years, solar cells based on metal halide perovskite have made great progress due to their low cost and excellent photoelectric properties. However, there are a lot of harmful defects in the perovskite solar cells, such as gaps, vacancies and impurities in the perovskite structure. In addition, during the film formation of perovskite, a large number of grain boundaries and interface defects are caused by suspended bonds on the grain boundary. These harmful defects seriously affect the carrier transport and hinder the further improvement of the power conversion efficiency of perovskite solar cells. Therefore, the latest research progress on passivated perovskite solar cells defects in recent years is summarized. According to the current research results, a suitable passivating strategy is summarized to passivate the defects in perovskite solar cells, thus improving the efficiency and the stability of perovskite solar cells.
