Journal of Photochemistry and Photobiology C: Photochemistry Reviews ( IF 13.6 ) Pub Date : 2017-12-01 , DOI: 10.1016/j.jphotochemrev.2017.11.002

The breakthrough discovery of organic-inorganic hybrid perovskite materials for converting solar energy into electrical energy has revolutionized the third generation photovoltaic devices. Within less than half a decade of rigorous research and development in perovskite solar cells, the efficiency is boosted upto 22%. Aforesaid high PCE is accredited to high optical absorption properties, balanced charge transport properties, and longer diffusion lengths of carriers. Two dominant perovskite solar cell architecture has evolved; n-i-p, and p-i-n with mesoporous or planar heterojunction. In planar heterojunction configuration, perovskite light harvester is layered between hole/electron transport layers and the electrodes. The electron and hole transporting films increase charge collection efficiency and reduce recombination at interfaces. In the following review, we present a critical survey of the recent progress in perovskite absorber and charge transport materials that account for the exceptionally higher PCE of perovskite devices. Furthermore, numerous fabrication techniques and device architectures are summarized.

钙钛矿太阳能电池的前沿,机遇与挑战:一项重要评论

用于将太阳能转化为电能的有机-无机杂化钙钛矿材料的突破性发现彻底改变了第三代光伏设备。在不到钙钛矿型太阳能电池严格研发的不到五年的时间里,效率提高了22%。前述的高PCE被证明具有高的光吸收特性,平衡的电荷传输特性以及较长的载流子扩散长度。两种主要的钙钛矿太阳能电池结构已经发展;压区,并用中孔或平面异质结钉住。在平面异质结配置中,钙钛矿集光器位于空穴/电子传输层和电极之间。电子和空穴传输膜提高了电荷收集效率并减少了界面处的复合。在下面的评论中,我们对钙钛矿吸收剂和电荷传输材料的最新进展进行了重要的调查,钙钛矿吸收器的PCE异常高。此外,总结了许多制造技术和器件架构。
