以单壁碳纳米管（SWNT）为透明顶电极，聚甲基丙烯酸甲酯（PMMA）为外涂层，制备了玻璃/FTO/TiO_2/CH_3NH_3PbI_3结构的卤化铅钙钛矿太阳能电池（PSC）。基于单壁碳纳米管的PSC不需要昂贵的金属电极和空穴传输材料，但由于PMMA对单壁碳纳米管的致密化作用，其产生了11.8%的可观的功率转换效率。所得到的器件表现出减小的滞后、改善的稳定性和增加的功率转换效率。
Lead halide perovskite solar cells (PSCs) with a structure of glass/FTO/TiO_2/CH_3NH_3PbI_3 with single-walled carbon nanotubes (SWNT) as the transparent top electrodes, followed by polymethyl methacrylate (PMMA) over-coating were fabricated. The SWNT-based PSCs do not require expensive metal electrodes and hole-transporting materials yet produce a decent power conversion efficiency of 11.8%, owing to the densifying effect of SWNTs by PMMA. The resulting devices demonstrate reduced hysteresis, improved stability, and increased power conversion efficiency.
