以多壁碳纳米管（CNTs）和甲胺（CH 3 NH 2）修饰的钙钛矿太阳能电池（PSCs）为电源，CNT/TiO 2为光阳极，设计了一种自供电光电催化（PEC）装置。在PSCs中，碳纳米管和CH 3 NH 2被用来修饰钙钛矿和碳电极之间的界面，以提高光电性能。特别地，CH 3 NH 2诱导的CH 3 NH3 PbI 3钙钛矿薄膜的表面愈合和CNT充当单个钙钛矿纳米颗粒之间的电荷传输路径，以促进由碳电极收集光生空穴。在用碳纳米管和CH 3 NH 2修饰后，实现了10.39%的功率转换效率。在光阳极中，CNT修饰的TiO 2电极加速了电子-空穴的分离和传输，从而提高了降解性能。将CNT和CH 3 NH 2修饰的PSC与CNT/TiO 2组装后，太阳能驱动的PEC体系对罗丹明B（RhB）表现出较高的PEC降解率。串联装置对RhB的最佳降解效率在80 min后接近100%。这种低成本的串联装置在污染物降解研究中具有很好的应用前景。
In this study, a self-powered photoelectrocatalytic (PEC) device was designed using multi-walled carbon nanotubes (CNTs) and methylamine (CH3NH2) modified perovskite solar cells (PSCs) as the power source and CNT/TiO2as the photoanodes. In the PSCs, CNTs and CH3NH2were used to modify the interface between the perovskite and carbon electrode to improve the photoelectronic performance. In particular, CH3NH2induced surface-healing of the CH3NH3PbI3perovskite thin films and the CNTs acted as a charge transport pathway among individual perovskite nanoparticles to facilitate the collection of photogenerated holes by the carbon electrode. A power conversion efficiency of 10.39% was achieved after modification with the CNTs and CH3NH2. In the photoanodes, the CNT-modified TiO2electrode accelerated the electron–hole separation and transportation, thereby improving the degradation performance. After assembling the PSCs modified using CNT and CH3NH2with CNT/TiO2, the solar-driven PEC system exhibited a high PEC degradation rate with rhodamine B (RhB). The optimal degradation efficiency for RhB with the tandem device was close to 100% after 80 min. This low-cost tandem assembly has promising applications in pollutant degradation research.
