一种Mo-二氧化钛-AgNWs柔性钙钛矿太阳能电池及其制备方法
摘要：
为制备基于Mo‑TiO2‑AgNWs柔性钙钛矿太阳能电池，首先，将购置超细银纳米线分散到离子液(EMIMBF4)和超纯水(体积比1:5~10)混合溶液中，连续搅拌使AgNWs均匀分散，利用旋涂沉积技术将AgNWs沉积在聚对苯二甲酸丁二酯(PET)基底上得到透明电极；其次，在TiO2前驱体溶液中同时引入Mo离子掺杂和AgNWs，旋涂沉积得到Mo‑TiO2‑AgNWs电子传输层，随后沉积C60自组装单层；最后，采用两步连续法沉积CH3NH3I溶液和PbI2溶液得到CH3NH3PbI3，旋涂沉积空穴传输材料(Spiro‑OMeTAD)，并利用真空蒸镀技术沉积Au对电极。
摘要（英）：

The objective of the invention is to prepare a TiO2-AgNWs flexible perovskite solar cell, At first, that purchase ultrafine silver nanowire are dispersed in a mixed solution of an ionic liquid (EMIMBF4) and ultrapure water (volume ratio of 1: 5 to 10), AgNWs are uniformly dispersed by continuous stir, and AgNWs are deposited on a polybutylene terephthalate (PET) substrate by a spin coating deposition technology to obtain a transparent electrode; Secondly, Mo ion doping and AgNWs were simultaneously introduced into TiO2 precursor solution, and Mo-TiO2-AgNWs electron transport layer followed bydeposition of C60 self-assembled monolayer; Finally, CH3NH3PbI3 was prepared by two-step continuous deposition of CH3NH3I and PbI2 solutions. The deposited hole transport material (Spiro-OMeTAD) is subjected to spin coating, and Au counter electrode was deposited by vacuum evaporation technique.
