摘要:
在高湿度空气环境中，通过不同质量浓度的碘甲胺溶液与PbI2薄膜反应制备钙钛矿薄膜与电池器件，研究碘甲胺质量浓度对薄膜形貌和太阳能电池性能的影响机理，发现高浓度碘甲胺溶液有利于纳米晶粒的致密薄膜生成，而低浓度碘甲胺溶液则形成带孔的微米晶粒薄膜，均不利于制备高性能钙钛矿电池．为克服单一溶液反应存在的问题，在改进的双溶液旋涂法中，利用8 mg/mL低浓度的碘甲胺溶液与PbI2薄膜反应10 s，再分别用15和30 mg/mL碘甲胺溶液对薄膜后处理，获得了晶粒粒径大，且致密的钙钛矿薄膜，碘化铅残留很少．相应的，在空气中制备的钙钛矿太阳能电池展示了更好的光电转化性能．
Abstract:
CH3NH3PbI3 perovskite films and the perovskite solar cells were prepared via reaction of PbI2 films and CH3NH3I (MAI) solutions of different concentrations under high-humidity ambient conditions．It was found that high concentration MAI solution contributes to the formation of the dense films with nano-scale perovskite grains, while low concentration MAI solution results in rough films with micrometer-scale grains and many voids and openings. None of these films could benefit the high-performance perovskite solar cells from the aspects of grain boundaries and coverage area. In order to overcome the disadvantage of the single solution method，modified double solution method was developed. Eight mg/mL low concentration MAI solution was used to react with PbI2 films for 10 s and then high concentration MAI solutions of 15 and 30 mg/mL were used for post-treatment. Consequently, dense CH3NH3PbI3 perovskite films with large-scale grains with little PbI2 residue were obtained. Accordingly, the perovskite solar cells fabricated in ambient conditions by this method exhibit a good photovoltaic performance.
