The study was focused on the interface engineering of the solution-processed layered structures of perovskite solar cell. Using mesoporous TiO2 layers as electron collector and, photovoltaic performance of triple cation (Cs, MA, FA) lead halide perovskite was improved by changing the perovskite grain size and morphology based on optimization of the recipe of solution coating process. High density and large grain perovskite crystal layers were obtained, which exhibited high conversion efficiency exceeding 20% on photovoltaic cell. The result was submitted to journal and presently under review. I also prepared lead free perovskites which is a main part of my proposal. Bismuth-based lead free methyl ammonium bismuth iodide (MBI) perovskite was studied due to its non-toxicity and stability. The morphology of MBI could be tuned via choosing various scaffolds (planar, mesoporous (anatase and brookite)) and improved by altering the composition of precursor solution. Efficiency of 0.3% and more was obtained as the highest efficiency of MBI perovskite so far reported and devices were proved to be stable against ambient moisture in air up to 10 weeks. These results were published in two peer-review journals (ACS Applied Materials and Interfaces, RCS Advances).

本论文主要研究钙钛矿太阳能电池溶液处理层状结构的界面工程。以介孔TiO2为电子收集层，通过优化溶液包覆工艺配方，改变钙钛矿相的晶粒尺寸和形貌，提高了三重阳离子（Cs，MA，FA）卤化铅钙钛矿的光伏性能。获得了高密度、大晶粒的钙钛矿晶体层，在光伏电池上表现出超过20%的高转换效率。结果已提交给期刊，目前正在审查中。我还准备了无铅钙钛矿，这是我的建议的主要部分。铋基无铅钙钛矿型碘化铋（MBI）具有无毒、稳定等优点。MBI的形态可以通过选择不同的支架（平面，介孔（介孔和板钛矿））进行调节，并通过改变前体溶液的组成来改善。到目前为止，MBI钙钛矿的最高效率为0.3%或更高，并且设备被证明在空气中对环境湿度稳定长达10周。这些结果发表在两个同行评审期刊上（ACS Applied Materials and Interfaces，RCS Advances）。
