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).

该研究的重点是钙钛矿太阳能电池的溶液处理的分层结构的界面工程。使用介孔TiO2层作为电子收集器，并通过更改钙钛矿晶粒尺寸和形态，基于优化溶液涂层过程的优化，可以改善三阳离子（CS，MA，FA）的光伏性能（CS，MA，FA）。获得高密度和大谷物钙钛矿晶体层，在光伏电池上表现出高于20％的高转化效率。结果已提交给期刊，目前正在审查中。我还准备了免费的免费钙壶，这是我提议的主要部分。基于二氧化碳基于二氧化碳的二氧化碳（MBI）钙钛矿由于其无毒和稳定性而进行了研究。可以通过选择各种脚手架（平面，介孔（解剖酶和溪））来调整MBI的形态，并通过改变前体溶液的组成来改进。效率为0.3％或更高，因为迄今为止报告的MBI钙钛矿效率最高，并且事实证明，对空气中的环境水分最多可稳定。这些结果发表在两个同行审查期刊（ACS应用材料和界面，RCS进步）中。
