鈣鈦礦太陽能電池，相對其他太陽能電池有著低成本的製造和良好的光電轉換效率，最高轉換效率已有25.2%，接近長久以來的矽晶太陽能電池光電轉換效率。其中旋轉塗佈法是鈣鈦礦( PVSK )中最常用的製程，具有易操作且高穩定性等優點，因此可以推斷主要影響電池效率的因素在鈣鈦礦的主動層上，為了進一步提升電池元件的效率，又能使元件效率再現性穩定，實驗以鈣鈦礦前驅溶液，添加氯苯( CB )、乙酸乙酯( EA )反溶劑來進行優化。
在進行添加不同CB與EA比例的實驗結果後，證實能改善鈣鈦礦主動層的缺陷部份，減少鈣鈦礦層薄膜的電荷累積，提升光電轉換上的整體電性；在將兩邊的實驗結果，相互比較會發現實驗分析的結果有著相同趨勢；其中比較不同的點在於，添加EA在電流強度上比起添加CB有更佳的提升效果，而添加CB的元件在內部電阻上比添加EA有更好的改善。在提升效率上，添加CB在效率上從16.31%提升到18.17%，添加EA的效率則提升到17.60%。

Compared with other solar cells, perovskite solar cells have low-cost manufacturing and good photoelectric conversion efficiency. The highest conversion efficiency is 25.2%, which is close to the long-term photoelectric conversion efficiency of silicon crystal solar cells. Among them, the spin coating method is the most commonly used process in perovskite (PVSK), which has the advantages of easy operation and high stability. Therefore, it can be inferred that the factors that mainly affect the efficiency of the battery are on the active layer of the perovskite, in order to further improve the battery The efficiency of the component can also make the efficiency of the component reproducible and stable. The experiment was optimized with the perovskite precursor solution and the addition of chlorobenzene (CB) and ethyl acetate (EA) antisolvent.

After conducting experiments with different ratios of CB and EA, it was confirmed that it can improve the defective part of the perovskite active layer, reduce the charge accumulation of the perovskite layer film, and improve the overall electrical performance of the photoelectric conversion; by comparing the results, It is found that the results of experimental analysis have the same trend. The difference between them is that the addition of EA is better than the addition of CB to improve the current strength, and the element with CB has a higher internal resistance than EA. There are better improvements. In terms of improving efficiency, the efficiency of adding CB increased from 16.31% to 18.17%, and the efficiency of adding EA increased to 17.60%.
