鈣鈦礦太陽能電池是最近三年來新興的一種高效率光伏器件。它不僅在短短三年的時間裡達到20.1%的光電轉化效率，而且由於它的製程靈活可控、成本相對低廉而吸引了全世界很多學者的關注。本研究借鑒了多種鈣鈦礦的鍍膜方法，經過嘗試，使用旋轉塗佈法獲得了較為優化的平面異質結構太陽能電池的實驗製程。本研究分為兩部分，一為鈣鈦礦薄膜的塗佈研究，二為鈣鈦礦太陽能電池的表現分析。
在第一部分中，又可分為兩個小節，一步法的配比優化和兩步法的創新探索。在一步法的優化中，研究了一步法中複雜的溶質配比對於鍍膜結果的影響，對膜層的表面形貌、結晶情況以及光學特性進行了分析總結。在兩步法的探索中，本研究參考了當前最新的鈣鈦礦膜層生長設計趨勢——分子間交換法，利用這一思路對實驗步驟進行簡化、優化，最終獲得了表面形貌及結晶情況與現有方法相若的鈣鈦礦膜層。
在第二部分中，本研究分析了前一部分若干不同鈣鈦礦薄膜製得的太陽能電池性能。不僅觀測到了鈣鈦礦太陽能電池中常見的I-V滯回現象，探討了鍍膜方式對I-V滯回現象的影響，還初步研究了不同組鈣鈦礦太陽能電池中的載子存活壽命，藉由類似的物理模型探索了鈣鈦礦太陽能電池中載子存活壽命與光強間的關聯。

The alkyl-ammonium metal trihalide perovskites are an exciting new class of solar absorber materials and have exhibited a rapid increase in solar cell efficiencies throughout the past three years to over 20%. Good quality and high orientation perovskite crystalline films were expected to less recombination and faster electron flux. Two common deposition method is utilized to assemble planar heterojunctioned perovskite solar cells, one-step solution method and two-step sequential solution method. Spin-coating is the most common depositing process of perovskite. In this work, we used a novel method to synthesized modified PbI2 film which could be used for intramolecular exchange in two-step method. And discussed the influence of different one-step recipe to perovskite thin film formation. I-V hysteresis was also investigated, finding that hysteresis phenomena fitting theoretical assumption. Intensity modulated photovoltage spectroscopy (IMVS) measurement was introduced into perovskite solar cells for carrier life time calculating. This work preliminarily discussed the impact factor of perovskite thin film deposition, I-V hysteresis and carrier life time.
