本研究使用四氯化鈦在FTO導電玻璃上覆蓋一層緻密的二氧化鈦阻擋層，避免鈣鈦礦層直接接觸到FTO導電玻璃造成效率降低。接著在二氧化鈦緻密層上以電泳沉積之方式，製備多孔的奈米二氧化鈦層，並透過改變電泳沉積的參數，探討二氧化鈦層的特性。多孔的二氧化鈦層除了可以有效的降低電子電洞復合率，且可使鈣鈦礦較易附著，達到提高鈣鈦礦電池效率的目的。在旋塗上鈣鈦礦層之後，在鈣鈦礦層上旋塗一層電子傳輸層，並使用電子蒸鍍機沉積一層80nm的金做為背電極，完成電池之製作。本實驗通過場發射掃描電子顯微鏡(FE-SEM)觀察二氧化鈦層的表面形貌，並利用UV-Vis，IPCE，還有光電轉換效率量測分析，以尋求最佳的電泳沉積參數。

In this study, TiCl4 treatment was used to cover the FTO conductive glass with a dense titanium dioxide layer to avoid the efficiency of the perovskite layer directly contacting the FTO conductive glass. Then, a mesoporous TiO2 layer was prepared by electrophoretic deposition on the dense layer of titanium dioxide, and the characteristics of the TiO2 layer were investigated by changing the parameters of electrophoretic deposition. The mesoporous TiO2 layer can effectively reduce the electron hole recombination rate, and can make the perovskite easier to adhere, thereby achieving the purpose of improving the efficiency of the perovskite battery. After spin-coating the perovskite layer, an electron transport layer was spin-coated on the perovskite layer, and a layer of 80 nm gold was deposited as electrode to complete the fabrication of the Perovskite solar cell. In this experiment, the surface morphology of the TiO2 layer was observed by field emission scanning electron microscopy (FE-SEM), and UV-Vis, IPCE, and photoelectric conversion efficiency measurement were used to find the best electrophoretic deposition parameters.
