近年來，許多不同類型的鈣鈦礦太陽能電池設計都嘗試提高兩側入光面的穿透度，其中包含了背接觸式以及夾層結構，為了比較其雙面與單面照射時的情境，本研究中模擬了雙面同時照光的情境量測，以夾層結構作為標準元件進行量測，其中，標準元件是利用FTO作為底電極，經由噴塗製程製備TiO2緻密層，接著，以SnO2奈米顆粒作為支架層後沈積一層鈣鈦礦以及電洞傳輸層(Spiro)，其電洞傳輸層上方的電極則是利用金或是MoO3/IZO，電池元件在上電極以金和MoO3/IZO分別在玻璃入光面之逆向掃描時得到了15.92%與13.04%的轉換效率，最後，比較以金屬與透明導電膜作為電極在雙面以不同光強度照射下之元件性能。
研究過程中，設計了一項不同於夾層與背接觸式結構的混合型結構，結構中之載子特性同時包含了背接觸式及夾層結構的載子移動路徑，主要是利用素玻璃作為基板，以多孔二氧化鈦作為基底，塗佈聚苯乙烯微球於多孔二氧化鈦上方，經由反應離子蝕刻的方式控制球形大小，再用真空濺鍍的方式濺鍍半透明膜層，最後去除聚苯乙烯球，形成半透明多孔電極，接著，利用此結構之電極製成電池元件，分別以金或是MoO3/IZO作為上電極，在金作為上電極時，於逆向掃描得到了4.35%的轉換效率，以MoO3/IZO作為電極時，在逆向掃描時的玻璃面及IZO面分別得到了2.84%及3.18%之轉換效率，最後將混合型結構之鈣鈦礦太陽能電池以雙面照光進行量測並討論。

Bifacial semi-transparent perovskite solar cells (PSCs) are a popular research project.
Currently, there has not been much discussion over simultaneous illumination on both sides of solar cells. These types of solar cells have lower performance than the device with metal electrode when irradiating on one side. For the purpose of this study, we designed a double-sided lighting environment to measure the sandwich and hybrid structure. Gold and indium zinc oxide (IZO) were used as counter electrodes to observe responses of the components under different light intensities on both sides. Thus, in this work, we simulated a double-sided lighting environment and compared the performance of devices based on electrodes using gold and indium zinc oxide (IZO).
