本研究利用濺鍍的方式沉積銦鋅氧化物 (Indium Zinc Oxide，簡稱IZO) 薄膜，將其製作成能穿透可見光及近紅外光的透明導電薄膜，在可見光區有80~90% 的穿透度，而在近紅外光區有90% 以上的穿透度，薄膜片電阻約為24Ω/□。再將此IZO透明導電薄膜應用於鈣鈦礦太陽能電池的對電極，並藉由緩衝層三氧化鉬 (Molybdenum(VI) oxide，MoO3) 的保護，使濺鍍製程於元件上得以實踐，完成一雙面透光的鈣鈦礦太陽能電池，其最高效率可達16.4%。
我們接著使用此雙面透光鈣鈦礦太陽能電池，與矽晶太陽能電池串疊，完成一鈣鈦礦/矽晶串疊型元件，因鈣鈦礦的能隙 (Band gap) 大小，剛好能不錯的分割矽晶太陽能電池的吸收光譜，所以能將太陽光平均分配給鈣鈦礦及矽晶元件，使兩元件的電流值匹配，而較高能量的光子能由鈣鈦礦元件轉換出較高的電壓，因此提升串疊型元件整體的效率。此鈣鈦礦/矽晶串疊型元件的效率能達到19.5%。
而我們亦利用濺鍍IZO透明導電膜的技術，完成一non-FTO太陽能電池，實現的方法為，將FTO玻璃取代為濺鍍在載玻片上的鈦金屬。鈦金屬於高溫燒結時，表面會形成緻密氧化層，使鈦金屬不會全數生成金屬氧化物，而失去其導電電極的特性，為一能承受高溫的導電電極。此鈦金屬基板製作之non-FTO太陽能電池，效率可達13.8%。最後將此non-FTO元件之結構，應用於康寧的超薄玻璃上 (Corninig glass)，完成一效率13.6% 的可撓式鈣鈦礦太陽能電池。

Perovskite solar cells (PSCs) are one of the most promising candidates for next-generation solar cells because of their high power conversion efficiencies and easily fabrication. Recently, light and thermal stability of PSCs are resolved gradually so the commercialization of PSCs can be expected. In this study, we fabricate semitransparent PSCs by sputtering indium zinc oxide (IZO) as counter electrode then make a perovskie / silicon mechanically stacked tandem. These semitransparent PSCs can be an efficiency improvement component for silicon solar cells without any modification on existing silicon solar cells.The semitransparent PSCs show power conversion efficiency (PCE) of 16.4% from front illumination (FTO side) and 15.2% from back illumination (IZO side).We also use the technique of sputtering IZO to make a non-FTO back illumination PSCs by substituting FTO with sputtered Titanium (Ti) thin film and the non-FTO PSCs show PCE of 13.8%. Eventually, we applied the structure of non-FTO PSCs to Corning ultra thin glass to make flexible PSCs and also keep the PCE at 13.6%.
