ITO/PEDOT:PSS_AI4083/Perovskite/PCBM(C60)/Al是標準P-I-N結構一步法製作的有機-無機鈣鈦礦太陽能電池。本實驗將從目前較成熟的鉛鹵鈣鈦礦材料CH3NH3PbI3 著手，透過置換鹵素元素研究新材料電子結構、載子傳播及光性與穩定性。再經由調整退火時間長短及退火溫度高低，比較不同條件之下新材料的表面型態。金屬鹵化物鈣鈦礦材料因為具有遠高於非晶矽的載子移動率、激子擴散長度，更可以透過摻雜或置換元素進而調整能隙，應用的波長範圍從可見光到UV且可以再製做成異質接面，因此有極大的潛能。此外，本實驗全程都是採取低溫溶劑製程成長在基板上，這在未來有機會可運用roll-to-roll印製製程進而降低成本。
