Abstract:	鈣鈦礦太陽能電池之光電轉換效率在近年已由4%大幅成長到23%，欲提升效率，研發一種更能有效提取電洞並傳遞電洞之電洞傳輸材料為重要關鍵之一。本篇設計了以三聯噻吩（2,2′:5′,2"-terthiophene）為主體之電洞傳輸材料WZ40、WZ102、WZ103，藉由改變拉推電子基的強弱，觀察其對光電轉換效率的影響。WZ系列之材料皆展現出非晶態特性，且有合適的熱穩定性，其中WZ102在鈣鈦礦太陽能電池中的光電轉換效率可達11.91%，優於PEDOT:PSS的10.23%，是一款應用在鈣鈦礦太陽能電池上相當具有潛力之電洞傳輸材料。 ;The power conversion efficiency（PCE）of perovskite solar cells（PSCs）has shown a significant enhancement from 3.8 % in 2009 to 23.7 % in 2018. To increase the PCE, developing a hole-transporting material（HTM）which has superior ability of positive charge extraction and transportation is one of the important factors. In this article, three terthiophene-based hole-transporting materials named WZ40, WZ102, WZ103 have been synthesized. The compounds of WZ series exhibit amorphous property and appropriate thermal stability. However, the perovskite solar cell employing WZ102 generates a power conversion efficiency of 11.91 %, which is higher than the power conversion efficiency of 10.23 % based on PEDOT:PSS. The better performance gives it potential as a promising HTM for the further advance of PSCs.
