隨著科學家們的不斷努力，鈣鈦礦太陽能電池的效率從起初的3.8 %到現在有25.5 %，而一個優異的電洞傳輸材料對高效率鈣鈦礦太陽能電池來說是不可或缺的，本文第一部分延續實驗室學姊之化合物XYC系列，探討羧酸基與不同銨鹽陽離子作為電洞傳輸材料對反式鈣鈦礦太陽能電池的影響，發現透過TBA+的化合物XYC108有著優異的溶解度，初步效率測試有17.31 %，接下來會研究更詳細的電池性質。 第二部分為比較二苯硫、二苯亞?及二苯?三者作為中心拉電子基團而成的D-A-D型態SU系列分子，作為電洞傳輸材料對反式鈣鈦礦太陽能電池的影響，發現三者都具有很好的熱穩定性及能階，初步比較有優於PEDOT:PSS的光電轉換效率。 ;Nowadays, the PCE of perovskite solar cells have reached 25.5 % compared to initial 3.8 %. Owing to studies of different kinds of hole-transporting materials. In the first part of this article, we continue the XYC series to explore the influence of carboxylic acid groups and different ammonium salt cations as hole transport materials on inverted perovskite solar cells. It is found that the XYC108 through TBA+ has excellent solubility, which can improve film-forming ability. The preliminary efficiency test is 17.31%. The second part is SU series compounds. The D-A-D type molecules, which have diphenylsulfide, diphenylsulfioxide and diphenylsulfone as the central electron-withdrawing group, as hole transporting materials in inverted perovskite solar cells. It is found that SU series all have good thermal stability and suitable energy level. The better performance gives it potential as a promising HTM for the further advance of PSCs.
