鈣鈦礦太陽能電池為當今備受矚目之新型太陽能電池之一，其轉換效率在短短二十年間由約12 % 提升至25.7%，而電洞傳輸材料在提高元件性能方面作為一重要角色。根據文獻相關報導，有機環狀小分子有利於孔柱狀之排列堆積，然而目前有機環狀小分子應用於光電材料之領域甚少，作為鈣鈦礦太陽能電池之電洞傳輸材料仍有待開發。本文研究並合成三種大小之氧橋芳杯環狀化合物C-TP、C-TBPA、CTPPy，作為反式鈣鈦礦太陽能電池中之電洞傳輸材料，發現三者皆具有良好的熱穩定性及溶解度，而分子中的氮原子預期能達到鈍化鈣鈦礦層之作用，使鈣鈦礦晶形更為平整，有利於電荷之傳遞。以三者所組成之元件初步之光電轉換效率優於標準品PEDOT：PSS，在光電材料上具有潛在之發展性。;Perovskite solar cells (PSCs), as one of the most attractive novel materials solar cells nowadays, have dramatically increased the power conversion efficiency (PCE) from about 12 % to 25.7 % in two decades. Furthermore, hole transporting materials (HTMs) play an important role in the enhancement of device performance. According to relevant literatures, organic cyclic molecules are beneficial to the arrangement and stacking of pore columnars. However, they were rarely used in the field of optoelectronic materials nowadays, neither as HTMs in PSCs. Herein, three different kinds of oxa-calixarene macrocycic compounds, C-TP、C-TBPA、C-TPPy, as hole transporting materials for inverted perovskite solar cells were designed and synthesized. It was found that all of them show great thermal stability and solubility, the nitrogen atoms of moleculars are beneficial for not only potential defect passivation for perovskite film, making it grow smoothly on crystal, but also the hole mobility. The inverted PSCs based on three compounds show better PCE than standard PEDOT：PSS, provide the potential applications on Photoelectronic materials.
