In this study, we have developed the multilayered solar cells fabricated by both vacuum and solution processes. The open-circuit voltage increases with the insertion of carrier selective layers and with the increase in ionization potential (IP) of donor materials. The contributions of ultrathin titania nanosheet (TN) crystallites were also studied in both an inverted bulk-heterojunction (BHJ) cell in indium tin oxide (ITO)/ titania nanosheet (TN)/poly(3-hexylthiophene)(P3HT): phenyl-C61-butyricacid methylester (PCBM) active layer/ MoO3/Ag and a conventional BHJ cell in ITO/ MoO3/ P3HT:PCBM active layer/ TN/ Al multilayered photovoltaic devices. The ultra-thin TN film decreased the leakage current and increased the open circuit voltage (VOC), fill factor (FF), and power conversion efficiency (η).We also developed the new-types of discotic liquid crystals for the spontaneous perfect homeotropic alignment. .

在本研究中，我们开发了真空法和溶液法制备的多层太阳能电池。开路电压随着载流子选择层的插入和给体材料电离电位的增加而增加。研究了超薄二氧化钛纳米片（TN）晶体在氧化铟锡(ITO)/二氧化钛纳米片(TN)/聚（3-己基噻吩）（P3HT）：苯基- c61 -丁酸甲基酯（PCBM）活性层/ MoO3/Ag中倒置体积异质结（BHJ）电池和在ITO/ MoO3/ P3HT:PCBM活性层/ TN/ Al多层光伏器件中的作用。超薄TN薄膜降低了泄漏电流，提高了开路电压（VOC）、填充系数（FF）和功率转换效率（η）。我们还开发了新型的圆盘状液晶，用于自发的完美同向取向。
