On the other hand, organic-inorganic hybrid perovskites have the ambipolar property, which can produce voltage by themselves under light irradiation. In this work, we combine the P3HT:ICBA and perovskite system by introducing perovskite as high voltage driver into P3HT:ICBA solar cells to enhance their voltage performance. In order to reduce the energy consumption and increase more extensive choices of materials in active layers, we develop the whole non-annealing fabrication process, the interconnecting layers, perovskite layer and hole transport layer of perovskite are process without annealing. Compared with the standard P3HT:ICBA solar cell, the CH3NH3PbI3-modified P3HT:ICBA solar cell with 3nm MoO3/ZnO interconnecting layers show significant enhancement in open circuit voltage (Voc) and power conversion efficiency (PCE), increase from 0.86V to 1.60V and 3.34% to 4.35%, respectively. Under more than 210 days (5,040 hours) storage, compared 210th with 1st day measuring Voc results of the CH3NH3PbI3-modified P3HT:ICBA solar cell with 3nm MoO3/ZnO decays within 3%. Besides, the Voc of the modified solar cell can still maintain above 1.55V, which is valuable record because normally the commercial appliances need to be driven above 1.50V. To simplify the manufacturing process, we also try to remove the electron and hole transport layers of perovskite. Compared with the standard P3HT:ICBA solar cell, the CH3NH3PbI3-modified P3HT:ICBA solar cell with 11nm MoO3 interconnecting layer exhibits great improvement in Voc and PCE, raise from 0.82V to 1.28V and 3.03% to 3.40%, respectively. It proves that single perovskite layer can be the high voltage driver of P3HT:ICBA solar cells. Finally, for the practical application, we successfully prove that our modified solar cells can provide enough voltage output to drive commercial appliances no matter under one sun or dim light irradiation.2811062 bytesapplication/pdf論文公開時間: 2021/3/8論文使用權限: 同意有償授權(權利金給回饋學校)鈣鈦礦高驅動電壓太陽能電池中間層perovskitehigh voltage drivermodified solar cellsinterconnecting layers[SDGs]SDG7thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/273111/1/ntu-105-R01527033-1.pdf
