基于P3HT:PCBM光伏电池的倒置结构和正置结构的研究

We analyzed the conductive type of organic photovoltaic cell based on the P3HT: PCBM active layer, through the single charge carrier device. By preparation of four different cells include the normal cells and inverted cells, we came to a conclusion that the inverted cells shown advantage. The charge transport properties of ITO/ZnO/P3HT-PCBM/MoO3/Al organic device with an inverted architecture have been investigated by using current-voltage (I-V) and capacitance-voltage(C-V) techniques. The electrical parameters like series resistance Rs, ideality factor n, and barrier height to be 48.23 Ω,1.6 and 0.8 eV had been analyzed using I-V. The open circuit voltage Voc, short circuit current density Jsc, fill factor FF, PCE values for the organic solar cell are found to be, 0.57V, 0.74mA, 61%, 2.9%, respectively.
