This paper reports the effect of perovskite layer on enhancing the inverted type hybrid organic solar cell performance. The mixtures of methylammonium iodide (CH3NH3I) and lead (II) chloride (PbCl2) were dissolved in N,N-Dimethylformamide (DMF) solvent and was spin-coated onto fluorine-doped tin oxide (FTO) glass substrate coated with zinc oxide nanorod arrays (ZnONRAs). The poly (3-hexylthiophene-2,5-diyl) (P3HT) film was then spin-coated onto CH3NH3I(3-x)PbClx perovskite layer, followed by silver (Ag) deposition using magnetron sputtering technique. The FTO/ZnO seed/ZnONRAs/CH3NH3PbI(3-x)Clx /P3HT/Ag device was fabricated. A device without perovskite layer was also fabricated for comparison. A power conversion efficiency (PCE) of 0.56% was achieved with the introduction of perovskite layer. The PCE was approximately six times greater than the device without perovskite layer, as a result of wider light absorption range and higher exciton dissociation efficiency. |
