제목 Air-Stable, Hole-Conductor-Free High Photocurrent Perovskite Solar Cells with CH3NH3PbI3-NiO Nanoparticles Composite
초록 We report an air-stable, hole-conductor-free (HCF), high photocurrent PSC based on CH3NH3PbI3-NiO nanoparticles (MAPbI3-NiO NPs) composite. By introducing the CH3NH3PbI3-NiO composite into the active layer, the HCF-PSCs with FTO/c-TiO2/mp-TiO2/MAPbI3-NiO/Au architecture have been fabricated under ambient conditions. Compared to the power conversion efficiency (PCE) of MAPbI3-based HCF-PSC (i.e., 5.43%), the MAPbI3-NiO NPs composite-based HCF-PSC showed a high PCE of 12.14 %. This increase in PCE is mainly due to a remarkable increase in photocurrent density, suggesting that the MAPbI3-NiO composite enhances the charge carrier generation via improving photo-absorption and fast hole-conduction by NiO NPs. More interestingly, the composite-based HCF-PSCs without encapsulation showed remarkable air stability with retaining ~90 % of its original PCE and ~94% of both Jsc and FF for 60 days under ambient environment.
