| 英文摘要 | Poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) has been widely adopted as hole transport material (HTM) in inverted perovskite solar cells (PSCs), due to high optical transparency, good mechanical flexibility, and high thermal stability; however, its acidity and hygroscopicity inevitably hamper the long-term stability of the PSCs and its energy level does not match well with perovskite materials with a relatively low open-circuit voltage. In this work, p-type delafossite CuCrO_2 nanoparticles synthesized through hydrothermal method was employed as an alternative HTM for triple cation perovskite (FAPbI_3)_(0.87) (MAPbBr_3)_(0.13) _(0.92) (CsPbI_3)_(0.08) (possessing better photovoltaic performance and stability than conventional CH_3 NH_3 PbI_3) based inverted PSCs. The average open-circuit voltage of PSCs increases from 908 mV of the devices with PEDOT:PSS HTM to 1020 mV of the devices with CuCrO_2 HTM. Ultraviolet photoemission spectroscopy demonstrates the energy band alignment between CuCrO_2 and perovskite is better than that between PEDOT:PSS and perovskite, the electrochemical impedance spectroscopy indicates CuCrO_2 -based PSCs exhibit larger recombination resistance and longer charge carrier lifetime than PEDOT:PSS-based PSCs, which contributes to the high V OC of CuCrO_2 HTM-based PSCs. |
