| 英文摘要 | Carbon-based hole-conductor-free perovskite solar cells (C-PSCs) are considered as a promising photovoltaic technology toward commercialization, owing to their low cost and superior stability. However, efforts to further improve efficiency have been hampered by 10 the hole-extraction barrier at the Schottky contact between carbon and perovskite. A conventional approach to resolving this issue is incorporating a hole-transport material (HTM) in the mesoscopic skeleton or chemical modification of the carbon electrode. Here, we show an innovative strategy that using solution-processed hydrogen molybdenum bronzes (HxMoO3-y) nanobelts, an n-type HTM with high work function and electrical conductivity, as the sole electrode material to enhance the hole-extraction process and result in efficient PSCs for the first time. The mesoscopic cell configuration of FTO/c-TiO2/m-TiO2/m-Al2O3/HxMoO3-y with perovskite infiltration 15 delivered a champion power conversion efficiency (PCE) of 14.5%, which compares favorably with that of 13.3% for the typical high temperature C-PSCs. The increase in cell efficiency stems primarily from the enhancement in open circuit voltage and short circuit current, which is owed to the HxMoO3-y electrode with more favorable energy alignment and higher hole-extraction ability than carbon electrode. These results open up the potential of HxMoO3-y nanobelts as an efficient electrode for realizing high-performance mesoscopic PSCs. |
