摘要

The applications of wide-bandgap (WBG) perovskite solar cells (PSCs) arelimited by their subpar efficiency and stability due to their high density ofdefects, especially those at interfaces. Theoretical analyses suggest a monolayerof molecules, which is of minimum thickness and, hence, minimumresistance across the interface, possessing multifunctional groups and a permanentdipole, should effectively passivate the defects and minimize energylosses at interfaces. Herein, a self-assembled monolayer (SAM) composed ofamphiphilic molecules is designed and assembled as the interface layer toreduce the energy loss and enhance interface coupling between the perovskiteand hole transport layer. It is found that the SAM also builds a back surfacefield through a p-type doping effect, which promotes hole extraction andsuppress the carrier recombination. Consequently, a remarkable power conversionefficiency (PCE) of 20.4 in parallel with a high open-circuit voltageup to 1.25 V is attained. Additionally, an indoor PCE of 38.7 is realized. Bothare among the best in their respective categories. Moreover, an all-perovskitetandem solar cell is configured, presenting a decent PCE of 23.2. This workemphasizes the significance of WBG PSCs for optoelectronic applications andindicates the eminent effects of SAMs for optimization of WBG PSCs.
