PbS quantum dot solar cells (QDSCs) have emerged as a promising low-cost, solution-processable energy harvesting device and demonstrated good air stability potential for large-scale commercial implementation. QDSCs achieved record certified efficiency of 12% in 2018 by utilizing an n+–n–p structure. However, the p-type layer has generally suffered from low carrier mobility due to organic ligand 1,2-ethanedithiol (EDT) that is used modify (QD) surface. The EDT naturally limits thickness...
