Tailoring multifunctional anions to inhibit methanol absorption on a CsPbBr3 quantum dot surface for highly efficient semi-transparent photovoltaics

A simple anion modification strategy was developed to inhibit MeOH absorption in CsPbBr3 QDs. The CsPbBr3 QD solar cell yielded a PCE of 7.04%, which is the highest PCE reported for CsPbBr3 QD solar cells to date.
