Through van der Waals integration of Ag/Au electrodes onto single-crystal CsPbBr3 thin films and subsequent formation of Ag2O/CsPbBr3 bulk heterojunctions, effective interfacial hole doping is achieved, reducing the contact resistance by two orders of magnitude compared with previously reported contacts of similar composition.
