TiO2|CsPbBr3|m-c|GS as solar cell and photoanode. a Schematic illustration of the CsPbBr3 photoanode for PEC O2 evolution: TiO2|CsPbBr3|m-c|GS uses commercial conductive GS on the m-carbon layer; The photoanode is illuminated through the FTO glass. b Photovoltaic current density-voltage curves measured under simulated AM 1.5 G solar light (100 mW cm−2) before and after 2 h of immersion in water. Curves shown are measured in reverse scan. c Typical linear sweep voltammetry (LSV) measured under PEC conditions at a scan rate of 20 mV s−1, measured in 0.1 M KNO3 at pH 4.3, under continuous simulated AM 1.5 G solar illumination, 1 sun
