“…To observe the effect of Al doping on ZnO, AZO films were characterized. As shown in Figure S1, the Raman peaks of ZnO appeared at 380 and 437 cm –1 , which corresponded to the optical phonon E2H mode and the A1 (TO) multiphonon mode, respectively. , The intensity of the two Raman peaks decreased with the increase of the Al doping ratio, which indicated that the Al element was successfully doped into ZnO, thereby leading to the reduction of the Raman peak intensity of ZnO. The results were consistent with the results observed by other groups …”

The ZnO/CsPbBr3 heterojunction interface often has poor chemical stability, resulting in the low photovoltaic efficiency of the solar cell. Here, we reported a method to fabricate an electron transport layer (ETL) using an Al element-doped ZnO (AZO) sol to improve the interfacial defects of the ZnO/CsPbBr3 heterojunction. The results showed that the interfacial defects first decreased and then increased with the change of the Al element ratio from 0 to 10%. The device had the least interfacial defects by 7% (atomic ratio) Al doping into ZnO. A 1.27 V open-circuit voltage (V OC) and 6.25% photoelectric conversion efficiency (PCE) were achieved by 7% Al element doping into ZnO in a ZnO/CsPbBr3/carbon structure solar cell. Moreover, the interfacial defect distribution and carrier recombination mechanism of the device were, respectively, illustrated by a varying light intensity test and electrochemical impedance spectroscopy. This work showed that an Al-doped ZnO film prepared by a sol–gel method could significantly improve the performance of solar cells.
