According to this study, SnO2@CdCO3and SnO2/SnO2@CdCO3 performs as dual electron transporting layers for CsPbBr3 based perovskite solar cell. The fabricated PSCs with architecture of FTO/SnO2/ SnO2@CdCO3/CsPbBr3/C showed a Voc of 0.84 V, Jsc of 12.30 mA cmi 2, PCE of 6.67 % and FF of 0.64 are obtained at ambient condition.PDFTin oxideDual electron transport layerPSCsSolar energy materialsNanocompositesInvestigation on rod like SnO2@CdCO3 nanocomposite-based electron transport layer for CsPbBr3 heterojunction perovskite solar cell applications brArtÃculohttp://dx.doi.org/10.1016/j.matlet.2022.133396
