A novel carbonate-based nanocomposite synthesized by hydrothermal technique for planar perovskite solar cells (PPSCs) applications. 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 cm−2, PCE of 6.67 % and FF of 0.64 are obtained at ambient condition.
- Dual electron transport layer
- Solar energy materials
