  • AbstractPerovskite solar cells with a planar p-i-n device structure offer easy processability at low temperatures, suitable for roll-to-roll fabrication on flexible substrates. Herein we investigate different hole transport layers (solution processed \(NiO_x\), sputtered \(NiO_x\), PEDOT:PSS) in planar p-i-n perovskite solar cells using the triple cation lead halide perovskite \(Cs_{0.08}(MA_{0.17}FA_{0.83})_{0.92}Pb(I_{0.83}Br_{0.17})^3\) as absorber layer. Overall, reproducible solar cell performances with power conversion efficiencies up to 12.8% were obtained using solution processed NiOx as hole transport layer in the devices. Compared to that, devices with PEDOT:PSS as hole transport layer yield efficiencies of approx. 8.4%. Further improvement of the fill factor was achieved by the use of an additional zinc oxide nanoparticle layer between the PC60BM film and the Ag electrode.
