Figure 4. Box plots for the statistical analysis of J-V characteristics for all PSC devices produced with different combinations of HTLs and annealing conditions. All PSCs contain NiOx as the base-HTL. Plot labels contain the MAPbI3 annealing type, and any addition of HTL buffer layer. MeO-2PACz is abbreviated as SAM in this plot’s labels. PSC: Perovskite solar cell; HTLs: Hole transport layers;
