A [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) self-assembled monolayer (SAM) has been employed in perovskite devices demonstrating high efficiencies. However, a uniform layer does not form due to the hydrophobicity of Me-4PACz. Here, we tackle this challenge by adding conjugated polyelectrolyte, poly(9,9-bis(3′-(N,N-dimethyl)-N-ethylammonium-propyl-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)) dibromide (PFN-Br), Me-4PACz specific ratio, defined as Pz:PFN. With mixing engineering strategy using Pz:PFN, PFN-Br interaction with A-site cation is confirmed via solution-state nuclear magnetic resonance studies. The narrow full widths at half-maxima diffraction peaks and photoluminescence spectra films reveal improved crystallization optimal ratio Interestingly, additionally tunes work function built-in voltage solar cells. Devices employing optimized Pz:PFN deliver an open-circuit 1.16 V efficiency >20% for perovskites bandgap 1.6 eV reproducibility concomitant stability.
