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.

Abstract The interface stability and non‐radiative recombination loss of the cathode greatly limit performance inverted perovskite solar cells (PSCs). Here, an efficient multifunctional anti‐corrosive modification strategy based on 2,2′‐(1,3‐phenylene)‐bis[5‐(4‐tert‐butylphenyl)‐1,3,4‐oxadiazole] (OXD‐7) is proposed to overcome issues. OXD‐7 molecules chemically coordinate Ag electrode form a stable complex film OXD7‐Ag, which suppresses halide ion migration thus enhances corrosion resistance as well. In addition, trap density film, PCBM/Ag interfaces contact, built‐in potential, moisture resistance, well unfavorable exciton dissociation elimination devices, are also improved with arrangement upon PCBM correspondingly device stability. Bidirectional ITO observed, suppressed by modification. high power conversion efficiency (PCE) 21.84% fill factor (≈84.63%) obtained via this strategy, one highest PCEs FFs solution‐process MAPbI 3 /PCBM heterojunctions.

Abstract Herein, we synthesized two donor‐acceptor (D‐A) type small organic molecules with self‐assembly properties, namely MPA‐BT‐BA and MPA‐2FBT‐BA, both containing a low acidity anchoring group, benzoic acid. After systematically investigation, it is found that, the fluorination, MPA‐2FBT‐BA demonstrates lower highest occupied molecular orbital (HOMO) energy level, higher hole mobility, hydrophobicity stronger interaction perovskite layer than that of MPA‐BT‐BA. As result, device based‐on displays better crystallization morphology larger grain size less non‐radiative recombination. Consequently, using as transport material achieved power conversion efficiency (PCE) 20.32 % remarkable stability. being kept in an N 2 glove box for 116 days, unsealed PSCs’ retained 93 its initial PCE.
