Abstract The combination of p‐type NiO x and self‐assembled monolayers (SAMs) has recently emerged as an optimal structure for hole transport layer (HTL) in wide‐bandgap perovskite solar cells (WBG PSCs). However, the unique requirements this cascade HTL system differ significantly from those neat . Specifically, tendency to agglomerate can lead poor film morphology inadequate interfacial contact with SAMs, resulting significant open‐circuit voltage ( V oc ) loss PSCs. Herein, these issues are addressed by incorporating sodium hexametaphosphate (SHMP) into ink. This approach enhances dispersibility nanoparticles, improving conductivity films through interactions between P = O P‐O groups Ni ions. Additionally, SHMP promotes better Me‐4PACz interface increasing number hydroxyl on uniform surface films. Consequently, a high power conversion efficiency (PCE) 21.02% is achieved WBG (1.79 eV) PSCs smallest relative 24.69%. encapsulated devices exhibit excellent stability under humidity elevated temperatures. Furthermore, when combined Sn‐Pb narrow‐bandgap perovskite, PCE 27.66% attained 2‐terminal tandem (TSCs).

Harmful defects are typically major performance and stability degrading factors in perovskite solar cells (PSCs). In order to prevent defect formation ion migration, some small molecule additives often used PSCs, which, however, highly volatile very likely drift. this work, an amphiphilic polymer, p(HEMA-co-DEAMA), is synthesized doped into organic salt solution. Through Lewis base coordination hydrogen bonding, it can be chemically bonded a perovskite. Further analysis reveals that trap density significantly reduced after simple treatment with suppressing charge recombination boosting the power conversion efficiency (PCE) of PSCs. Moreover, ordered long chain structure p(HEMA-co-DEAMA) forms gridlike crystal, which stitches grain boundaries thus modulates growth crystals therein. Importantly, exposure alkyl chains on also provides hydrophobic coating, protects film from environmental humidity further enhances operation stability. Therefore, unpackaged devices modified exhibit excellent retaining more than 90% original PCE when stored for 1000 h air environment, indicating viability our strategies.

Abstract CsPbI 2 Br perovskite solar cell (PSC) is a promising candidate for high‐efficiency single‐junction and tandem cells. However, due to the numerous surface defects of film mismatch energy levels at Br/charge transport layer interface, power conversion efficiency (PCE) PSC still significantly lower than theoretical limits. To alleviate those issues, in this work, carboxylate‐based p‐type polymer, TTC‐Cl, employed modify layer. TTC‐Cl can interact with uncoordinated Pb 2+ , thereby mitigating surficial reducing non‐radiative recombination losses. Furthermore, also improves band properties thin surface, rendering it more p‐type, which facilitates hole transport. Consequently, PSCs modification achieve remarkable PCE 17.81%, notably higher that counterpart without (15.87%). Moreover, exhibit better stability.
