Abstract Inorganic perovskite solar cells (PSCs) suffer from serious carrier recombination and open‐circuit voltage loss because of surface defects unfavorable energy level alignment. Herein, a polylactic acid (PLA) modification approach to improve the performance mixed‐halide inorganic perovskites is reported. First, are effectively passivated through strong interaction between C═O in PLA undercoordinated Pb 2+ . Second, secondary grain growth induced by modification, resulting larger sizes. Third, makes region change n‐ p‐type, favoring charge transport hole layer (HTL). The modified films enable PSCs with less nonradiative lower loss. Consequently, record PCEs 19.12% 18.05% achieved for CsPbI 2.25 Br 0.75 2 PSCs, respectively. PSC an active area 1 cm shows PCE 16.41%. A 14.70% HTL‐free carbon electrode. In addition, significantly improved air stability due hydrophobic coating. This work suggests that effective achieving efficient, stable, scalable, low‐cost PSCs.

Abstract All–inorganic perovskite solar cells (PSCs), such as CsPbX 3 , have garnered considerable attention recently, they exhibit superior thermodynamic and optoelectronic stabilities compared to the organic–inorganic hybrid PSCs. However, power conversion efficiency (PCE) of PSCs is generally lower than that PSCs, contain higher defect densities at interface within light‐absorbing layers, resulting in non‐radiative recombination voltage loss. Consequently, regulation has been adopted an important strategy improve device performance stability.

Abstract The power conversion efficiency (PCE) of CsPbI 2 Br perovskite solar cells (PSCs) is still far from the theoretical due to pronounced losses in open‐circuit voltage ( V OC ). loss can be mitigated by employing an appropriate hole transport layer (HTL), which facilitates energy level alignment and minimizes interface recombination losses. In this work, two D‐π‐A type polymers are chosen, PE64 PE65, as HTLs, where pentacyclic dithieno[2,3‐d; 2′,3′‐d “]benzo[1,2‐b; 4,5‐b”]dithiophene (DTBDT) D‐unit quinoxaline (Qx) A‐unit. It demonstrated that polymer PE65 with chlorinated thiophene side chain on DTBDT unit has optimized molecular arrangement, improved matching, enhanced passivation Br, effectively reducing caused radiative non‐radiative PSCs. Finally, PSCs utilizing HTL achieve a 17.60% high 1.44 V. Furthermore, also employed construct inter‐connecting layers (ICLs) for tandem (TSCs).
