The power conversion efficiency (PCE) of inverted lead-halide perovskite solar cells (PSCs) via vapor deposition has undergone significant enhancement through the incorporation a self-assembled monolayer (SAM) serving as hole transport layer. To achieve high-performance PSCs, SAM layer needs to maintain dense and high-coverage configuration during fabrication process. Our investigation revealed that solid-vapor reaction, conditions high temperature low pressure can potentially lead migration molecules, particularly those adsorbed on surface but have not yet formed covalent bonds. In this study, overcome limitation, we developed an impregnation process for mixed molecules with (4-(7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid (4PADCB) glycine hydrochloride (GH), which reduces agglomeration enhances their strong anchoring ability substrate, thereby maintaining extremely coverage rate even in high-temperature low-pressure environment reactions. Consequently, champion efficiencies 22.15% (0.16 cm2) 19.18% (5 cm × 5 module) are achieved, is highest record PSCs based deposition. Moreover, advantages reusability, good uniformity, cost, very broad commercial prospects.

Wide‐bandgap (WBG) perovskite films are vital for advancing high‐efficiency silicon/perovskite tandem technology. However, the performance of WBG produced using vapor deposition techniques often lags behind that solution‐based methods due to challenges in accurately controlling halide ions and crystallization quality, particularly Br/I ratio vapor‐deposited films. In this study, we investigated ion exchange (IE) process vapor‐solid reaction developed two producing CsFAPbI x Br 3− thin films: one involved reacting 3 FABr (I‐based IE perovskite), while other used CsFAPbBr FAI (Br‐based perovskite). Our findings demonstrate Br‐based exhibits superior quality lower defect density throughout process. As a result, approach has facilitated development solar cells with maximum power conversion efficiency 19.51%. Additionally, unencapsulated devices were able retain 88.9% their initial after being stored 1500 hr under atmospheric conditions (25°C, 18 ± 5% RH). This research provides novel strategy methodology fabricating high‐performance cell via vapor‐based techniques, which is crucial industrialization both cells.
