Abstract Semi‐transparent perovskite solar cells (ST‐PSCs) are promising for their application in building integrated photovoltaics (BIPVs). For BIPVs, a light utilization efficiency (LUE) > 2.5 is required which multiplication of average visible transmittance (AVT) and power conversion (PCE). Generally, semitransparency achieved by reducing film thickness increases AVT but decreases PCE resulting lower LUE. Here, an interface engineering strategy employed on wide bandgap thin absorber layer to increase The study employs three different alkylamine hydrochlorides molecules with varied alkyl chain length, viz., 2‐chloroethylamine‐hydrochloride, 3‐chloropropylamine‐hydrochloride, 4‐chlorobutyalamine‐hydrochloride at perovskite/electron transport (ETL) investigates effect crystallization. Further, it demonstrated that can strongly interact suppress non‐radiative recombination facilitating charge the perovskite/ETL interface. Devices post‐treated interfacial layer, demonstrate higher LUE 3.45% (PCE 14.11%) ≈25% (400–800 nm), V oc 1.23 V. Moreover, unencapsulated devices retain ≈89% initial after storage 1500 h under relative humidity ≈35–40%. This provides efficient approach improve stability ST‐PSCs energy‐efficient smart windows.

The addition of organic cationic iodides to form low-dimensional perovskite is an essential strategy for defect passivation in solar cells (PSCs). Specially, the 2D/3D structure can combine stability 2D and high charge transport performance 3D perovskite. Here, we introduced phenylammonium hydroiodide salts with different alkyl chain lengths into PSCs precursor solution research influence on formation thin films photovoltaic PSCs. As a result, champion power conversion efficiency (PCE) was increased 22.68% by incorporation cation phenylpropyl ammonium iodide (PPAI) best length. We further fabricated modules (PSMs) aperture area 21 cm2, achieving impressive 21.65% excellent that maintaining 89% its initial after 1000 h maximum point tracking.
