Abstract Semi‐transparent solar cells represent an exciting opportunity for sustainable energy production, thanks to the possibility of being integrated into buildings and urban environments, effectively exploiting already existing space. Perovskite (PCSs) are ideal candidates, offering high power conversion efficiencies (PCEs) combined with a tuneable band gap adjustable thickness, which allow convenient modulation average visible transmittance (AVT). However, balancing PCE AVT is challenging target. This study uncovers that depositing perovskite layer based on Formamidinium Lead Iodide (FAPbI 3 ) thin films in ambient air, rather than nitrogen‐controlled atmosphere, allows increase value up > 40% while also enhancing photovoltaic performance stability. The optoelectronic quality as‐obtained substantially enhanced, showing fewer defects superior morphology. As result, air‐deposited devices exhibit higher efficiency, which, combines enhanced AVT, results champion device light use efficiency (LUE) 4.2%, having 13.8% 30.4%. record LUE deposited air conditions pave avenue toward real‐world application semi‐transparent PSCs.
