Blade‐Coated Perovskite Indoor Photovoltaics Enabled by Solvent and Morphology Engineering

) achieve impressive efficiencies of 31.8% and 24.0%, respectively, under 1000 lux LED illumination (4000 K), retaining over 80% PCE of control devices fabricated by spin-coating and thermal evaporation. This work addresses the key challenges faced in scalable solution-processed perovskite IPV production, offering a pathway to transition from lab research to industrial production.
