the latest methods and techniques for creating semitransparent perovskite solar cells: (i) utilizing thin perovskite film; (ii) self-assembling the perovskite on a photoanode to create an empty transparent area without sacrificing light-harvesting efficiency; (iii) utilizing solvent properties to form perovskite islands through surface dewetting; and (iv) creating a transparent contact to make the solar cell fully semitransparent. Semi-transparent PSCs use tunable perovskite layers for solar cells and building-integrated photovoltaics. The inverse relationship between transmittance and efficiency is a challenge. To overcome these challenges, numerous studies are underway, including those on band-gap tuning, high-performance charge transport layers and electrodes, and creating island-shaped microstructures.
