Solar cells are one of the most attractive nonpolluting energy sources. In this field, hybrid and inorganic perovskite, which is a semiconductor, has been shown to function efficiently in solar cells. One of the unique properties of perovskite allows it to become semitransparent, and not just by controlling its optical properties. In this Focus Review we provide the most updated methods and techniques to make semitransparent perovskite solar cells: (i) the use of thin perovskite film; (ii) the possibility to self-assemble the perovskite on a photoanode, providing an empty transparent area while not sacrificing the light-harvesting efficiency; (iii) the use of solvent properties to form islands of perovskite using dewetting on the surface; and (iv) the possibility to form a transparent contact that makes the solar cell fully semitransparent. Finally, the potential and future features of semitransparent perovskite solar cells are presented.
