Abstract
A bi-facial tandem solar cell and a method of making a non-toxic perovskite/inorganic thin-film tandem solar cell stable, having matching bandgaps and a hysteresis free design including the steps of depositing a textured oxide buffer layer on an inexpensive substrate, depositing a metal-inorganic film from a eutectic alloy on the buffer layer; and depositing perovskite elements on the metal-inorganic film, thus forming a perovskite layer based on a metal from the metal-inorganic film, incorporating the metal into the perovskite layer wherein said perovskite layer is stable, hysteresis-free, and has a bandgap that matches the bandgap of the metal-inorganic.
