METHOD OF MAKING A GERMANIUM PEROVSKITE/GERMANUIUM THIN-FILM TANDEM SOLAR CELL

摘要

A method of making a non-toxic perovskite/inorganic thin-film tandem solar cell 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.

1. A method of making a germanium perovskite/crystalline germanium thin-film tandem solar cell comprising the steps of:
depositing a textured oxide buffer layer on glass, depositing a Sn—Ge film from a eutectic alloy on said buffer layer; and depositing perovskite elements on said Sn—Ge film, thus forming a perovskite layer based on said Ge from said Sn—Ge film, incorporating said Ge metal into said perovskite layer.
