| description | A method of bandgap tuning of co-evaporated perovskite by a solution process is provided. The method may include providing a co-evaporated perovskite, and treating a surface of the co-evaporated perovskite with a halide-based solution to diffuse the halide-based solution into the co-evaporated perovskite thereby doping it with a halide dopant to form a doped co-evaporated perovskite, wherein the doped co-evaporated perovskite has a characteristic bandgap that is shifted towards a smaller wavelength as compared to the characteristic bandgap of the co-evaporated perovskite before the doping. A doped co-evaporated perovskite having a tuned bandgap, and a solar cell including the doped co-evaporated perovskite is also provided.
L'invention concerne un procédé d'accord de bande interdite de pérovskite co-évaporée par un processus en solution. Le procédé peut consister à utiliser une pérovskite co-évaporée, et à traiter une surface de la pérovskite co-évaporée avec une solution à base d'halogénure pour diffuser la solution à base d'halogénure dans la pérovskite co-évaporée, ce qui la dope avec un dopant halogénure pour former une pérovskite co-évaporée dopée, la pérovskite co-évaporée dopée ayant une bande interdite caractéristique qui est décalée vers une longueur d'onde inférieure par rapport à la bande interdite caractéristique de la pérovskite co-évaporée avant le dopage. L'invention concerne également une pérovskite co-évaporée dopée ayant une bande interdite accordée, et une cellule solaire comprenant la pérovskite co-évaporée dopée. |
