▎ 摘　　要

NOVELTY - Double-sided light-receiving solar cell comprises a transparent conductive substrate (1), first transmission layer (2), wide band gap perovskite layer (3), second transmission layer (4), tunneling composite layer (5), and second transmission layer, from the light-receiving front to the light-receiving back, three transmission layers, narrow band gap perovskite layer, fourth transmission layer, buffer layer, transparent conductive layer and back gate electrode. USE - Double-sided light-receiving solar cell used in solar power generation (claimed). ADVANTAGE - The battery effectively combines advantages of perovskite/perovskite laminated solar cell and double-faced battery so as to obviously improve short circuit current density of the battery, thus realizing higher photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a double-sided light-receiving solar cell, which involves: (A) taking transparent conductive substrate, and preparing a first transmission layer on the transparent conductive substrate; (B) depositing a layer of wide band gap perovskite on the first transmission layer to obtain a wide band gap perovskite layer; (C) preparing a second transmission layer on the wide band gap perovskite layer; (D) preparing a tunnel composite layer on the second transmission layer, preparing a third transmission layer on the tunnel composite layer; (E) depositing a layer of narrow band gap perovskite on the third transmission layer to obtain a narrow band gap perovskite layer; (F) preparing fourth transmission layer on the narrow band gap perovskite layer; (G) preparing a buffer layer on the fourth transmission layer; and (H) preparing transparent conductive layer on the buffer layer and arranging back grid electrode on the transparent conductive layer to obtain product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a solar cell.
