| titleOfInvention | A method for preparing double electron transport layer perovskite solar cells |
| abstract | Embodiments of the present invention provide that the present invention provides a method for preparing a high-performance perovskite solar cell using a double electron transport layer structure. The method comprises: preparing a double electron transport layer on fluorine-doped tin oxide transparent conductive glass; the double electron transport layer is an indium gallium zinc oxide thin film and a tin oxide thin film, and the preparation method of the IGZO thin film can be selected from magnetron Sputtering or solution spin coating, the layer thickness is 10-45nm; a layer of organic-inorganic hybrid perovskite structure FA 0.7 MA 0.2 Cs 0.1 Pb(Br 0.05 I 0.95 ) 3 is prepared as a light absorbing layer by solution spin coating; A layer of Spiro‑OMeTAD was prepared as a hole transport layer by solution spin coating; a gold electrode was vacuum evaporated. The above technical solution has the following beneficial effects: reducing carrier recombination inside the solar cell, promoting effective energy output, increasing the fill factor (FF) of the solar cell, and preparing a solar cell with high energy conversion efficiency. |
