| titleOfInvention | A method for preparing double-layer perovskite light-absorbing layer |
| abstract | A method for preparing a double-layer perovskite light absorption layer belongs to the field of solar cells. The method includes the following steps: 1) preparing an electron transport layer on a substrate; 2) dripping light-absorbing layer precursors A and B on the surfaces of the substrates A and B with the electron-transporting layer, respectively, and spin-coating to obtain the perovskite light-absorbing layers A and B. B; 3) Invert the substrate with the light-absorbing layer A on the substrate with the light-absorbing layer B, so that the light-absorbing layer A and the light-absorbing layer B are closely attached together, and then perform annealing treatment; 4) After the annealing is completed, remove the Substrate A with an electron transport layer is a double-layer perovskite light absorbing layer. By preparing a double-layer perovskite light-absorbing layer, the invention makes the perovskite light-absorbing layer and the electron/hole transport layer form better interface contact to achieve the purpose of interface energy level matching, and at the same time increases the perovskite to water and oxygen. stability, thereby effectively improving the performance of perovskite solar cells. |
