The invention is a perovskite solar cell based on a cellulose-modified hole-transporting layer. There are five functional layers sandwiched between the lower transparent electrode and the upper electrode layer. The hole transport layer, the cellulose interface modification layer, the perovskite active layer and the electron transport layer, and the buffer layer are in sequence, and the hole transport layer, the cellulose interface modification layer, the perovskite active layer and the electron transport layer are all The film was prepared by a low-temperature solution method. In the present invention, a thin layer of cellulose film is added between the air-blood transport layer and the perovskite active layer of the perovskite solar cell. The cellulose can improve the surface wettability of nickel oxide, and it is easy to form a continuous and uniform perovskite film. The photoelectric conversion efficiency of titanium ore solar cells has increased from 12.52 to 13.37, an increase of 6.8%, with good repeatability and low cost, and has broad application prospects. |
