| titleOfInvention | Preparation method of tin dioxide/metal sulfide composite electron transport layer and its application in perovskite solar cells |
| abstract | The invention discloses a preparation method of a tin dioxide/metal sulfide composite electron transport layer and its application in a perovskite solar cell. Specifically, when the tin dioxide is prepared, a corresponding metal salt and a sulfur source are added to the precursor solution. compound, one-step in-situ compounding to obtain a tin dioxide/metal sulfide solution, which is then spin-coated on conductive glass and subjected to low-temperature annealing to obtain a composite electron transport layer, followed by deposition of a perovskite layer, and blade-coated carbon electrodes to assemble the perovskite Solar battery. When preparing tin dioxide, the invention can in-situ composite metal sulfide, which can passivate the defect state of tin dioxide to increase its electron mobility, adjust its energy band structure and introduce intermediate energy levels to improve the energy level of perovskite. The matching property can also increase the interface contact with the perovskite layer and reduce the interface defects, and realize the preparation of efficient and stable perovskite solar cells. The invention has the advantages of simple preparation process, mild reaction conditions, low cost, easy popularization and commercial application prospect. |
