| titleOfInvention | A solar cell and a method for preparing the same and a method for improving light absorption and transmission characteristics of a tin-based perovskite layer |
| abstract | The invention discloses a solar cell, a preparation method thereof, and a method for improving the light absorption and transmission characteristics of a tin-based perovskite layer. The tin-based perovskite precursor solution was fully blended, annealed and cleaned to obtain a tin-based perovskite layer film with a bulk heterojunction structure, and a solar cell was prepared based on this. The invention utilizes the low symmetry of the small molecule acceptor to increase its solubility in organic solvents, and meanwhile the small molecule acceptor has a suitable energy level and light absorption ability in the long-wave direction, which obviously improves its light absorption characteristics and transmission characteristics, and solves the problem. The problems of insufficient photoresponse and low open circuit voltage in the near-infrared region of traditional tin-based perovskite solar cells are solved; through practical verification, the conversion efficiency of the solar cell device prepared by the present invention is improved by more than 20% compared with the prior art, which can fully meet the commercial requirements of the device. needs for use. |
