| titleOfInvention | An organic small molecule interface modification material and its application and perovskite solar cells |
| abstract | The invention discloses an organic small molecule interface modification material and its application and a perovskite solar cell. Among them, the organic small molecule interface modification materials LS1, LS2 or LS3, the organic small molecule interface modification materials can modify the surface of nickel oxide through physical adsorption and chemical reaction, which can not only reduce the density of defect states on the surface of nickel oxide, but also inhibit the Ni oxide surface. 3+ OOH degrades perovskite, and at the same time, optimizing the energy level arrangement at the interface reduces the hole transport barrier at the interface, thereby improving the interface charge extraction of perovskite solar cell devices and reducing interface carrier recombination. In the p-i-n-type perovskite solar cells prepared with this material, the device performance is significantly improved. Among them, the surface of nickel oxide is modified with small molecule interface modification materials, and the device efficiency based on methylamine lead iodide perovskite photoactive layer system is increased from 20.17% to 21.15% and 21.12%. |
