| titleOfInvention | A method for preparing high-efficiency perovskite solar cells by introducing sulfide additives |
| abstract | A method for preparing high-efficiency perovskite solar cells by introducing sulfide additives belongs to the field of nano-functional device photovoltaic solar cells. The structure of perovskite solar cells is a mesoporous structure: a conductive substrate, a semiconducting oxide transport layer, a mesoporous layer, an organic-inorganic hybrid perovskite layer, a hole transport layer, and a metal counter electrode. In the present invention, an appropriate amount of sulfide additives are introduced into the perovskite light absorbing layer of methylamine lead iodide (MAPbI 3 ) and ternary cations (Cs 0.06 FA 0.79 MA 0.15 Pb(I 0.85 Br 0.15 ) 3 ) to regulate the growth process thereof. The construction of high-efficiency perovskite solar cells is realized, the crystal quality of the perovskite light-absorbing layer and the lifetime of photogenerated carriers of the perovskite film are improved, and the internal defects are reduced. For the battery constructed from the treated perovskite film, various electrical performance parameters of the device are improved, and the final performance is improved. The additive-assisted growth method is simple in process and low in cost, helps to improve the optical properties and stability of perovskite photovoltaic devices, and has good application prospects. |
