The Role of Kinetic Conditions on the Formation of a Perovskite Absorber in Increasing the Conversion Coefficients of Solar Cells
Abstract
The paper presents ways to improve the morphology and efficiency of perovskite solar cells synthesized from lead acetate trihydrate and methylammonium iodide. It was found that the quality of nanoscale films of the perovskite absorber depends on the time of precursor solution spinning and conditioning before annealing. The optimal combination of these times made it possible to increase the conversion coefficient and short-circuit current of perovskite solar cells to 10.97% and 18.7 mA/cm2, respectively. The results can be used to optimize the optoelectronic characteristics of perovskite depending on a number of kinetic parameters, such as the rotation speed, the acceleration time (acceleration) of the spin-coater, the temperature, and duration of annealing during the formation of solar cells.
