摘要
使用绿色溶剂水溶解CsBr,以达到提高CsBr溶解度、简化CsPbBr_(3)钙钛矿太阳能电池(perovskite solar cells)制备工艺和提高薄膜质量的目的。结果表明,在停留时间为5 s、退火温度为250℃的条件下,旋涂1遍质量浓度为250 mg·mL^(-1)的CsBr水溶液所制备的电池性能最优,实现了1.64 V的最高开路电压(open circuit voltage,VOC),短路电流密度(short-circuit current,JSC)为7.55 mA·cm^(-2),填充因子(fill factor,FF)为85.46%,光电转换效率(photoelectric conversion efficiency,PCE)为10.51%。
The green solvent water was used to dissolve CsBr,to improve its solubility,simplify the preparation process of CsPbBr_(3) perovskite solar cells,and enhance the quality of thin films.The results showed that under the conditions of a residence time of 5 s and an annealing temperature of 250℃,the device prepared by spin coating a CsBr aqueous solution with a mass concentration of 250 mg·mL^(-1)had the best performance,achieving a maximum open circuit voltage(VOC)of 1.64 V,a short-circuit current density(JSC)of 7.55 mA·cm^(-2),a fill factor(FF)of 85.46%,and a photoelectric conversion efficiency(PCE)of 10.51%.
