【摘要】：以poly(3-hexylthiophene)(P3HT)作为电池给体材料,[6,6]-phenyl-C60-butyric acid methyl ester(PC61BM)为电池受体材料,使用Cs2CO3作为电池的阴极修饰层,通过测量不同条件下制备的器件的J-V曲线和转换效率,研究了Cs2CO3的厚度以及退火温度对电池器件性能的影响。结果表明在2000 r/min转速下旋涂Cs2CO3并在130℃温度下进行退火10 min,电池的短路电流、填充因子、转换效率分别提高到11.56 m A/cm2、58.28%、3.37%,与未处理的器件相比效率提高了16%,而且使用碳酸铯作为阴极缓冲层可以有效的提高电池的稳定性,延长器件的寿命。
[Abstract]:Poly (3-hexylthiopheneated) P3HT was used as the battery donor, and [6F6] -phenyl-C60-butyric acid methyl estern PC61BMM was used as the battery receptor material. Cs2CO3 was used as the cathode modification layer of the battery. The J-V curves and conversion efficiency of the devices prepared under different conditions were measured. The effects of the thickness of Cs2CO3 and annealing temperature on the performance of the battery are studied. The results showed that the short circuit current and filling factor of the battery were spin-coated with Cs2CO3 at 2000 r/min and annealed at 130 鈩，
