Effect of different spin-coated rates on performance of polymer solar cell

以聚3己基噻吩(P3HT)和[6,6]-phenyl-C61-butyric acid methyl ester(PCBM)为活性层材料制成聚合物太阳电池,通过控制活性层旋涂速率控制活性层厚度。从不同活性层厚度器件的吸收光谱、原子力及器件各项性能参数详细分析了不同活性层旋涂速率对太阳电池性能的影响。结果表明:旋涂速率为1 000 r/min时,电池具有最佳性能,光电转换效率最高为1.54%。

The polymer solar cell（PSC）taking poly 3？hexylthiophene（P3HT）and [6,6]？phenyl？C61？butyric acid methyl ester（PCBM）as its active layer materials was made by controlling spin？coating rate of active layer. The influence of the spin？coating rate of different active layers on performance of the polymer solar cell is analyzed on the basis of absorbance spectrum, atomic force and other parameters of components with different thickness active layers. The results show that PSCs can achieve the best performance（power conversion efficiency（PCE）=1.54%）when the spin？coating rate is 1000 r/min.
