| 摘 要： | 系统地研究了采用刮涂法制备聚合物薄膜太阳能电池时刮涂速度和基底温度对活性层厚度以及形貌的影响。当刮涂速度增加或者基底温度降低时,由于溶液粘度和表面张力的变化导致活性层厚度增加。与旋涂方法相比,刮涂方法制备的活性层薄膜具有更小的粗糙度和精细的相分离结构,从而减少了光伏电池的漏电流并提高了填充因子。利用刮涂方法制备的聚合物太阳能电池能量转换效率达到了4.2%。

| Abstract: | The poly(3-hexylthiophene):-phenyl C61-butyric acid methyl ester(P3HT∶PCBM) bulk-heterojunction polymer solar cells fabricated with doctor-blade coating were studied.It is found that the active layer thickness increases with increasing the coating speed or lowing substrate temperature,which is attributed to the changes of solution viscosity and surface tension.Moreover,the P3HT∶PCBM active layer produced by doctor-blade coating demonstrates fine donor-acceptor nanoscale phase separation favoring enhancing exciton dissociation and charge collection.A 4.2% P3HT∶PCBM solar cell was fabricated with doctor-blade coating technique. |
