Abstract:

The organic solar cells with structure as ITO/PEDOT: PSS/P3HT + PCBM/LiF/Al are prepared to study the effect of annealing treatment on the property of battery. These devices are treated at 150 益for 60 min in an ambient atmosphere and the best power conversion efficiency(ηp)of 2.01% is obtained at an open circuit voltage(Voc)of 0.57 V,a short circuit current density(Jsc)of 6.32 mA·cm-2,and a fill factor(FF)of 0.55. The device performance is significantly improved by thermal annealing. At last, the internal cause of annealing affecting the property of battery is discussed.

Key words: organic solar cells, annealing, bulk heterojunction, photoelectric conversion efficiency
