摘要
对ITO/CuPc(15nm)/Rubrene(x%):CuPc:C60(1:1)/C60(30nm)/A1(100nm)结构的小分子有机太阳能中活性层I层厚度以及掺杂不同浓度红荧烯(Rubrene)材料对电池的制作工艺和性能影响进行了研究。实验结果表明:在有机太阳能电池的活性层厚度为20nm,掺入浓度为40%的红荧烯材料中电池的短路电流密度增加了42.1%,开路电压提高了13.3%,填充因子为0.31,能量转换效率增加了39.9%。表明红荧烯在460~530nm波段对光子更为有效吸收,且能增加更多有效激子的形成,从而使有机光伏器件的性能得到显著提升。
In this paper, the ITO/CuPc (15nm) /Rubrene (x%): CuPc:C60 (1:1) /C60 (30 nm) / A1 (100nm) of small molecular organic solar structure, active layer with the I layer's thickness and doped with different concentration of rubrene (Rubrene) effects of material process and performance of battery are studied. The experimental results show that:when the thickness of active layer in organic solar cell is 20 nm, and the incorporation of the concentration of rubrene material is 40%, the short-circuit current density of cells increases by 42.1% ,and the open-circuit voltage increases by 13.3%, and the fill factor is 0.31 ;the energy conversion efficiency is increases by 39.9%. Whereby showing that rubrene in the 460-530nm band has the effective photon absorption so as to be able to increase more effective exciton formation in such a way that the performance of organic photovoltaic devices can be significantly im- proved.
