A Study of the Effect of Doping Rubrene on the Performance of Organic Solar Cells

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.
