smallmolecule 的开的电路电压(V OC ) 器官的太阳能电池(振荡) 能被做改进合适荧光灯染料进施主层。在这份报纸,当有在铜酞毒(CuPc ) 的不同 DCJTB 集中的振荡的掺杂物,和表演被学习, 4-(dicyanomethylene )-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB ) 被使用。结果证明有在 CuPc 的 50% DCJTB 的 OSC 的 V OC 增加了 15% ,与标准 CuPc/fullerene (C60 ) 设备的相比。V OC 的改进被归因于更低最高占据了分子轨道(人) 在 CuPc 比那在 DCJTB 铺平。另外,在 CuPc 和 C60 有低吸收度的地方,轻吸收紧张在 400 和 550 nm 之间被提高,导致一个宽广吸收系列。
The open circuit voltage (Voc) of small- molecule organic solar cells (OSCs) could be improved by doping suitable fluorescent dyes into the donor layers. In this paper, 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7- tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) was used as a dopant, and the performance of the OSCs with different DCJTB concentration in copper phthalocyanine (CuPc) was studied. The results showed that the Voc of the OSC with 50% of DCJTB in CuPc increased by 15%, compared with that of the standard CuPc/fullerene (C60) device. The enhancement of the Voc was attributed to the lower highest occupied molecular orbital (HOMO) level in the DCJTB than that in the CuPc. Also, the light absorption intensity is enhanced between 400 and 550nm, where CuPc and C6o have low absorbance, leading to a broad absorption spectrum.
