title: Soluble copper phthalocyanine applied for organic solar cells.
abstract: A soluble derivative of copper phthalocyanine, that is 2,9,16,23-tetra carboxyl copper phthalocyanine (CuTCPc), is synthesized in this paper. The applications of CuTCPc as donor and interlayer materials in solar cell devices are investigated. The results demonstrate that when CuTCPc is used as a donor material, the performance of the device ITO/CuTCPc/PCBM/Al shows an open circuit voltage (V(OC)) of 0.54 V, a short circuit current (J(SC)) of 0.825 mA/cm2, a fill factor (FF) of 32.3% and the power conversion efficiency (nu) of 0.14%. When CuTCPc acts as an interlayer, the performance of the device ITO/CuTCPc/P3HT:PCBM/Al is improved: J(SC) increases to 3.12 mA/cm2, V(OC) increases to 0.59 V, FF increases to 33.8%, and the corresponding nu is 0.62%.
