Abstract
In this letter, an efficient subphthalocyanine (SubPc)/C60 heterojunction organic photovoltaic device was demonstrated. The power conversion efficiency was improved from 2.7% to 4.3% by the sublimation of SubPc. The atomic force microscopic images showed that the crystallinity was improved with the sublimation of the SubPc, leading to the significantly enhanced hole mobility of SubPc in orders of magnitude as estimated by the space-charge limited current. The external quantum efficiency spectra further confirmed the improved charge collection efficiency as a result of the increase in the hole mobility of SubPc due to the unchanged spectral shape over the entire spectrum.
