Abstract

We investigate the dependence of the photovoltaic characteristics of organic photocells on the relative concentration of the donor-acceptor molecular complex. The devices were fabricated using a new [MEH-PPV] - co - [phenylene vinylene] blend with C₆₀. We find that the morphology and device performance are strongly influenced by the molar fraction (x) of C₆₀ in the electroactive layer of the device. The best device was obtained with x = 0.6 and manifested V_OC = 0.85 V, J_SC = 2.65 mA/cm², FF = 0.42, and η^P_ext = 1%.
