Paper 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 VOC = 0.85 V, JSC = 2.65 mA/cm2, FF = 0.42, and ηPext = 1%.
