A stabilization effect of [60]fullerene in donor-acceptor organic solar cells

In this paper we compare the behavior of solar cells based on pure regioregular poly(3-hexylthiophene) with those in which the same polymer is blended with a functionalized fullerene, under continuous illumination. We found that the decay of both photocurrent and photovoltage signals with time is substantially reduced when the blend is used. (C) 2002 Elsevier Science B.V. All rights reserved.
