ABSTRACT:
This invention relates generally to the fabrication of heterojunction diodes from semiconducting (conjugated) polymers and acceptors such as, for example, fullerenes, particularly Buckminsterfullerenes, C.sub.60, and more particularly to the use of such heterojunction structures as photodiodes and as photovoltaic cells.
