Fullerenes on film According to Prashant Kamat of Notre Dame Radiation laboratory Notre Dame, Indiana, fullerenes are possible candidates for harvesting solar energy but past efforts have reported very low photocurrents (less than a microampere).

The discovery sheds a different light on a recent patent refusal.
