DoE Says Quantum Dots, Fullerenes 'Pairs' Convert Light to Energy

Description Scientists at the U.S. Department of Energy's Brookhaven Lab have assembled nanoscale pairings of particles that show promise as miniaturized power sources. The particle 'pairs' are composed from light-absorbing colloidal quantum dots linked to carbon-based fullerene nanoparticles, researchers said. The pairings can convert light to electricity in a precisely controlled way.

"This is the first demonstration of a hybrid inorganic/organic, dimeric (two-particle) material that acts as an electron donor-bridge-acceptor system for converting light to electrical current," said Brookhaven physical chemist Mircea Cotlet, lead author of a paper describing the assembly method in the journal Angewandte Chemie.
