Another step forward for solar

Another day, another solar advancement. University of Illinois researcher Nayfeh reports that a silicon nanoparticle thin film will "boost power, reduce heat and prolong the cell’s life." Not too shabby.

The size of nanoparticle used affects the part of the spectrum that is absorbed. With 1 nanometer particles, even UV can be absorbed. In conventional cells the UV creates heat which damages the cell over time.

No word on when the group would try to commercialize this technology, or what the incremental cost might be.
