advance in solar cell physics

“ ....experimentally demonstrated a phenomenon in which semiconductor nanocrystals respond to photons by producing multiple electrons. The innovation has potential applications in a new generation of solar cells that would produce as much as 35 percent more electrical output than current solar cells.”

“Although the Los Alamos scientists have not yet built a working PbSe nanocrystal solar cell, they are the first to demonstrate the ability to use impact ionization to generate more excitons and hence a greater electrical current in the solar cell configuration......”
