New Solar Cell has Boosted Power, Reduced Heat, and Prolonged Life

Chicago (ToGW) – Placing a film of silicon nanoparticles onto a silicon solar cell can boost power, reduce heat and prolong the cell’s life, researchers now report.

"Integrating a high-quality film of silicon nanoparticles 1 nanometer in size directly onto silicon solar cells improves power performance by 60 percent in the ultraviolet range of the spectrum," said Munir Nayfeh, a physicist at the University of Illinois.

In other solar cells, ultraviolet light is filtered out or absorbed.

The improved performance is a result of enhanced voltage.
