The need for cheaper and more efficient solar cells is huge.

Maybe this research will further our ability to harvest the sun like in making more efficient solar cells.

It seeks new materials for more efficient solar cells.

"We're not trying to make a more efficient solar cell in the next six months," Holten cautions.

Research continues into ways to make the actual solar collecting cells less expensive and more efficient.

Honda is building a $13.5 million factory to produce these highly efficient cells (news story Jan. 22).

It can be used for such tasks as designing more efficient solar cells for use in space.

If it is 10% efficient cells produced for very cheap, that could be a big step forward.

Sunseeker 95 was modified with a new array panel and more efficient solar cells.

Materials for efficient solar cells must have characteristics matched to the spectrum of available light.
