A solar cell's energy conversion efficiency (О·, "eta"), is the percentage

Efficiency of Silicon Solar Cells Climbs Japanese materials company prototypes a 26.3 percent efficient silicon cell, steps away from the 29 percent theoretical maximum Solar cell efficiency The efficiency of a solar cell (sometimes known as the power conversion efficiency, or PCE, and also often abbreviated О·) represents the ratio where the

4.8. Solar cells Solar cells are -i-n photodiodes, which are operated under forward bias. The intention is top convert the incoming optical power into electrical power with maximum efficiency Cell Efficiency, on the other hand, refers to a single solar cell, or the small square/rectangles your solar panel is made up of (standard panels have anywhere from 60 to 96 cells). Overall Module Efficiency will always be lower than Cell Efficiency, due to the spaces between individual cells.
