Photovoltaic Cell Performance Basics

August 19, 2013 - 4:55pm


Photovoltaic (PV), or solar cells use the energy in sunlight to produce electricity. However, the amount of electricity produced depends on the quality of the light available and the performance of the PV cell.

Researchers make measurements of conversion efficiency and quantum efficiency to characterize the performance of PV cells. Based on these results, researchers may redesign aspects of the cell—e.g., material compositions or thicknesses of layers—to improve performance.
