Solar Performance and Efficiency | Department of Energy

The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of energy.

How do solar cells work?

Artwork: How a simple, single-junction solar cell works. A solar cell is a sandwich of n-type silicon (blue) and p-type silicon (red). It generates electricity by using sunlight to make electrons hop across the junction between the different flavors of silicon: When sunlight shines on the cell, photons (light particles) bombard the upper surface.
