CONCENTRATION PHOTOVOLTAICS
Converged PV, also known as CPV, focuses sunlight onto a solar cell using mirrors or lenses. By focusing sunlight on a small area, less PV material is needed. PV materials become more efficient as light is concentrated, so the highest overall efficiency is obtained with CPV cells and modules. However, it requires more expensive materials, manufacturing techniques, and the ability to track the sun’s motion, so demonstrating the necessary cost advantage over today’s high-volume silicon modules has now become problematic.
