How much percent can CPVs (Concentrated Photovoltaic cells) convert solar energy into electrical energy?

Homework Equations

The Attempt at a Solution

According to this page, "http://www.benefits-of-recycling.com/solarenergycars-2/ ",
20% of solar energy is converted into electrical through normal solar panels but I'm wondering how much would CPVs increase the amount of current generated? It can be a general answer.

Have you tried looking up "CPV efficiency" or finding a manufacturer of CPVs and reading the specs?
