Researchers recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. They created special holograms that can be easily inserted into the solar panel package. This method can increase the amount of solar energy converted by the solar panel over the course of a year by about five percent.
The energy available from sunlight is 10,000 times more than what is needed to supply the world’s energy demands. Sunlight has two main properties that are useful in the design of renewable energy systems. The first is the amount power falling on a fixed area, like the ground or a person’s roof...
