Luminescent solar concentrator

A luminescent solar concentrator is a type of solar panel. It captures solar energy and then reflects it, so it can be more easily captured and used. It looks like a sheet of clear plastic with tiny bright cubes inside. These cubes absorb the sunlight and then turn it into very bright colors. The colors then reflect off the sheet, concentrating the solar energy into one spot, which can be used to generate electricity.
