US Patent 11287162 Solar power system using luminescent paint

An energy harvesting system is provided. The system includes a waveguide operable for trapping at least some light energy. The waveguide defines a surface and an edge. A photovoltaic cell is coupled to the surface or the edge of the waveguide. A waveguide redirecting material is provided on the surface of the waveguide. The waveguide redirecting material is formed of a solidified colored luminescent paint. The paint is configured to be applied and adhere to the surface of the waveguide and redirect light energy to the photovoltaic cell. A method of generating and demonstrating solar power using the system is also provided.
