Hyun-Joong Kim & Kwang-Seok Jeong share their design of SIG (Self-Energy Converting Sunglasses). The idea is simple and brilliant, as we know sun glasses is made to protect our eyes from harmful sun rays, and why we don’t convert the rays into electrical energy. The SIG will integrate dye solar cell into the lenses of the glasses.

The dye solar cell is described by the designers of the SIG as “cheap organic dye [used with] nano technology [providing] cheap but high energy efficiency.” Inexpensive, light, and visible-ray penetrable. The lens turns sunlight rays, (rays that would otherwise harm the eye,) into electrical energy.
