Researchers in Japan and China have discovered some butterfly wings have tiny solar collectors. The scientists used mother nature's evolutionary brilliance to man-make more efficient solar cells. The research found that butterflies are far more efficient at collecting solar energy than similar man-made solar cells. So now the butterfly science can help produce dye-sensitized solar cells that would be up to 10% efficient. The sensitized cells were invented in Switzerland and even pre-butterfly were mlore efficient than traditional cell tech.
