Solar panels were designed to accumulate light and they are typically very dark in color. The reason for this is so they are more efficient. But the problem is that they look bad. An eyesore. To make it cooler looking, researchers from the University of Michigan have developed the world's first semi-transparent colored solar panels.

The colors weren't created by adding dyes or a film, but instead were produced by the mechanical structure of the solar cells themselves causing them to reflect different wavelengths depending on the thickness of the semiconductor layer.

Finally, solar panels that won't make your home look ugly. [University of Michigan]
