We’re fascinated by the deep blue, the con-trast of the glowing red points and the compelling graphic structure. This photo was taken on behalf of a car manufacturer and shows the structure of a solar cell, more specifically a panel made of polycrystalline silicon. What’s special about the material is that the silicon crystals consistently align themselves so that incident light is always optimally utilized. To make this visible to the human eye, we took a microphotograph (with polarized incident light) magnified by a factor of 160 times. With the help of scanning electron microscopy, we can take even more extreme close-ups, magnified by up to 100,000 times or even more.
