Stanford University scientists were inspired by insect eyes in their development of a new design for a solar panel cell. The cells have a delicate photovoltaic material referred to as perovskite that is not damaged when it is exposed to heat, mechanical stress or moisture.
Researchers tested the material to see if it could withstand high temperatures on rooftops by exposing the perovskite cells to 185 degrees Fahrenheit and 85% relative humidity over a 6 week period. The solar panel cell was still capable of generating electricity at a highly efficient rate. Modeled after bug eyes, the compound solar cell is comprised of "a vast honeycomb of perovskite microcells, each encapsulated in a hexagon-shaped scaffold just 0.02 inches wide" according to SpringWise.
