After analyzing the structure of leaves, researchers at Princeton University created solar cells containing the same wrinkles and folds found in nature’s photon receptors that generate 47 percent more electricity than other solar cells. The wrinkles in the cells channel more solar energy into the cell, increasing absorption. The wrinkles also give the cells flexibility, increasing their lifespan as they won’t break as easily from bending. This expands the application potential for solar cells, opening the door to solar energy fabrics, windows and walls.
