Sphelar is prettier and more efficient than flat solar cells

Energy systems


Where flat solar cells depend on angle to maximize how much energy they extract from sun, the Sphelar solar cell has an efficiency of nearly 20%, because it places 1mm ball-like solar cells in a flower-like pattern which can extract energy from all directions. It’s also thin, flexible and transparent enough that it could be placed on regular window glass, turning those monster skyscrapers self-sufficient. Its production process is also vastly more efficient than flat solar, making it cheaper and reducing silicon waste enormously. [GT]
