Accidental finding could lead to full-spectrum solar cell

Researchers have found that the electrical properties of the semiconductor indium nitride are different from what been previously thought — by a wide margin. The result is that an alloy incorporating the material can convert virtually the full spectrum of sunlight — from the near infrared to the far ultraviolet — to electrical current. “It’s as if nature designed this material on purpose to match the solar spectrum,” said one researcher involved.
