Tech Xplore / A solar cell moonlights as an LED, both absorbing and emitting light more efficiently

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor material can, in principle, ...
