Abstract

Counter-intuitively, efficient external fluorescence is a necessity for achieving the highest possible solar cell efficiency. Why would a solar cell, which is intended to absorb light, benefit from emitting light? Although it is tempting to equate light emission with loss, paradoxically, light emission actually improves the opencircuit voltage, and the efficiency.
