Solar cells boost efficiency by emitting light in fewer directions

Original: Solar cells gain efficiency by emitting light in fewer directions

Researchers report that solar cells can become more efficient by controlling the directions in which they emit light. By limiting light emission to fewer directions, the cells trap more of the sunlight they absorb, improving overall conversion efficiency. The finding, covered by Tech Xplore, is drawing attention as a potential route to better photovoltaic performance without fundamentally new materials.

Why now: New efficiency improvements in solar technology are closely followed amid global interest in cheaper renewable energy.
