Solar cells gain efficiency by emitting light in fewer directions

Solar cells absorb sunlight and convert it into electricity. This process, however, is not perfect, and a large part of the solar energy is simply lost along the way. Some of it is lost as heat, while photons with insufficient ...

Chemical fine-tuning lifts perovskite LEDs to 37% efficiency

Chemists developed a way to significantly improve the performance of light-emitting diodes (LEDs) made with perovskite. The journal Nature published the advancement in these hybrid LEDs, which hold potential for a range of ...
