Spain (TGW) – Researchers in Spain have developed a new material that can absorb infrared light, in contrast to today’s solar cells which only absorb visible light.
Because infrared light makes up half of the sun’s output that reaches the Earth, current solar cells that can only absorb visible light have a theoretical absorption limit of 40%, and only 30% in practice.
The new material, because it can capture both types of light, has a theoretical limit of 63%.
Researchers led by Perla Wahnon added titanium and vanadium into a conventional semiconductor, giving the material its special properties.
