In a world-first, researchers at the Universidad Complutense de Madrid in Spain have fabricated an intermediate band (IB) solar cell using gallium phosphide and titanium that could potentially deliver an energy conversion efficiency of 60 percent.
The solar cell could deliver this performance at a wavelength of 550 nm and above.
To harness energy from the brightest star in our skies, we have deployed solar cells that can convert sunlight into electric current. The silicon-based solar cell, however, can only harness a part of the sunlight incident on it, giving off the rest as heat.
