The development of Black Silicon could increase PV efficiency by between 100 and 500%, perhaps even reaching the theoretical maximum efficiency of 30-40% conversion of light to energy.
Developed in secret at Harvard the technology creates a cone like texture on the surface of the silicon by zapping the surface with an intense short spectrum laser in the presence of sulfur hexafluoride gas. This textured structure allows absorption of light from all angles, as well as the infrared spectrum which greatly increases efficiency for a minimal cost increase to manufacturing. The rights to the technology belong to a new start up company SiOnyx.
Hopefully this can be commercialized in a timely and cost effective manner, something many other breakthroughs have failed at.Recommend this Post
