Bandgap Engineering, a developer of silicon nanowire products, says it has secured a pair of patents representing breakthroughs in solar energy conversion efficiency and cost.
The first new patent covers technology to improve the performance of solar cells by placing scattering centers in volume around the nanomaterial. The resulting composite absorbs more of the incident light for energy conversion, according to Bandgap Engineering.
The second patent exploits nanowire/matrix interfaces and nano-engineers the band structure of silicon to optimize silicon for solar energy conversion. Research that led to both patents was led by Dr. Marcie Black, founder and chief technology officer of Bandgap Engineering.
