Sigma-Aldrich through its Aldrich Materials Science business, said it was distributing Nanosys-created silicon nanowires to the global scientific research community. According to Sigma-Aldrich the fabrication of nanowires is challenging, so the supply deal is intended to further foster the development of a variety of new high-technology applications that can continue to open up exciting end product markets. Nanosys recently entered into a partnership with Samsung Electronics to develop products using Nanosys technologies for both solar and other electronics applications.

“Architected and synthesized at the atomic level, our materials deliver exponential improvements in efficiency and performance,” noted Jason Hartlove, CEO of Nanosys. “This new distribution agreement with Sigma-Aldrich puts our technology directly into the hands of researchers who are doing exciting work in labs around the world, driving the use of architected material solutions in a new generation of markets and applications.”

Nanosys silicon nanowires, which demonstrate semiconductor properties, are comprised of single crystal silicon grown using the vapor liquid solid (VLS) process.

According to Sigma-Aldrich, research already conducted in early 2010 found that fabricating thin films from ordered arrays of vertical silicon nanowires significantly increased the light-trapping properties in solar cells.

The solar tracker market continues to mature at breakneck speed, with designs and component selections becoming ever-more complex in the pursuit of better project economics. But a more simplistic design could deliver a triple benefit of lower Capex, EPC and Opex costs. This webinar will set out the ideal single axis tracker design for utility-scale solar farms. The design leapfrogs from decades of experience, with a comprehensive understanding and attention to the three cost structures of Capex, EPC and Opx. Sun and Steel Solar has prototyped a single axis tracker designed to deliver up to US$0.03/W in real savings compared to existing single axis trackers on the market. That’s US$30 million for every gigawatt deployed.

The 10th edition of the famous Metallization and Interconnection Workshop, MIW2021, will take place in the Thor Central venue in Genk, Belgium, on Monday, November 15, and Tuesday, November 16, 2021 as a face-to-face meeting. We are longing for direct exchange of knowledge and ideas after a long time. Hopefully you can be part of it! But of course, the organizors will keep an eye on the evolution of the Covid pandemic. It will be assess carefully, whether the workshop can be held without major risks or excessive restrictions. We are looking forward to exciting talks, discussions and meetings and to welcoming you in Genk!
