Nanotechnology Enables Solar Power Advances in 2010 & 2011
Bo Varga
Managing Director, Silicon Valley Nano Ventures

This July, 2011 nano + solar column focuses on emerging & advanced solar technologies including the emerging global R&D role of KAUST in Saudi Arabia, as well as several recent announcements in advanced quantum dot & quantum well technologies & the printing of CIGS type solar cells. My focus is on the business value of technology including manufacturing and application breakthroughs & not on deep technology. Read the Whole Article

New Nano Solar Developments in 2009
Bo Varga
Managing Director, Silicon Valley Nano Ventures

Nanotechnology can reduce costs, increase performance, and lower the environmental impacts of solar PV and CSP. Every month I read about nanotechnology impacts on solar photovoltaics and talk with start up / early stage companies and I am amazed and impressed by the many different and interesting research projects that report results. And by many new commercialization efforts, although I am often under NDA and cannot discuss those.

This column reports on a few developments over the last year with a particular focus on the increasing interest in nanocrystalline-based solar cells and on the use of Schottky barrier/junction approaches to increase solar cell efficiency. As well as on the use of Schottky junctions to replace p:n type solar cells with "perfect diode" based solar cells.

Nano Solar News: Global Warming & 2015 Cost Trends
Bo Varga
Managing Director, Silicon Valley Nano Ventures

The fundamental driver for solar PV & solar thermal is the efficiency & cost of conversion of sunlight to electricity or to heat. The competition is either fossil fuels or nuclear energy. Nuclear is high risk due to terrorism, waste products, "not in my backyard". Fossil fuels depend on the "carbon subsidy" - current prices do not including payment for global warming & the destruction of the biosphere. Solar growth at 20% per year for 50 years can replace fossil fuels & nuclear and remove the causes of global warming. Read the Whole Article
