“Quantum dots or nanocrystals are the cutting edge of PV. They are tiny crystals just a few nanometers wide, and are capable of extracting two to three electrons for each photon absorbed. This allows for a massive leap in theoretically achievable efficiency over existing technologies—up to 60%, although current quantum dot cells have efficiencies far below this. In addition, they would be much cheaper to incorporate into solar cells compared with large crystalline sheets of silicon, and would offer high mechanical flexibility.” – Goldman Sachs, July 2008 Guide to Understanding Solar
Technology
Overview
QD Soleil has developed and consolidated a range technologies for use in photovolatics, including: the use of spectrum capture enhancers such as quantum dots; nanoparticle scatterers and light capture materials; semiconducting inks; and materials for dual nanocrystal and hybrid nanocrystal/polymer designs. Additionally, many 3rd generation solar designs inherently involve the use of nanomaterials, giving QD Soleil a broad fundamental position in this market. This technology is valuable to a range of industry participants including: solar equipment suppliers; solar material producers; glass and plastic manufacturers; thin film and amorphous silicon producers; and, of course, incumbent and new solar entrants. Many aspects of the technology are well developed and demonstrated. Much of the technology base is already exploited by Nanosys for commercial products including light emitting diodes, flash memory devices, and other opto-electric devices that usetransistor inks. As a result, QD Soleil has accumulated hundreds of man years of associated know-how.
The core of this technology was invented and protected prior to the broad commercial interest in nanotechnology for photovoltaics. This foundation offers any partner strategic leverage and a potential blocking position with respect to other companies in the field, allowing the partner to shape the solar ecosystem to its advantage. Below are links to current disruptive technologies and applications with broad commercial interest.
