Quantum Dots at SEMICON West
LED and solar technologies have been making huge inroads into commercial applications over the past decade. Primarily these inroads have occurred through a slow, steady improvement in cost per watt and cost per lumen through continuous improvement of traditional semiconductor-based processes. These improvements are expected to progress at steady rates and probably be the dominant contributor to these markets over the coming decade. Yet with billions of dollars in VC and government funding over the past few years, I suspect there will be breakthrough developments on the horizon that will be a game-changer for both PV and solid state lighting.
One potential game changer is quantum dots.
Quantum dots, also known as nanocrystals, are a special class of semiconductor materials whose electrical conductivity can be greatly altered via an external stimulus (voltage, photon flux, etc). Quantum dots are unique because they are so small, ranging from 2-10 nanometers (10-50 atoms) in diameter. At these sizes materials behave differently, giving quantum dots unprecedented characteristics, enabling never before seen applications to science and technology.
Quantum dots semiconductor nanocrystals have been considered in a broad range of applications, from biological tagging to LEDs, laser diodes, and solar cells.
Quantum dots have been used on silicon substrates with a coating of nanocrystals. Recent research in experimenting with lead selenide (PbSe) semiconductor, as well as with cadmium telluride (CdTe) have been announced in quantum dots. Other materials are being researched as well
In solid state lighting and displays, a few years ago QD Vision announced technical success in making a proof-of-concept quantum dot display and demonstrated a bright emission in the visible and near infra-red region of the spectrum. Since that time they have making significant progress in developing commercial applications in solid state lighting.
During SEMICON West, Seth Coe-Sullivan, Ph.D, CTO and Co-Founder of QD Vision will give an update on their technology and how their Quantum Light platform is being applied to deliver step-change improvements in power efficiency and color quality in commercial lighting. The first products incorporating Quantum Light technology are LED lamps and fixtures that deliver savings in energy of up to 80%, excellent color quality, and lifetimes in excess of 50,000 hours.
An update on the important developments at QD Vision will be one of the highlights of “LED Day” at SEMICON West. I hope you can be there.
