QD Solar Cell

Quantum Materials’ subsidiary, Solterra Renewable Technologies Inc. is singularly positioned to lead the development of truly sustainable and cost-effective solar technology as the first company to introduce a new dimension of cost reduction by replacing silicon wafer based solar cells with low cost, highly efficient Quantum Dot based solar cells by proprietary roll-to-roll printing techniques invented by our CSO, Dr. Ghassan Jabbour.

THE PROBLEM

High energy costs, dependence on foreign oil, unstable governments, the threat of global warming and increased greenhouse gases; we know the problems but we have not done enough to solve them…until now.

Quantum Dot Solar cells can absorb energy 24/7. While common black silicon panels are best at absorbing visible light at the peak times of the day, QD Solar Cells can absorb power from the ultraviolet thru visible to the infrared lighting range to produce their power, day and night. The typical silicon wafer solar panel is power rated using sunlight at zenith (climax or high point) which provides a radiance of just over 1 kilowatt per square meter at sea level. This peak energy is a combination of 527 watts of infrared radiation (IR), 445 watts of visible light, and 32 watts of ultraviolet radiation (UV). The wafer type silicon solar cells available today can only process visible sunlight. That means over half of the energy available from IR and the remainder in the UV are not being absorbed so they can be converted to electricity. Instead these IR and UV light waves become detrimental thermo energy which further limits the absorption of silicon solar panels. 56% of the available energy to be converted to electricity is LOST using today’s solar cells.

THE SOLUTION

SOLAR ENERGY- no carbon emissions, unlimited supply and available to all. This renewable source is one of the answers to energy independence, but has been previously expensive to implement. Now, with advanced automated tetrapod quantum dot manufacturing, both cost and efficiency concerns are addressed. Although smaller than living cells, quantum.dots can absorb all wavelengths of visible sunlight plus the UV and Infrared. Using proprietary technologies, Solterra will manufacture very low cost solar cells utilizing Quantum Dot Technology for less than the cost of conventional solar cells. By combining Quantum Materials disruptive technologies of novel synthesis, thick shell coating and automated production, quantum dot supply problems are solved. Solterra will also use R2R production methods invented by QMC Chief Science Officer, Dr. Ghassan Jabbour, that can be scaled by increasing R2R speeds.

Our third generation quantum dot solar cells do not require custom made, expensive ,nor complex, processing equipment, and we do not use costly silicon or rare earth elements such as indium. Solterra instead will rely on low-cost screen printing and/or inkjet techniques applied to inexpensive substrates. Quantum Dot Solar Cells have extremely high potential efficiency, having demonstrated the production of multiple excitons from a single electron.

Quantum Materials patented quantum dot synthesis, developed by Dr. Michael Wong of Rice University has been acquired by Quantum Materials for Solterra Renewable Technologies, Inc. By combining this proprietary, low cost QD manufacture process with automation QD manufacture, the quantities of tetrapod quantum dots needed to supply the daily use requirements of a solar cell plant production can be scaled into the Gigawatts/year range reducing the cost of solar generated electricity to little more than grid price at today's electricity prices. With grid prices expected to continue to increase, renewable solar energy using QMC Quantum Dot Technology will not only cost less but can also be good for the environment!

Quantum Materials' Solar cells will come to market competitively priced with the opportunity to reduce prices even further as economies of scale come into effect. Additionally we believe our quantum dot manufacturing capability and print based cell manufacturing process will enable the rapid deployment of additional manufacturing sites across the globe.

Solterra Renewable Technologies, Inc., the wholly-owned subsidiary of QMC is developing Next-Gen QD Solar Cells printing by roll-to-roll processes.

Unique University - Industry Partnership to Spur Tetrapod Quantum Dot Commercialization

Quantum Materials Corp. and Texas State University signed an Industry -Academic Partnership in 2013. Texas State's Advanced Functional Materials Laboratory, outfitted with state-of-the-art characterization and analysis equipment will assist Quantum Materials' nearby Wet Labs in special projects designed to produce department scientific papers advancing tetrapod quantum dot research.
