NASA funds fluorescent greenhouse roofing tech
Added on 09 December 2022
"Our UbiGro Inner product, which installs under the roof, has been popular with growers having shown great productivity enhancements, and now our team is excited to roll out a full-cover product, called UbiGro Cover," said Matt Bergren, Chief Product Officer at UbiQD. "The progress that we're making on extruded films is enabling a whole new class of products for the controlled environment agriculture industry."
UbiGro Cover utilizes a novel quantum dot (QD) polymer system developed by UbiQD that led to multiple orders of magnitude improved fluorescence sunlight durability. Historically, nanomaterials have struggled to survive the high temperatures needed for twin-screw compounding and blown film extrusion. These QD films maintain high light-conversion efficiency exceeding 90% over thousands of hours of accelerated aging. Plant trials are underway, and the benefits are expected to be as good or better than those seen with UbiGro Inner. The work builds on previous NASA funding, and may also benefit other applications, including solar.
