Backsheet manufacturer Tomark-Worthen LLC has developed a new polyamide backsheet under the U.S. Department of Energy’s Sunshot initiative. The product is based on a novel polyamide-ionomer alloy created by U.S. chemicals producer Dow. The alloy, as well as the other materials in the backsheet, are stabilized with a UV/anti-oxidant package that slows down the damaging effects of ultraviolet radiation. The manufacturer claims that the backsheet is 25-30% more affordable than high-efficiency fluoropolymer products.
A team from the University of Michigan in the U.S. has developed an organic tandem solar cell with 15% efficiency, a new record for an organic solar cell. The scientists utilized a novel method for stacking the two layers on top of each other without damaging either layer.
The funding is for 48 identified solar projects spanning two SunShot programs designed to advance solar power technologies in the U.S.
In the past eight years under President Obama, the solar industry has advanced from a tiny niche market to the country’s largest energy employer – though more work remains to be done.
