Scientists at the Massachusetts Institute of Technology have developed a device they say could “turbocharge” a single-junction silicon PV cell, pushing the technology beyond its theoretical limit to efficiencies of 35% and higher.
Scientists at the Georgia Institute of Technology in the U.S. used x-ray imaging to observe cracks forming in a solid state lithium battery, a discovery they say changes the understanding of performance of solid state batteries and which could lead to more durable systems.
Scientists at the Massachusetts Institute of Technology have developed an accelerated process for screening new perovskite compounds as they search for those with the potential to be used in high efficiency solar cells. According to MIT, the process speeds up the synthesis and analysis of new compounds by a factor of ten and has already highlighted two sets of materials worthy of further study.
Researchers at Stanford University have developed a type of electrode which is highly resistant to salt corrosion, therefore allowing them to produce hydrogen using seawater. Applied at a larger scale, this development could potentially cut the cost of power-to-gas applications by greatly increasing the amount of water available.
REC Silicon has revealed plans to halt operations at its Moses Lake facility in 17 days’ time. The company says it has taken the decision to maintain liquidity for its semiconductor business with American workers set to pay the price for President Trump’s trade war with China.
Germany’s Fraunhofer Institute for Solar Energy (ISE) has set a new world record for PV module efficiency. Scientists at the institute achieved 41.4% efficiency for a solar module using both tandem cell and high-concentration PV technology.
Zinc battery specialist NantEnergy has acquired the U.S. energy systems and services business from Japanese electronics giant Sharp. The acquisition, according to NantEnergy will provide the company an important foothold in the U.S. market, and allow it to provide ‘energy as a service’ business models, using its Zinc-air battery, in multiple markets.
Revenue for the polysilicon maker’s solar materials segment fell almost 70% on the previous quarter, and the company reports its Moses Lake, Washington facility is running at only 25% capacity.
