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.
Australian and Indian scientists have developed a method of manufacturing soluble graphene in a cost-effective and eco-friendly way from one of Australia’s most common resources, gum trees.
With concern rising about future solar waste in India, research by the University of New South Wales has examined the economic barriers, technologies and opportunities offered by recycling end-of-life silicon PV modules.
The addition of either salt enables more even distribution of halide atoms within the perovskite material – key to increasing cell conversion efficiency. The explanation should speed up the process of identifying the best perovskite mixes.
Dutch researchers have come up with a system they claim has a maximum estimation error of less than 10% and which reduces the computational requirements for calculating the output of PV systems in complex environments. The approach is based on the correlation between a skyline’s profile and annual irradiation.
Bifacial solar panel performance has become such a hot topic there are now at least four competing field test sites ramping up in the United States, each matching a different set of trackers and panels. DNV GL, Soltec, NREL and Sandia are all involved, and initial results are expected this year, once a year’s data has been collected.
Researchers say the use of clustering-based computation could remove the need for on-site inspections of panels by instead enabling real-time monitoring of degradation using only meteorological data.
Kaco is launching a mass-produced string inverter with silicon carbide switches onto the market following 10 years of discussion about the technology within the industry. In the 100 kilowatt plus segment, the technology produces small, lightweight devices with few components.
As problems with component failure have already laid bare, there is a clear need for contract clarity at every stage of a PV project, from material and component sourcing to power purchase and operations agreements. Here, pv magazine investigates a little covered issue for module buyers, which could threaten insurance coverage and the overall success of a project further down the line.
