E3/DC to replace 77 LG battery modules after fire in Germany
E3/DC says a residential battery integrated with an LG Energy Solution module recently caught fire in Werne, Germany, prompting the company to replace battery modules in 77 homes as a precaution. The cause of the blaze is still under investigation.
Solar cell based on silver bismuth sulfide exceeds 10% efficiency threshold for first time
This kind of solar cell technology had so far reached efficiencies of up to 9%. The new result was made possible by a post-deposition in situ passivation strategy to reduce surface defects in the device, according to its creators.
Dragonfly launches lithium iron phosphate battery for rooftop PV, off-grid applications
The US-based company said the new 12 V lithium iron phosphate product comes with a 10-year warranty and has a lifecycle of more than 5,000 cycles.

Utility-scale BESS: Best practices to mitigate hazards
A report from Leeward Renewable Energy has investigated battery energy storage system (BESS) fires and other thermal runaway events to try and put them into context.
Inverted perovskite solar cell based on co-absorbed self-assembled monolayer achieves 24.68% efficiency
A research team in China improved the efficiency and stability of an inverted perovskite cell using a co-adsorbed approach to incorporate self-assembled monolayers at the hole transport layer.
Scientists create PV-driven synaptic device for AI processing
A team from Tokyo University of Science has developed a solar cell-based computing device that mimics human synaptic behaviour to use in edge AI processing. The researchers say the device has the potential to accelerate the development of energy-efficient edge AI sensors in applications including health monitoring, surveillance and automotive technologies.
‘The crop people don’t understand the PV aspect’
University of Exeter academic Aritra Ghosh tells pv magazine a multidiscipline approach is required to unlock the full potential of agrivoltaics. Discussing a new paper comparing static and tracker agrivoltaics systems in the United Kingdom, the researcher argues better understanding of microclimates under modules and how PV affects crop biochemistry is needed.
Progress on standardized tests, protocols for vehicle-integrated photovoltaics
Researchers from University of Miyazaki in Japan have published a technical background paper about testing protocols to address the unique challenges of vehicle integrated photovoltaic (VIPV) modules. It features the background on a new numerical probability model that incorporates shading, partial-shading, dynamic shading, uneven terrain and modules’ curvatures.
