U.S. authorities warn of hidden radios in PV-powered highway infrastructure
The U.S. Federal Highway Administration (FHA) has warned that cellular radios have been found in unspecified foreign-made inverters and batteries used in PV highway infrastructure, according to Reuters. pv magazine speaks with cybersecurity expert Uri Sadot about the risks.
RE+: Ten cutting-edge technologies from North America’s largest solar trade show
New solar panels, battery energy storage systems, factory announcements and more are set to be unveiled at RE+ Las Vegas, Nevada, Sep 8-11.
All back-contact perovskite solar cell designs at a glance
Scientists from Japan, Saudi Arabia and the United States have investigated existing back-contact perovskite solar cell architectures and have proposed a strategy to help reach commercial production.
New hail test aims to more accurately measure solar panel resilience
A new test curve for determining solar panels’ breaking point from hail uses a broader spectrum of impact energies and testing products.
Finetuning 2D Dion-Jacobson perovskites for photovoltaic applications
Canadian and U.S. researchers have investigated applying pressure to a 2D hybrid organic-inorganic perovskite to tune the optical and electronic properties to suit photovoltaic applications, light emitting diodes or other semiconductor devices.
New deep learning tech for PV inverter fault diagnosis
A team of scientists at Georgia Southern University has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
Clean energy transition requires more comprehensive local planning, study says
Local energy initiatives have increased at the local level, but researchers say more focus on addressing spatial planning and economic benefits is needed in the renewable energy transition.
Solar leads as U.S. grid interconnection agreements grow 33%
Interconnection agreements grew 33% year-over-year in 2024 and are sustaining momentum through 2025, said Wood Mackenzie.
Inside perovskite solar cell durability and performance testing
Accurately measuring the performance of perovskite solar cells and modules requires significant modifications to long-established testing standards used in silicon PV. Researchers are settling on methods that rely on up to several minutes of constant light exposure and other time-consuming procedures. These may be fine for the laboratory setting, but those looking to produce this technology at scale need standardized methods that can characterize cells and modules at a much faster rate.
Dynamic pricing is superior to virtual power plants, says dynamic pricing pioneer
As California pursues dynamic pricing of electricity to help integrate renewable generation, industry pioneer Edward Cazalet says dynamic pricing can meet California’s demand flexibility needs better than virtual power plants can.
