Atess Power releases 100 kW/150 kW commercial inverters
Atess Power says it has developed 100 kW/150 kW commercial inverters with two maximum power point trackers (MPPTs), a 600 V to 900 V battery voltage range, and 10 milliseconds on/off grid transfer capability.
Enteligent secures $6 million to scale solar EV charging tech
US startup Enteligent says it has obtained $6 million to scale up its electric-vehicle (EV) charging technology, which enables direct DC-to-DC charging from solar panels without converting to AC.
Chinese scientists achieve record-breaking 20% efficiency in single-junction organic solar cell
Researchers from the Wuhan University of Technology in China have designed and synthesized a new non-fullerene acceptor for organic solar cells. One of their fabricated devices achieved the highest certified efficiency ever reported for single-junction organic solar cells.
Northvolt closes Cuberg’s ops, shifts lithium-metal battery R&D to Sweden
Three years after acquiring US-based Cuberg, Swedish battery maker Northvolt has decided to shut down the California unit and move future lithium-metal battery R&D to Sweden.
New direct lightning protection design for east-west rooftop PV systems
Scientists in the Emirates have developed a novel lightning mast layout that reportedly eliminates shading effect on PV panels. The proposed approach also addresses earth grid requirements under varying moisture conditions.
Direct vs. indirect coupling in PV-driven hydrogen generation
Researchers in Spain have made a comparative analysis of annual PV-powered hydrogen production for direct and indirect configurations and have found that indirect systems not only produce more hydrogen but also that they show higher resilience to module power losses.
Sineng Electric turns on 150 MW/300 MWh of storage in China
Sineng Electric has switched on a 150 MW/300 MWh standalone energy storage station in Guangxi, China, featuring battery energy storage system (BESS) containers, a central power conversion system (PCS), and a booster station.
Novel bifacial flexible PV cell offers 27% efficiency
Scientists have simulated dozens of electron transport layer-free cell structures and have identified the optimal design with a Zr:In2O3 front transparent electrode, a CuSCN hole transport layer, and a NAN rear transparent electrode. They have also optimized its thickness and bandgap.
Getting lightweight, flexible, semi-transparent PV from lab to fab
German research group Helmholtz Association hopes to speed up the adoption of flexible printed solar PV technologies by transferring advances in the lab to industry through its growing Solar TAP initiative.
Researchers use artificial neural networks to optimize PV tilt angles
Scientists have tested several machine-learning algorithms to predict the optimal tilt angle (OTA) of solar projects in 37 Indian cities, leading to improvements of up to 90%.
