Moisture-resistant perovskite solar cell with 25.14% efficiency
An international research team has fabricated a perovskite solar cell using sulfur-based additives to improve its resistance to moisture. The device not only achieved high efficiency levels but was also able to retain about 96% of its efficiency after 1,000 h.
The Hydrogen Stream: new model and repository for accurate pre-feasibility studies
European researchers have told pv magazine that hydrogen production costs are often underestimated in prefeasibility studies, while the South Korean authorities have reported a rise in deals for large-scale hydrogen consumption projects.
Overhead agrivoltaics could disrupt global navigation satellite systems used for precision agriculture
Fraunhofer ISE researchers have investigated whether PV panels installed above orchards can affect the reception of global navigation satellite system (GNSS) signals and, in turn, affect the precision of advanced autonomous tools. They found a disruption and suggested some alternatives.
Onyx Solar launches walkable PV tiles
The Spanish building integrated PV manufacturer has launched glass-glass modules suitable for rooftops and other urban spaces. The new products have a nominal capacity of 75 W.
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.
The Hydrogen Stream: UK scientists call for strict rules for H2 leakage
The Oxford Institute for Energy Studies says addressing hydrogen leakage across the supply chain is crucial to making hydrogen a sustainable energy vector. Italy, meanwhile, has unveiled its national hydrogen strategy, with a focus on its role in the Mediterranean.
Barcelona testing PV shade canopies
The Barcelona City Council is piloting two solar system prototypes designed to provide shade, generate power, and filter air.
Colombian researchers design agrivoltaic system with hydroponic towers
Colombian researchers have designed an agrivoltaic system integrating hydroponic growing towers. The modular array, consisting of stackable 20 cm rings, creates a structure up to 2.5 meters tall, optimized for cultivating approximately 80 plants per square meter.
The Hydrogen Stream: EU offers financial support for renewable H2 auction
The European Commission, Austria, Lithuania, and Spain have announced new financial support measures for renewable hydrogen development as the European Union prepares for the second European Hydrogen Bank auction.
The Hydrogen Stream: Mibgas, DH2 Energy launch Iberian H2 auction
Portuguese researchers say that raw materials are not a major concern for the European supply chain, while Mibgas Derivatives and DH2 Energy have launched the Iberian Peninsula’s first renewable hydrogen auction.
