Scientists achieve 25.4% efficiency in perovskite solar cells with enhanced stability using multivalent ligands
Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85 C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.
Smart Commercial to roll out prefab vertical rooftop PV system
Smart Commercial Energy has unveiled a new prefabricated vertical rooftop solar system for the Australian market as part of a collaboration with Norwegian clean energy company Over Easy Solar.
EU Joint Research Centre proposes novel PV climatic classification
A research group from the European Commission Joint Research Centre has developed a new PV climatic classification, the first to address annual yield and performance ratio. Their work resulted in 10 globally applicable clusters. “It challenges the assumption that many more classes are needed to capture PV-relevant climate,” the researchers said.
UNSW researchers set new efficiency record of 11.02% for antimony chalcogenide solar cell
The Australian scientists designed the cell with a sodium sulfide additive to achieve uniform sulfur and selenium distribution, improving charge transport.
This controlled elemental layering reduces energy barriers and defects, enabling a certified efficiency of 10.7%.
Silver price hits all time high of $94.73 an ounce
Silver prices hit a record $94.73/oz on January 19. Silver analyst Philip Newman tells pv magazine the metal could soon surpass $100/oz, increasing pressure on PV module manufacturers to reduce silver usage.
China’s top regulators summon battery giants, warn against ‘below-cost’ price wars
Four agencies told 16 leading firms to rein in irrational competition as China tightens oversight of power and storage batteries.
Copeland releases sanitary water heat pumps
US-based Copeland has launched its Sensi Hydro sanitary water heat pump designed to provide energy-efficient hot water for hotels, commercial buildings, and public facilities. The units feature ZW scroll compressors, independent refrigerant circuits, and backup mode to ensure reliable hot water supply.
GCL, Cornex, TBEA to build solar manufacturing complex in Egypt
Egypt’s Kemet has signed three agreements with Chinese companies over the last week, covering plans for a 5 GW solar cell complex, a 5 GWh battery energy storage factory and Egypt’s first solar inverter factory.
European PV market faces potential 2026 price shock from China export tax
China’s PV manufacturing sector is operating at full capacity ahead of an April 1 export tax change, contributing to module price increases of 20% to 30% in parts of the supply chain and raising risks for price-sensitive European commercial and utility-scale projects in early 2026.
Poland draft grid law could slow solar and storage investment, warns industry
The Polish Photovoltaic and Energy Storage Association (PSFiME) says proposed changes to Poland’s energy law could impose high upfront costs on developers, raising market entry barriers and unfairly favouring large, well-capitalized players.
