MGM Resorts achieves 100% daytime solar power on Las Vegas strip
Output from Estuary Power’s recently-completed Escape Solar and Storage project more than doubles MGM’s share of solar energy.
French scientists discover new UV-induced degradation pathways in heterojunction solar cells
Scientists from French research institute CEA-Liten have identified hydrogen migration in doped selective layers as the primary driver of UV-induced degradation in silicon heterojunction solar cells. They have also found that combined light and thermal light-soaking treatments can partially restore performance and improve long-term UV stability.
Australian startup moves forward with perovskite solar manufacturing plans
Halocell Energy is set to benefit from the development of a sovereign supply chain for high-purity precursors to perovskite after signing a memorandum of understanding with Queensland advanced materials company Lava Blue.
UK to spend $20 billion on home energy upgrades, mandatory PV for new homes
Cash grants and state-backed loans to support solar and battery storage installations in millions of UK homes as part of government Warm Homes Plan. UK government says investment has the potential to triple the number of homes with rooftop solar by 2030.
Italy installs 6.4 GW of PV in 2025
The country reached a cumulative installed PV capacity of 43.5 GW at the end of December, according to new figures released by Italian grid operator Terna.
Noon Energy demonstrates 100+ hour ultra-long-duration energy storage system
The pilot showcases a reversible solid oxide fuel cell battery and represents the first fully containerized, modular ultra-LDES system to be operated for thousands of hours, achieving more than 200 hours of energy storage capacity.
EGbatt releases 15 kWh storage solution for residential use
The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of over 9,500 cycles at a high 95% depth of discharge.
Scientists achieve 32.6% efficiency in perovskite-silicon tandem solar cell via interface engineering
Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.
Hungary adds 1.1 GW of solar in 2025
Hungary deployed over 1 GW of solar for the third consecutive year in 2025, driven largely by grid-scale solar additions. There are concerns momentum could slow in the coming years due to no new connection permits for large-scale projects authorized over the last three years.
Japan’s solar industry targets vertical bifacial PV with new guide
The Japan Photovoltaic Energy Association (JPEA) has released a voluntary reference guide to support adoption of vertical bifacial PV in Japan, outlining design, performance, and compliance considerations for projects in snow-prone, high-latitude, and space-constrained conditions.
