The Colville Reservation in northern Washington. The Confederate Tribes of the Colville Reservation And Open Access Technology International (OATI) has announced a partnership to advance tribal energy sovereignty and resilience through the design and deployment of multiple solar and storage microgrids on the northern Washington reservation. The program represents an important step toward improving reliability, reducing outages and providing long-term energy independence for the Colville Tribes, which are governed by four legislative districts: Omak, Nespelem, Keller and Inchelium. The initiative is supported by federal and state grants and addresses vulnerabilities such as winter storm disruptions and wildfire risks. The Colville…

Researchers in China have developed an inverted perovskite solar cell that approaches the 27% efficiency threshold. The device contains a specially designed, self-assembled monolayer that passivates perovskite defects and improves efficiency. November 13, 2025 Emiliano Bellini A group of researchers led by China’s Lingnan University has fabricated an inverted perovskite solar cell via what they called a self-assembled monolayer (SAM) stabilization strategy. Inverted perovskite cells have a device structure known as “pin”, where hole-selective contact p is at the bottom of the intrinsic perovskite layer i with electron transport layer n at the top. Conventional halide perovskite cells have the…

In a major milestone for the two-year-old Series A startup and the wider stationary energy storage sector, US-based Peak Energy has signed a supply agreement potentially worth more than $500 million. November 13, 2025 Marija Maisch By ESS news Denver-based Peak Energy has announced a multi-year phased agreement with U.S. developer and operator of utility-scale battery storage Jupiter Power. Under the deal, Peak Energy will supply up to 4.75 GWh of its sodium-ion battery energy storage systems for deployment between 2027 and 2030. In the first phase, Peak will deliver approximately 720 MWh of storage capacity by 2027, marking the…

The Italian specialty module manufacturer has launched a new lightweight, semi-rigid, glass-free silicon solar panel reinforced with a thin aluminum sheet for marine, mobility and other off-grid applications. The series includes products with a power range from 145 W to 205 W. November 13, 2025 Valerie Thompson Italian specialty module manufacturer Enecom has launched a new semi-rigid, glass-free silicon solar panel reinforced with a thin aluminum sheet for marine, mobility and off-grid applications. The High Flex Strong line (HF Strong) has a power range from 145 W to 205 W with dimensions starting at 671 mm x 1,215 mm and…

Researchers from CSIR-National Physical Laboratory and IIT Madras have fabricated MoS2-coated GaN nanorods on tungsten foil to improve the photoelectrochemical efficiency of water splitting. Gallium nitride nanorods, prized for their electron mobility and stability, face limitations due to their large band gap that limits solar energy absorption. To address this, the team integrated molybdenum disulfide – a catalytic material – onto the nanorods. MoS2/GaN nanorods exhibited a photocurrent density of approximately 172 microamps per square centimeter, outperforming bare GaN nanorods by a factor of 2.5. This improvement was related to Type II band alignment, which improves charge separation, decreases charge…

The United Nations Development Program (UNDP) says emergency generators, some powered by solar panels, are being deployed as Cuba struggles to restore electricity after the storm. November 12, 2025 Luis Ini By pv magazine LatAm More than 1 million Cubans were without electricity for two weeks after Hurricane Melissa hit the eastern part of the island, damaging solar installations and flooding the 21.8 MW Río Cauto solar farm. The UNDP said it is installing generators in the communities of Guamo Viejo, Grito de Yara, Vado del Yeso and Cauto Embarcadero in Granma province. The Río Cauto facility is part of…

The solar cells combine multi-layer graphene with silicon wafers, harvesting both solar and kinetic energy for continuous use. Tests show that the cells can autonomously drive supercapacitors embedded in a temperature sensor. November 12, 2025 Emiliano Bellini Researchers from the University of Arkansas in the United States have fabricated a graphene-based solar cell that can be used in Internet of Things (IoT) applications. The device was developed as part of a research project intended to develop autonomous sensor systems that draw power from multiple sources in the environment, including solar, thermal, acoustic, kinetic, non-linear and ambient radiation. Graphene has been…

A Green Lantern solar project. Based in New York Send energy announced the acquisition of the community and commercial solar developer in Vermont Green Solar Lantern. Send energy, founded in 2024will acquire more than 64 solar and battery storage projects from GLS at various stages of development and operation, for a total of 208.9 MWdirect current. This acquisition expands Dispatch’s footprint in the growing distributed generation market in Georgia, Maryland, West Virginia, New York, New Hampshire, Vermont, Maine, Minnesota and Wisconsin. “Dispatch remains committed to the energy transition and we are pleased to welcome Green Lantern’s team, operations and assets…

Researchers in the Middle East have developed a fuzzy logic controller that simultaneously optimizes the tilt angle of PV systems and performs maximum power point tracking (MPPT). Years of simulations indicate that the proposed approach increases energy generation by approximately 20%. November 12, 2025 Lior Kahana A team of scientists from Prince Mohammad Bin Fahd University in Saudi Arabia explored the use of a fuzzy logic controller (FLC) to simultaneously optimize the tilt angle of photovoltaic panels and perform maximum power point tracking (MPPT). “The novelty of the current study is that it presents an intelligent optimization method based on…

The European Network of Transmission System Operators for Electricity (ENTSO-E) says new EU rules will make network-building functions mandatory for large-scale storage and renewable plants. November 12, 2025 Tristan Rayner and Pilar Sánchez Molina By ESS news ENTSO-E has published its report Phase II Technical Report on Networking Requirementsoutlining how generators, including inverter-based storage systems, will be mandated to stabilize the European electricity grid. The report is a hugely important amendment to the upcoming Network Code on Generator Requirements (NC RfG 2.0), which introduces binding grid-building obligations for new storage and renewable plants with a capacity of more than 1…
