The US startup said the 30 x 30 cm perovskite solar cell device features tin oxide electron transport material produced in a sheet-to-sheet slot die coating process. October 15, 2025 Valerie Thompson Sofab Inks, a US-based manufacturer of functionalized metal oxide materials, has announced that its novel tin oxide (SnO2) electron transport layer (ETL) material has been used in a 22.2% efficient 30 x 30 cm mini perovskite solar module made with industrially compatible processes. The company’s Tinfab was applied as the ETL with a sheet-to-sheet slot die coating tool, according to Jack Manzella, COO of Sofab Inks, who noted…
On October 14, lawmakers, consumer activists and members of the renewable energy industry joined a broad coalition of organizations calling for immediate implementation of the Clean and Reliable Grid Affordability (CRGA) Act during Illinois’ fall veto session. This legislation responds to the urgent need to address the skyrocketing electricity costs for consumers and businesses. “Simply put, we need to pass the Clean and Reliable Grid Affordability Act, now. The cost of inaction is what Illinois taxpayers are paying, and every day we wait guarantees more pain for consumers and businesses in the future,” said Jeff Danielson, SVP of advocacy for…
North Carolina residents will see their electricity bills increase starting October 2025, as Duke Energy implements a rate adjustment across the state. This change comes at a time when many households are already grappling with rising costs of living, making the timing challenging for homeowners and businesses alike. The rate increase is part of Duke Energy’s plan to modernize North Carolina’s electrical infrastructure while transitioning toward cleaner energy sources. Understanding why these increases are happening can help you make informed decisions about your energy future and explore alternatives that might help offset rising electricity costs. The Foundation of Duke Energy’s…
EDP Renewable Energy Sources North America (EDPR NA) completed the 180 MW Azalea Springs Solar project in Angelina County, Texas. Azalea Springs Solar will produce enough electricity to power the equivalent of more than 27,800 average Texas homes annually Credit: EDP Renewables North America “Azalea Springs Solar demonstrates the powerful role that energy infrastructure can play in building stronger, more resilient communities,” said Sandhya Ganapathy, CEO of EDPR NA. “This project is an example of clean energy in action: strengthening Texas’ electric grid with reliable, domestic energy while stimulating economic growth in Angelina County and the entire region. We are…
Demand for copper, often considered one of the most valuable alternatives to silver in solar energy production, is expected to increase by almost a quarter globally by the middle of the next decade. Wood Mackenzie says the energy transition is one of four ‘disruptors’ that could cause demand to increase further. October 15, 2025 Patrick Jowett According to an analysis by the US research agency, global demand for copper will increase by 24% by 2035 Wooden Mackenzie. The consultancy firm’s latest report says global copper demand will increase by 8.2 million tonnes per annum (Mtpa) to 42.7 Mtpa by the…
When he was appointed Energy Minister, Ed Miliband promised that he would operate not on myths and false information, but on evidence.This was a pretty obvious one to reflect on a previous political term That allowed the penetration of largely untrue reports about the negative impact of solar energy development in parliament, which filtered through to the mainstream media and hit the industry where it hurt: public perception.Community buy-in for developers is an important factor in solar deployment, especially for utility-scale projects.Just over a year into the current government’s term, there has been a shift in the message from the…
Researchers in Canada have proposed using gravity-based energy storage in tall buildings, in combination with photovoltaic facades, small wind turbines and lithium-ion batteries. Their modeling indicated that this hybrid system could achieve a levelized energy cost ranging from $0.051/kWh to $0.111/kWh. October 15, 2025 Emiliano Bellini Researchers from the University of Waterloo in Canada have designed a solid gravity energy storage system that can be used to store renewable energy high-rise buildings urban buildings. The cable hoist-based system is designed to work in combination with photovoltaic facades installed on the south, east and west walls, as well as small wind…
Liquid metal templates increase the efficiency of printable perovskite solar cells A research team from Yunnan University has made a major advance in the field of printable mesoscopic perovskite solar cells (p-MPSCs) by introducing liquid gallium nanodroplets as heteroepitaxial templates to control crystal growth. The breakthrough, led by Professor Qingju Liu, enables significantly higher efficiency and stability than previously achievable with this low-cost solar technology. Printable mesoscopic perovskite solar cells offer great potential as a scalable and stable alternative to conventional solar photovoltaics. However, their energy conversion efficiency has long lagged behind planar perovskite cells due to limited crystal growth…
Cameroon and Zambia are implementing government programs that bring solar mini-grids to communities without stable access to electricity. Cameroon recently deployed two solar power plants to power two villages, while Zambia deployed four solar mini-grids in the country’s Central Province. October 14, 2025 Patrick Jowett Cameroon and Zambia are among African countries that have recently deployed solar mini-grids in rural communities. Cameroon’s Ministry of Water and Energy last week inaugurated two solar power plants in the villages of Songmambias and Nkelassi in Mefou-et-Akono, a department in the country’s Central Province. The two installations each cover more than 900 m2, are…
The U.S. Department of the Interior Bureau of Land Management (BLM) has canceled an environmental impact assessment of Esmeralda 7, a proposed 6.2 GW solar and storage project in Esmeralda County, Nevada. The seven separate arrays that would compose Esmeralda 7 were located on 62,300 acres of BLM land. The Gemini Solar + Storage project in Nevada. Primergy The project is listed as canceled under the National Environmental Policy Act status BLM website. World of solar energy contacted the BLM for comment but received a voicemail saying no one is in office due to the federal government shutdown. Esmeralda 7…
