Lithuanian researchers promote solar cell technology Researchers from Kaunas University of Technology (KTU), Lithuania, who previously developed high-efficiency solar cells, have expanded their invention. The self-assembling monolayers can now be applied in perovskite solar cells with both inverted and regular structures. Self-assembling molecules form a layer one molecule thick and act as an electron transport layer in solar cells. “The molecules that make up these monolayers, like a smart glue, cover the surface of the constructed devices with a thin layer one molecule thick. And this is not random, they do not stick wherever they go, but attach themselves by…

Visionpark said its new solution for solar carports is self-weight and does not require a foundation. It can reportedly house all kinds of solar panels and be installed quickly. May 24, 2024 François PuthodBy pv magazine FranceThe French startup Visionpark has developed a solar carport solution based on concrete.“The concrete structure we use is self-weighting and does not require a foundation,” says the company’s founder, Armand Téolis. pv magazine France. “Above all, it is very quick to install. For example, a 500 kW installation can be completed in fifteen days. There is therefore no need to anchor the structure and…

Today, the Solar and Storage Industries Institute (SI2) released model policy that encourages the adoption of automated rooftop solar permitting software. This release comes like the American hits 5 million solar installationsof which more than 97% are on residential roofs, and this total looks set to double over the next six years. The model policy provides states with a template to encourage local governments to adopt automated rooftop solar permitting software. The software helps governments, homeowners and solar companies reduce the costs of rooftop solar permits and inspections by standardizing, streamlining and automating the permitting process. “As states struggle to…

Work on the new BESS is expected to start this year. Image: Zenobe Atlantic Green has signed a deal worth almost £200m with Ameresco, which will build a new 300MW battery energy storage system (BESS) alongside Envision Energy. The Cellarhead BESS project will connect to National Grid’s Cellarhead substation in the West Midlands and will have a maximum energy capacity of 624 MWh. Construction is expected to start this year and the final connection to the electricity grid is planned for the end of 2026. The development agreement between the parties is worth £196.5 million; The long-term agreement stipulates that…

An international research group has used a newly designed coalition game system to ensure economic justice among energy community members. The game system takes into account different types of prosumers who rely on standalone and combinations of solar energy and storage. May 24, 2024 Lior KahanaAn international group of scientists led by China’s Sichuan Normal University has developed a novel coalition gaming system that maximizes the collective payoff of prosumers in a community-level peer-to-peer (P2P) energy trading market.A coalition game is part of game theory, in which players form coalitions to achieve common goals and higher benefits.“The methods presented in…

Climate policy is a contentious issue in parliament, especially in view of the upcoming elections. Moving the date means decisions will have to be speeded up or abolished altogether. Image: Rishi Sunak via Twitter. On May 22, British Prime Minister Rishi Sunak announced that the next general election will take place on July 4 this year. The announcement, long before the major political parties began meaningful campaigning, came as a surprise to most political commentators. Sunak said: “I have never and will never let the people of this country face the darkest of days alone,” and acknowledged that “Putin’s invasion…

Waaree Energies says it will supply 445 MW of its 540/545Wp double-glazed PV modules to Statkraft India’s solar projects in Rajasthan, India. May 24, 2024 Uma Gupta By pv magazine USAWaaree Energies, India’s largest solar panel manufacturer, said this week it has won a contract to supply 445 MW of its bifacial modules to Statkraft India’s single-site PV projects in Bikaner, Rajasthan.It will supply its 540/545Wp double-glazed bifacial modules. Delivery of the modules is scheduled between May and August 2024.“This partnership with Statkraft India represents a critical step in our collective mission to contribute to the transformation of renewable energy…

About 60% of California energy customers have integrated battery energy storage into their rooftop solar installations. However, a “continued downturn” is expected for the market. May 24, 2024 Ryan KennedyBy pv magazine USACalifornia transitioned its rooftop solar policy on April 15, 2023, eliminating net energy metering (NEM) and moving to a net billing rate structure (NBT). This change reduced the rate paid to customers for exporting their excess solar production to the grid by approximately 80%. A year later, Lawerence Berkeley National Laboratory (LNBL) has a report evaluating changes in the state’s rooftop solar market. LNBL found that rooftop solar…

Scientists in China built a four-terminal tandem perovskite cell for the first time, with a 17.88% efficient perovskite device on the top and a 7.85% efficient lower antimony selenide cell on the bottom. The main features of the tandem cell are the transparent conductive electrode used to enhance the spectral response of the top cell and the “double” electron transport layer of the antimony selenide cell. May 24, 2024 Emiliano BelliniA group of researchers from the University of Science and Technology of China have fabricated a four-terminal (4T) tandem solar cell based on an upper cell that relies on a…

The BechtelThe constructed Cutlass Solar 2 project in Fort Bend, Texas, has been completed and is generating electricity at full capacity for the first time. The 218 MW solar installation delivered for Sabanci climate technologies includes almost half a million solar panels spread over 1,100 hectares.The project now sends enough clean renewable energy to the grid to power 40,000 homes – a milestone ahead of the 13-month delivery schedule. Cutlass Solar 2 is the second solar facility in Texas built by Bechtel, which completed the neighboring Cutlass Solar 1 plant in January 2023. In total, Cutlass Solar 1 and Cutlass…
