Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences have reported a new interface engineering strategy that significantly increases the efficiency and stability of three-dimensional perovskite solar cells. Working with international partners, the team formed a thin two-dimensional perovskite phase at the buried interface of the perovskite absorber, a location that has been difficult to selectively target with previous approaches. The work, published in Nature Energy on February 6, shows that the method improves the crystallization quality of the perovskite films and reduces defect concentrations at buried interfaces by more than 90…

French solar manufacturer Heliup has raised €16 million to scale up production of lightweight solar panels designed for commercial and industrial roofs with low load-bearing capacity. March 5, 2026 Gwénaëlle Deboutte By pv magazine France Heliup, a French industrial deep-tech company, has raised €16 million to accelerate the large-scale deployment of its lightweight PV technology. The company produces lightweight solar panels designed for existing roofs with low load-bearing capacity and wants to tap into a large, still underutilized market. The financing round was led by Supernova Invest, with participation from new investors MAIF Impact, Lita Gestion and C2AD. Existing investors…

EirGrid has warned of a “potentially challenging situation” for the country’s electricity system between 2026 and 2028, as rising demand threatens to exceed available generation capacity. In its latest All-Island Resource Adequacy Assessment, the operator analyzed the balance between electricity supply and demand in Ireland over the next ten years. The report shows that between 2026 and 2028, both basic and secure assessments will fall outside Ireland’s three-hour reliability standard, indicating that additional capacity will be needed to maintain the adequacy of the system. Conditions improve towards the end of the decade. From 2029, the basic assessment will return within…

The 1 MW test facility is located in Xuwei New Area, Lianyungang, Jiangsu Province. It is designed to generate long-term field data on large-area perovskite modules in coastal conditions. March 5, 2026 Vincent Shaw A 1 MWp perovskite PV field test plant in Xuwei New Area, Lianyungang, Jiangsu Province, China, was connected to the grid and became fully operational in late February 2026. The project, formally named the Xuwei New Area Novel Perovskite Distributed PV Demonstration Power Station, was developed and owned by Jiangsu Fangyang New Energy Investment Co., Ltd.the investment platform for sustainable energy Fangyang Group. The facility is…

The number of UK schools installing rooftop solar with funding from Great British Energy (GBE) has reached 100.The government energy company focuses on schools and colleges in deprived areas, particularly in the North East, West Midlands and the North West. Every region of England now has at least ten schools benefiting from the scheme.This is a major expansion of the scheme, with only 23 installations completed by November 2025. Company CEO Dan McGrail said: “Reaching 100 schools is a key milestone in our mission to reduce energy bills and means more money can be spent on education.”GBE will continue to…

Arevon Energy, a renewable energy developer, commenced operations at the 430 MWDC Kelso Solar Project in Scott County, Missouri. Arevon Energy broke ground on the 430 MWDC Kelso Solar Project in May 2025. Arevon developed, built and will own and operate the Kelso Solar Project. The two-phase installation, Arevon’s first large-scale project in Missouri, increased the state’s solar capacity by nearly 50% and generates enough energy to power more than 62,000 homes annually. During construction, the project employed more than 450 staff and is estimated to pay out more than $62 million in property taxes over its life, supporting schools,…

Estimates indicate that Japan added between 5.8 GW and 6 GW of solar power last year, likely pushing the country past 100 GW of cumulative solar capacity. Last year’s installations were led by the commercial and industrial markets, while the residential sector also saw increased demand. March 5, 2026 Patrick Jowett Japan added between 5.8 and 6 GW of solar energy last year, according to estimates from Tokyo-based solar consultancy RTS Corp. The estimate indicates that Japan’s cumulative solar capacity could now easily exceed the 100 GW threshold. According to data available on the International Energy Agency Photovoltaic Power Systems…

The Industrial Accelerator Act says that solar projects awarded through government procurement or other public support schemes must include European-made solar inverters and cells within three years of the law coming into force. For battery energy storage systems, similar requirements would be introduced in a phased approach starting one year after the law comes into force. March 5, 2026 Patrick Jowett The European Commission has adopted a legislative proposal aimed at introducing EU-defined content requirements for products that receive public funds. including solar photovoltaics and battery energy storage systems (BESS). The draft regulation, known as the Industrial Accelerator Act, proposes…

The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving 4.52% efficiency and improved stability. March 5, 2026 Ev Foley Researchers from the University of Seoul (UOS) and Joenbuk National University (JNU) in South Korea have developed a novel double-layer tin oxide (SnO2) electron transport layer (ETL) via a simple spin-coating method, which significantly improves the efficiency and stability of back-contact perovskite solar cells (BC-PSCs). “We chose SnO2 for the ETL because of its favorable conduction band alignment with perovskite and superior electron mobility compared to conventional titanium…

Solar engineer and ABC Solar founder Brad Bartz will deliver a keynote-style lecture titled “The Palos Verdes Landslide: Who Turned the Power Back On?” during an upcoming community event at AltaSea at the Port of Los Angeles on March 14, 2026. The presentation combines scientific storytelling with real-world engineering experience, exploring how fundamental physics principles translate into resilient energy solutions. Bartz, who founded ABC Solar more than 25 years ago, is known for emphasizing the practical use of solar and battery technologies under challenging conditions. His upcoming lecture starts with a surprising starting point: quantum mechanics. “Solar energy starts with…
