A global research team has developed a tandem solar cell with 30% transparency by combining perovskiet and organic layers, achieving a record of 12.3% efficiency for transparent solar cells. March 21, 2025 Patrick Jowett An international research team has achieved record efficiency for transparent solar cells. Researchers of the EU-funded CitySolar project, including nine partners from seven countries, developed a solar cell that generates electricity while light can continue. The device integrates perovskiet and organic solar cells, so that it can capture different parts of the light spectrum. “The tandem solar cell mainly harvests energy from the infrared and ultraviolet…
Researchers in Portugal have simulated 800 wealth purchase Agreements on eight different contract type and have found that contracts with a variable price structure achieve higher performance. Their analysis considered net contract value, contract performance deviation and Volumerest as the most important indicators. March 21, 2025 Emiliano Bellini A team of scientists in Portugal has assessed the performance of various structures of the Corporate Power Purchase Agreement (CPPA) and has found that contracts based on a variable price structure reach higher performance, while they offer the lowest performance based on profiles with a fixed attitude. The researchers emphasized that, despite…
Local authorities and community energy groups are supported by around £ 12 million to build clean energy projects. Image: Ed Miliband via X. Energie -Secretary Ed Miliband has announced the first project that Great British Energy, a public of public ownership, will undertake. An investment of £ 200 million from the British government and GB Energy will collaborate with schools and the NHS to install Solar PV on the roof at a total of 400 locations, which provide between 70 MW and 100 MW of solar generation. In England, about £ 80 million in financing will support around 200 schools,…
Mission Solar Energy, one of the longest running manufacturers of solar panels in the United States, will soon also make solar cells after its parent company OCI Holdings has announced new production plans. OCI Terrasus Polysilicon processing OCI will invest $ 265 million in the site, which should start with commercial production in 2026. The factory will have an annual capacity of 1 GW with space to grow up to 2 GW. OCI will deliver the polysilicon from his subsidiary of Malaysia OCI Terrasus. No official details have been released at the wafers manufacturer. “The establishment of this new subsidiary…
A research team of two London universities has developed a multi-layered device that tackles the instability of organic materials in water to promote their use in direct solar hydrogen generation. Monolithic Tandemanodes made by the team achieved a solar-to-hydrogen efficiency of 5%, a record in organic photo-electrocrochemical device performance. March 21, 2025 Patrick Jowett A team of researchers from Imperial College London and Queen Mary University of London have developed a method to utilize solar energy for hydrogen production. In the research paper “Improved oxidation of solar water and non-supported water split with the help of graphite secure bulk hetero…
A research group including scientists from the American National Institute of Standards and Technology (NIST), Underwriter’s Laboratories Inc. And the National Renewable Energy Laboratory (NREL) has outlined a new protocol for assessing PV module Achterbraak breakdown in the field. Through the proposed framework, the researchers analyzed PV -rear breakdown at 41 locations, with exposure times ranging from 1 to 38 years. March 21, 2025 Emiliano Bellini A group of researchers led by the Western Reserve University Case in the United States has developed a field research protocol for the monitoring of PV -module rider shoes. “We have performed the protocol…
US President Donald Trump has withdrawn the designation of the Defense Production Act (DPA) for solar production and other clean energy technologies, which means that a Biden era is reversed to stimulate domestic production. March 21, 2025 Ryan Kennedy By PV Magazine USA US President Donald Trump has issued an executive order that a series of actions can be canceled by the Biden administration. The order included the removal of solar modules, solar modules components, insulation, electrolyzes, fuel cells and electric heat pumps from Section 303 of the Defense Production Act (DPA). In 2022, Biden called on the DPA To…
Nanocellulose infused with red onion extract protects solar cells from UV breakdown Researchers from the University of Turku in Finland have developed a BIO-based film that offers a powerful UV protection for solar cells, treated with red ui-skin extract with the help of nanocellulose. This marks the first comparative study of how different bio-derived UV filters perform over time. Solar cells, susceptible to damage caused by ultraviolet radiation, are typically protected by films derived from petroleum such as polyvinyl fluoride (PVF) or polyethylene -terefhtalate (PET). In an attempt to reduce the dependence on fossil fuels, researchers investigate sustainable alternatives such…
Assessment of the difference in costs, functionality and activities of fuel generators versus home batteries. March 20, 2025 Ryan Kennedy By PV Magazine USA The risk of grid blackouts is increasing and the Ministry of Energy said that weather-related power outages again increased by 80% in the United States from 2011 to 2023. With the American grid aging or need for repair, homeowners turn to a backup power at home. There are two main options for back -up power: traditional gas generators and storage systems for battery energy. How do they compare? Gas generators usually run on diesel, propane or…
Scientists have created a new probabilistic model for 5 minutes ahead PV Power forecasting. The method combines a conventional neural network with bidirectional long -term memory, attention mechanism and natural gradient boost. March 20, 2025 Lior Kahana A research group led by scientists from Hong Kong Polytechnic University has presented a new probabilistic ultra-red-red period PV-current prediction method based on a conventional neural network (CNN) and a bidirectional long-term memory (Bilstm) with a attention mechanism. The new technology gets patterns from historical weather data and then predicts the output with natural gradient boosting (NGBOOST). “Quantifying the uncertainty of prediction is…
