Perovskiet solar cell performance shows seasonal variation in long -term field test In a multi-year outdoor research, researchers from Helmholtz-Zentrum Berlin (HZB) have discovered significant seasonal fluctuations in Perovskiet solar cells. Led on the roof of the Adlershof campus, the long-term experiment exposed different solar technologies to natural weather conditions, in particular aimed at perovskiet cells that are known for their high laboratory efficiency and low production costs. Dr. Carolin Ulbrich and Dr. Mark Khenkin have analyzed operational data for four years, which shows that perovskiet solar cells retain excellent efficiency in the summer, but experience remarkable falls in the…

In this contributed article, Mark Macaulay, partner, Adam Brown, counsel, and Roddy Cormack, senior employee, of the project team of law firm Dentons focuses on the market opportunities for pump supply hydropower.Inertia, an important but complex physical aspect of electricity systems, is the ability to rotate machines, traditionally through thermally driven turbines, to offer system stability by resisting sudden frequency changes.System frequency stability refers to maintaining the work frequency after disruptions between generation and load – such as peaks in the electricity demand or malfunctions. This is crucial for power delivery and preventing damage to equipment. Rasters that are fed…

In search of the ‘holy grail’ of decrease agreements as the use of solar energy and negative prices grow”The trend is clear: the sensitivity of projects for negative prices will rise,” says Stirling Habbitts, director of business development and director of hydrogen at Source Galileo, who moderate a discussion about the growing challenge of negative energy prices in European power. France, for example, registered zero or negative prices For the entire May.Habbitts added that this could become more of a challenge for the United Kingdom, taking into account recent changes to the Contracts For Difference (CFD) scheme.“Earlier, the CFD schedule…

Global investment firm KKR has promised Aud 500 million ($ 328.2 million) to work with Australian Renewables Company Cleanpeak Energy and support the growth of the distributed energy platform, aimed at solar energy, battery energy storage and Microgrid’s solution. July 28, 2025 David Carroll By PV Magazine Australia US headquarters KKR has announced that the Aud will invest 500 million to support Cleanpeak Energy in growing and developing a pipeline of solar and front-with-meter solar, battery energy storage systems and microgrids for the commercial and industrial (C&I) sector of Australia. Cleanpeak was founded in 2017 and has established itself as…

New analysis of the adjustment of solar energy plants with energy storage, good for the rapidly falling prices of the industry, suggests that preparing your solar projects today has a strong chance of being in your financial interest. July 28, 2025 John Fitzgerald Weaver By PV Magazine USA Multiple clean energy Megatrends are converging: exponential growth in implemented solar energy and storage capacityTogether with a fast decrease storage prices That makes batteries cost -competitive. These shifts transform what is possible for developers, utilities and grid operators, not only in the scaling of renewable energy, but also in how and when…

Researchers in Taiwan have developed an adjustable aluminum reflector system that increases the performance of vertically mounted bifacial solar modules. The prototype yielded a total power gain of 71.32% on a baseline system without reflectors. July 28, 2025 Emiliano Bellini Researchers from the National Taiwan University of Science and Technology have developed new adjustable reflection systems to increase the performance of vertical bifacial PV arrays. “The system is able to automatically change both the tilt angle and the effective length on an hourly basis, based on real-time data from solar height and wind speed,” explained the scientists and noted that…

The removal of the onshore wind ban has been a blessing for the British wind sector, but industry experts warned that the obstacles still have to be overcome before a full wind wind ‘Renaissance’ is delivered.This was the most important conclusion that was drawn from a panel discussion that was held in the wind sector of the British onion sector during the wind energy and investment summit of this morning, organized by Zonne Media in London. The discussion, held under the heading ‘The Renaissance of British onshore wind: capitalizing on the U-Turn policy’, came as the British approaches A year…

Great British Energy will find opportunities to develop technological sovereignty in the supply chain to encourage the concept of energy that it has been designed in the UK that supports the recently released industrial strategy.That is what Rob Gilbert, director Supply Chain at GB Energy, told PV Tech Managing Editor Ben Willis to a discussion at the UK Solar Summit in London in London, yesterday (July 1).Introduction to him, Willis said that we “see the organization take on a clear form”, and notes that one of the objectives of the state -owned company is to create local jobs and to…

EatonIn his dedication to achieve net-zero operations by 2050, a 4-MW solar system will install at one of the activities in Wisconsin. Working with WEC Energy Group -subsidiary company We energies, Eaton will be the project next to Thomas A. Edison Technical Center In Franksville, Wisconsin and the Array, 30% of the annual carbon reduction goals are expected to achieve five Eaton locations in the state. Combined with earlier upgrades for energy efficiency, since 2018 the initiative will support a 58% reduction in the emission of Eaton’s greenhouse gases throughout the state. “At Eaton we tackle the energy transition from…

“We have been paying the price for our exposure to gas for far too long, and we have to do what we can do to remove that volatility, and this sprint at our own power is part of that,” said Michael Shanks MP, parliamentary under-secretary of State, State for Energy, who has organized the Solar Media, organized by Solar Media.Many of Sank’s comments were aimed at the financial robustness of the British solar industry. Since solar energy is one of the leaders in falling level figures of electricity (LCOE) in the room for renewable energy, there is a growing interest…
