Sun-tracking solar panels fold away from hail while lifting output nearly 40%

Researchers led by Armin Buchroithner from the Institute of Electrical Measurement and Sensor Systems at TU Graz have developed an innovative photovoltaic system that combines significantly higher output with protection from storms, hail and snow. The system, known as FLAPTrack (Face-to-Face Lay-Down Anti-Degradation Protection), continuously aligns the PV modules with the sun's position both horizontally and vertically.

For energy systems that power a reliable grid and avoid blackouts, the future is all about location

Will a warming climate and changing weather patterns lead to more grid blackouts and other energy disruptions? Answering that question requires studying both regional climate forecasts and local energy systems, including emerging renewable generation, storage, transmission lines and demand forecasts. The lack of such studies is one reason energy developers and grid operators rarely consider climate change when deciding where to build their next project.

Precision interface chemistry pushes perovskite solar cells beyond 26% efficiency

An international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n-i-p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.

E-learning helps regulators navigate a changing grid

It is the second day of a massive heat wave. Across the region, thermostats are cranked, air conditioners are laboring, and wind turbines have gone still. Without warning, a summer storm moves in, and the solar generation energy markets were counting on vanishes behind clouds. The heat saps the efficiency of conventional generators, too, and blackouts begin rolling through neighborhoods. People look up from their phones, annoyed and sweating, and wonder: Why isn't there enough power? Can't they just make more?

How digital participation can aid the energy transition

The active involvement of citizens, stakeholders and municipalities is essential for the success of the energy transition. Digital participation platforms promise broader access to planning processes. However, a new study, published in Renewable and Sustainable Energy Reviews, calls for a fundamental shift in how digital participation is implemented, arguing that it should be conceived as a comprehensive infrastructure supporting the entire planning process, rather than simply a collection of communication tools.

Safer lithium-ion batteries move closer as 3D-printed cobalt-free electrodes boost power

Since the early 2000s, lithium-ion (Li-ion) batteries have become the predominant rechargeable power source for many mobile devices, electric vehicles, renewable-energy storage grids and more. But the Li-ion batteries in commercial use carry both safety risks and limitations. Julia R. Greer, the Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering at Caltech, whose lab has been working to improve Li-ion batteries, has now established a new path toward making them less dangerous and more environmentally friendly while also boosting performance.

Researchers find 'trap' hindering performance of hybrid perovskites

A new study from Cornell researchers has revealed an unexpected obstacle to improving charge transport in hybrid perovskites, a promising class of semiconductor materials used in energy conversion and electronic devices. The research, published in Advanced Energy Materials, shows that certain conjugated organic molecules, long thought to enhance electrical conductivity in layered perovskites, can instead trap charge carriers and dramatically reduce conductivity. The findings could help guide the design of next-generation perovskite materials for applications ranging from thermoelectric energy conversion to optoelectronics.

3D photothermal design unlocks 8.5-fold higher solar evaporation for desalination and crop irrigation

The global shortage of freshwater has become a critical challenge. Conventional water treatment relies heavily on fossil fuels and associated infrastructure, which can make it unsuitable for remote and harsh regions. In contrast, solar thermal evaporation is a promising alternative, but its application is limited by material performance and production constraints.

Food waste can become jet fuel through simpler refining and 50-50 blending

The aviation industry accounts for a large portion of global greenhouse gas emissions. Biobased, sustainable aviation fuel (SAF) can mitigate climate impacts, but transitioning to SAF faces critical supply chain constraints. A research team at the University of Illinois Urbana-Champaign has developed a method to produce jet-grade fuel from food waste, contributing to a circular bioeconomy. In a paper published in Nature Sustainability, they focus on technical and economic considerations.

New battery management system makes electric car batteries safer and more durable

Just as an orchestra needs a conductor, a battery management system (BMS) controls the power storage of an electric vehicle. However, until now, monitoring has been based only on the voltages, currents and temperatures of the individual battery cells. Their aging or possible damage can only be checked externally using complex calculations.
