All solar cell efficiencies at a glance – updated
The Solar Cell Efficiency Tables, led by Professor Martin Green from UNSW, have been updated to Version 68 and will be available as open access in Joule starting from July 2026. The latest results show new efficiency records for large area silicon cells, modules, and lead halide perovskite cells. Progress has also been made with perovskite-silicon tandem cells and modules, indicating a positive trend towards more efficient and sustainable photovoltaic systems. Additionally, Version 67 presented a new record of 27.9% efficiency for an interdigitated-back-contact (IBC) device developed by Longi, showcasing significant advancements in solar cell technology since the tables were first published in 1993. Scientists from various institutions around the world, including the European Commission Joint Research Centre, Germany's Fraunhofer Institute for Solar Energy Systems, and the US National Renewable Energy Laboratory, have contributed to these advancements.

German consortium developing aluminum facade elements with integrated PV modules
Researchers from Germany have developed a PV-activated design facade element with aluminum as the base material, funded by Germany's Federal Ministry for Economic Affairs and Energy. The approach involves directly laminating a PV module onto the aluminum facade element, with challenges such as bending and electrical insulation addressed. The prototypes of the PV-activated facade element differ from a facade element without PV by only two connectors, making them more likely to be accepted and used by installers. Scientists have developed a prototype called BIPV-4 for a façade element that utilizes aluminum-based PV technology, demonstrating that it can match conventional module performance while maintaining safe electrical isolation. The design includes rear junction boxes, insulated cross-connectors, a zigzag 3D structure, golden anodized aluminum, and optimized use of M12 cells. The group also created multiple PV design façade variants with adaptable cell formats, different surface geometries, and customizable color options, allowing for integration into diverse façade geometries and scalable to different module sizes up to 2 meters.

German scientists explore whether solar power plants can induce rain in deserts
A research project led by the University of Hohenheim in Germany, funded by the UAE Research Program for Rain Enhancement Science, aims to assess the climatic impacts of large-scale photovoltaic installations in desert regions. The project will study how photovoltaic parks in coastal desert environments could potentially enhance rainfall by interacting with moisture-bearing sea breezes. The research will involve deploying high-resolution LiDAR systems and conducting measurements near large solar installations in the United Arab Emirates to determine optimal size, placement, and design parameters for maximizing their impact on precipitation formation. The project also explores integrating solar power generation with drought-resistant crops and water management strategies in arid regions. Disturbed atmospheric teleconnections could impact solar power generation in various regions including North Africa, Southern Europe, the Southern Arabian Peninsula, India, North Asia, and Eastern Australia.

How the Beneficial Design Institute is transforming Germany’s toughest textile waste
The Beneficial Design Institute in Berlin-Brandenburg, as part of the Circular Fibersheds sub-pillar of Earth's Solutions Framework, is piloting innovative ways to repurpose unrecyclable textiles into useful new materials for other industries. Germany's textile waste problem, with 1 million tons collected annually, is being addressed by focusing on blended, contaminated, and low-value materials that are difficult to recycle using traditional methods. The project aims to create biodegradable materials, such as beta-glucan, from textile waste, while also exploring the use of waste gases to grow microalgae for agricultural and industrial purposes. By building a system that treats even the hardest-to-recycle materials as valuable inputs, the project highlights the potential for reducing emissions, creating biodegradable materials, and supporting local economies through the reuse of textile waste. The next steps involve scaling up the process, improving coordination, and securing funding for a regional model of textile waste reuse.

New panel of climate scientists calls for fossil fuel transition roadmaps
A new panel of experts, including top climate scientists, is urging governments to develop science-based and just roadmaps for phasing out fossil fuels. The panel's recommendations were presented in Santa Marta, Colombia, ahead of a ministerial meeting on transitioning away from coal, oil, and gas. The panel emphasizes the need for whole-of-government plans to overcome barriers to the energy transition. A draft roadmap for Colombia, developed with input from European scientists, shows a pathway to economic and societal benefits through phasing out fossil fuels with energy efficiency measures and renewable energy. Developing countries need an exit route from the "debt trap" of fossil fuels to enable a just and effective transition. Brazil is working on a national roadmap for its economy and leading a global roadmap for climate solutions, with the new panel aiming to provide more specific and targeted advice at a faster pace than the IPCC. The transition beyond fossil fuels depends on cities and collective action, with recommendations including banning new fossil fuel infrastructure and implementing carbon levies on imports. The panel will be co-chaired by experts from Cameroon, Germany, and Brazil, and will consist of scientists working on transition pathways, technological solutions, policies, and finance.
