  • Blue State Steps Up To Save Farmers With Solar Power

    New Jersey has launched a Dual-Use Pilot program to demonstrate the benefits of agrivoltaics, combining solar power and farming to maximize land use efficiency and provide new revenue streams for farmers. Rutgers University is leading the initiative, aiming to install 200 megawatts of solar power on farmland. Despite challenges like navigating state incentives and land conservation regulations, the program could lead to more farms adopting solar power in New Jersey. The state's innovative approach to solar development, including rooftop capacity and emerging trends like gas station and balcony solar, is helping progress towards renewable energy goals. Dual-use solar power offers a promising solution to support farmers and generate additional revenue while addressing the shrinking farm size in New Jersey.

  • The impact of electron irradiation on PERC, TOPCon solar cell performance

    UNSW researchers have found that electron irradiation significantly degrades the bulk minority carrier lifetime of silicon solar cells, leading to up to a 60% drop in efficiency. The study identified vacancy-vacancy defects as the main radiation-induced defects affecting the cells. They emphasized the need to increase radiation tolerance in commercial space silicon solar cells, with p-PERC cells showing superior radiation tolerance compared to p-TOPCon cells. Front-junction architectures were found to perform better than rear-junction designs in terms of radiation damage. The findings were presented in the study "Electron radiation-induced degradation of silicon solar cells" published in Solar Energy Materials and Solar Cells, highlighting various degradation mechanisms and vulnerabilities in TOPCon solar cells.

  • Solar sidewalks in Canada cut urban emissions 98%, claim scientists

    Research from Concordia University in Montreal suggests that integrating solar panels into sidewalks could be an effective way to create a green city. The study proposes using sidewalk-embedded photovoltaic panels to power local electric vehicle-based delivery networks and food logistics, while traditional solar sites are used for community gardens. The 15-minute city model aims to bring daily needs closer to residents to reduce fossil-fuel-consuming trips. The research, focusing on the impacts of sidewalk PV panels, found that a small area of panels could power the entire urban mobility system and significantly reduce emissions. The model also incorporates vegetable crops into the urban landscape, creating a self-sufficient cluster for certain vegetables.

  • Efficient solar PV cooking with sand-based thermal energy storage

    Scientists in Ghana have developed a solar PV-powered steam cooker with sand-based thermal energy storage, achieving a thermal efficiency of 38.9% and a payback period of 4.5 years. The system utilizes sand for its thermal stability and low cost, with the potential to reduce emissions and support Ghana's climate targets. Testing showed the system could cook large quantities of food efficiently and reliably, with a lifecycle cost analysis indicating significant cost savings compared to traditional biomass stoves. The integration of steam cooking with sand-based TES in solar PV-electric systems is a novel approach with promising results for sustainable cooking solutions. The Nkrumah University of Science and Technology, Technology Consultancy Centre, International Centre for Innovation, Manufacturing, Technology Transfer, and Entrepreneurship, and Cape Coast Technical University are likely involved in technology and innovation related to climate solutions.

  • Solar microgrid brings energy security to White Earth Nation

    The White Earth Nation's Pine Point community in Minnesota is advancing a community-owned resilience project with a 500-kilowatt solar array and battery storage to provide energy security and emergency backup power. Despite facing obstacles, including frozen federal grant programs, the project received funding from the U.S. Department of Energy's ES4SE Program and the Minnesota Solar for Schools program. Led by climate justice developer 10Power, the project aims to provide clean, reliable power while also incorporating an Ojibwe-language educational program and job fair. The Pine Point Resilience Hub is expected to come online in early 2026, serving as a model for community-owned energy in northern Minnesota and connecting energy technology with cultural identity and language revitalization.
