Solestial designing space solar array with shorter lead time
The U.S.-based manufacturer of silicon solar PV technologies for space announced a project that requires it to manufacture, assemble and integrate 1 kW of solar cells and modules into a novel solar wing within a four-week time-period.
Compressed air energy storage enhanced by gravity
Scientists in China have simulated an advanced adiabatic compressed air energy storage, to which they added an elastic airbag with a heavy load situated above it. The energy, exergy, and economic analysis of the system showed that, due to the constant weight of the heavy load, the airbag’s pressure level remains unaltered during operation.
Features driving efficiency complicate solar cell disassembly, recycling
Researchers in Germany have sought to identify the features that may define the “ideal recyclable solar cell” and have found that the recyclability of PV devices is usually in contrast with the efforts of reaching high efficiencies.
GoodWe launches scalable C&I battery system with over 100 kWh capacity
GoodWe has released its BAT series battery cabinet for small to mid-scale commercial projects, with two capacities at launch at 102.4 kWh and 112.6 kWh, and outdoor use in mind.
Photovoltaic inventions increased seventeen-fold in three decades
The European Patent Office says China has overtaken other countries in photovoltaic patent filings over the past 15 years, while European startups and universities retain a lead in agrivoltaics and niche solar applications.
Philippines’ rooftop solar capacity estimated at over 1.8 GW
A new solar mapping tool in the Philippines shows that the country’s rooftop solar capacity exceeds 1.8 GW. Its creators say the platform can be used to track unregistered solar rooftop capacity.
New technique to geo-label PV modules in utility-scale solar parks
Scientists in Morocco have developed a method that uses the metadata of PV plants’ infrared images to label them geographically. The automatic database can then be used in deep learning models and significantly reduce the time required for data labeling.
Copper doping boosts manganese cathode stability in sodium-ion batteries
Researchers at the Tokyo University of Science have shown that using copper can eliminate defects in sodium manganese oxide battery types, boosting battery cycle life.
Fraunhofer ISE achieves 40% efficiency for indoor III-V solar cell
The PV device is based on a indium gallium phosphide absorber with an energy bandgap of 1.9 eV. It is intended for use in autonomous Internet of Things (IoT) applications that operate indoors without an external wired power supply.
BBDF 2025: Warranties, safety key to achieving battery quality
Tech specialists at the “Technological advancement and risk mitigation” panel identified safety and warranties as the key pillars of quality in the battery storage sector. Speakers discussed how these factors shape component selection and long-term project viability.
