Conceived by a Dutch research group, the proposed system is intended to store surplus renewable electricity via hydrogen generation and battery storage, with the latter being used only when hydrogen generation is not immediately available. Despite its high initial costs, the system can reportedly offer stable operation.

Researchers in China have outlined a new surface engineering strategy to build low-cost solar cells without a hole transport layer. The devices were treated with benzoylcholine halide to reduce non-radiation recombination and achieved remarkable efficiency and stability.

Researchers in China have developed a model to predict lifetimes of heterojunction (HJT) modules made with ultraviolet cut-off polyolefin elastomer (POE) encapsulant. The approach considers factors such as temperature, humidity and UV irradiation.

Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.

IEA PVPS is about to start a new format for expert engagement: an Action Group on Agrovoltaics; a collaborative effort to harness the synergy between agriculture and solar energy generation. Through international cooperation and interdisciplinary engagement, the group aims to unlock the potential of agrivoltaics, optimizing land use efficiency, enhancing agricultural resilience to climate change, and fostering social consensus towards solar energy development.

Swiss researchers have engineered a device that uses solar energy to heat to more than 1,000 C. The technology could make it possible to use solar energy to decarbonize energy-intensive industries that require high temperatures for production processes.

The Bridgestone World Solar Challenge has announced a new set of dates for for the 2025 edition of its unique 3,000 km solar car race across the Australian continent, along with some regulation changes.

Slovakian scientists have developed a novel hydrophobic, antireflective coating for solar glass with a silica-titania thin film as the bottom layer and an inorganic-organic upper layer made of silica modified with triethoxy(octyl)silane. This new coating increases glass transmittance by 7% compared to uncoated glass.

The researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.

An Australian community group has launched a new guide to help solar developers to improve biodiversity on project sites and build trust in neighboring communities without compromising PV generation capacity.
