Sub-nanometric particles to stabilize lithium-oxygen batteries
The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.
Shielding PV against Earth’s magnetic field
Researchers in Kenya are seeking to reduce the influence of the Geomagnetic field on PV panel performance by replacing aluminum module frames with a steel cage. They have specified they have been unable to quantify costs related to the solution, and that more research is needed.
Affordable hydrogen-fueled flight possible in 2035
Hydrogen-fueled aviation has a realistic chance of helping the sector achieve climate goals, according to a European Union-commissioned study.
Heterojunction MWT solar module based on 23%-efficient cells
Scientists in the Netherlands have claimed that a heterojunction metal wrap-through solar module they are designing could offer a 4% performance improvement over conventional heterojunction panels.
India can become electric vehicle manufacturing hub within five years says roads minister
The industry needs to cut a dependence on lithium-ion battery imports from China, according to Nitin Gadkari, who said the government is looking to support research into alternative technologies.
Self-cleaning PV system with active cooling tech
An international research group has developed a self-cooling PV system featuring a 250 W 60-cell polycrystalline module and a thermal collector attached to the back side of the panel. The cleaning tech is based on a microcontroller programmable integrated circuit, which controls a rotating DC motor.
New chemistry promises better lithium sulfur batteries
Scientists in the U.S. have developed a new cathode chemistry for lithium-sulfur batteries, which they say promises to overcome performance issues stemming from sulfur’s low conductivity and tendency to react with lithium.
European consortium bid to bring 25.4%-efficient heterojunction-IBC solar cell into mass production
The EU-funded Nextbase project aims to manufacture heterojunction, interdigitated back-contact solar modules for less than €0.275/W. Solar panels featuring the Nextbase cell tech are expected to have a conversion efficiency of 23.2%, according to the European Commission.
Low-cost direct solar-to-hydrogen ambitions see the light
The road to cheap hydrogen production is riddled with potholes and energy losses. Researchers in Australia have demonstrated rethinking solar technology and skipping electrolysers could hold great promise for reaching the hydrogen holy grail.
Parabolic bifacial module with active cooling system
Scientists in Morocco have designed a new bifacial module with a cooling system, based on bifacial parabolic solar cells that are connected to each other via tubes for panel cooling. They are now patenting the tech, but have yet to manufacture an initial prototype.
