Nitrogen-doped carbon nanodots for more stable, efficient perovskite solar cells
A Spanish-Italian research group was able to improve the efficiency and stability of a standard perovskite solar cell by adding nitrogen-doped carbon dots as an additive. The carbon dots were then blended with the perovskite precursor solution at two different concentration levels and both were deposited by spin coating on the perovskite layer.
UK startup develops Brayton pumped thermal tech for renewables storage
UK-based Synchrostor has developed a new pumped thermal energy storage (PTES) system. It is purportedly fully reversible in 30 milliseconds and can achieve a round-trip efficiency of around 70%. The proposed storage technology can also provide grid inertia and ancillary services.
Trina launches grid-scale storage solution
Trina Storage’s new 2.1 MWh DC All-New Elementa solution is a modular LFP battery cabinet with a plug-in concept to connect multiple units. The company is ramping up battery manufacturing capacity to strengthen vertical integration, given supply chain risks throughout the world.
Novel way to turn semi-finished thin-film solar modules into colored BIPV panels
German scientists have developed a way to cut semi-fabricates into desired shapes and then apply a conductive oxide-metal-oxide electrode with the preferred color. They can structure the elements into modules via the backend interconnection process.
1 kg balcony solar module you can install yourself
German startup We Do Solar is gearing up to deliver its first balcony solar modules to customers in the next three weeks. pv magazine caught up with one of the founders at Intersolar Europe 2022 to learn more about the kit, which features a 1.6 kg flexible solar module people can install themselves, and three innovative business models.
Alliaverre to produce solar glass in France
Alliaverre wants to move a 600 MW solar glass plant to Amiens, France, to reduce European customer delivery times, as it faces rising shipping prices and manufacturing constraints in Asia.
