Israel’s Phinergy to present Tata car powered by its aluminum-air battery
The electric car powered by Phinergy aluminum-air battery will be on display in Auto Expo India 2023 at the booth of IOC Phinergy (IOP), a joint venture of Phinergy and State-run fossil fuel giant Indian Oil Corp.
New algorithm to identify underperforming strings in PV systems
German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.
All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency
Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.
