The frameless panel is based on 22% efficient solar cells and is designed for high, one-sided heat load.
German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.
Researchers discovered a ferroelectric crystal lattice that increases a solar cell’s photovoltaic effect by a factor of 1,000.
Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.
The battery maker published test results indicating the longevity of its storage systems after extended use.
The Baywa group will maintain a 51% stake in the German renewable energy company.
After ten secretive years, several hundred million dollars spent, and the efforts of hundreds of scientists and engineers, QuantumScape went public on a video call today with the performance results of its solid-state battery — and its potential impact on the electric vehicle industry.
A British-German research team claims that organic PV technologies may become mature enough to compete with crystalline silicon and thin-film products not only in BIPV, but also in power generation in the electricity market. In order to get there, however, organic PV products will have to achieve higher efficiencies.
Despite the coronavirus pandemic, the photovoltaic inverter maker grew its revenue compared to the previous year.
