Lithium-metal battery with capacity retention of 88% over 1,000 cycles
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%.
SMA warns of electronic component shortage
In the first half of the year, the German PV inverter maker recorded high demand for its inverters and storage solutions from the residential solar segment. The effects of the corona pandemic, however, have had an impact on the commercial segment and, although a recovery in demand is expected in the second half of the year, SMA said it is currently dealing with delivery issues.
Germany needs 446 GW of PV for 100% renewables scenario
According to a new study by the Fraunhofer ISE, there is more than enough space for this huge growth in installed solar PV capacity. Indeed, if all available areas were used for PV – including opencast mines, facades, roads, and agricultural land used in combination with solar power generation – over 3,000 GW could be deployed.
German manufacturer unveils 10-busbar, half-cell PV modules
Bauer Solartechnik GmbH has released its new 400 W and 405 W BS-M10 PV panel series for rooftop projects.
Facade BIPV modules designed with stone veneers
Developed by a German group of scientists, the panels are considered an ideal solution for aesthetically demanding applications in buildings with stone facades. Although their power yield is more than halved compared to conventional modules, the modules can also be used as partial shading walls or semi-transparent roof elements.
Higher polysilicon prices improve Wacker’s financials
The Munich-based chemical company was also able to significantly increase sales volumes for its polysilicon segment. In June, Wacker Chemie raised its forecast for the full year substantially.
Crystal arrangement results in 1,000x more power from ferroelectric solar cells
German researchers developed a lattice arrangement of three different layers of ferroelectric crystals that created a powerful photovoltaic effect.
Solar-powered large scale microbial food production
Producing nutrient-rich microbes with solar PV has the potential to produce more food with fewer resources, according to a German research group that modeled the large-scale production of microbial biomass by combining ground-mounted photovoltaics, air, water, and nutrients.
Germany installed 2.75 GW of PV in first half of 2021
In June alone, new PV systems totaling 430 MW were connected to the German grid. The country’s cumulative operational PV capacity reached 55.3 GW at the end of June.
The Hydrogen Stream: GCL will use Ethiopian natural gas to feed its ammonia and blue hydrogen
Plus there is news this week of a green hydrogen tie-up in India, plans for another German production facility, and of new hydrogen transport networks for Switzerland and the U.S.
