Fraunhofer ISE reaches legal settlements with seven inverter manufacturers who infringed its patent
In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.
Recycled silicon used in 19.7% efficient PERC solar cells
Led by German research institute Fraunhofer ISE, the consortium has built the solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels. The silicon is recycled through a technique conceived by German specialist Reiling GmbH & Co. KG and the Fraunhofer Center for Silicon Photovoltaics CSP.
Industry heavyweights look to solid-state battery cells, resources, and recycling
Mercedes-Benz has teamed up with ProLogium to integrate solid-state battery technology into a range of vehicles; Panasonic and Toyota launched an industrial-academic collaborative research program concerned with battery resources and recycling; and LG Energy Solution plans to spend $2.1 billion with GM to build another EV battery plant in the US.
U.S.-based EV charger maker enters European market

Center notches 29.80% efficiency for perovskite/silicon tandem solar cell
The solar cell is based on a nanotextured front side and a back side with a dielectric reflector.
A promising new design for shingled solar modules
Research finds that the energy yield of a novel approach could almost double that of standard shingled cell interconnection under random shading conditions.
Flexible solar panels for vehicle-integrated applications
The frameless panel is based on 22% efficient solar cells and is designed for high, one-sided heat load.
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%.
Crystal arrangement results in 1,000x more power from ferroelectric solar cells
Researchers discovered a ferroelectric crystal lattice that increases a solar cell’s photovoltaic effect by a factor of 1,000.
German start-up offers 5.2 kWh AC battery that works without inverter
