Flexible solar panel for vehicle-integrated applications
Called SolFlex, the frameless panel is based on 22%-efficient solar cells and is designed for high, one-sided heat load. The standard product measures 100x100x2.9cm, weighs in at 3.4kg, and has a power output of 170 W.
German researchers want to reduce manufacturing costs for electrolysers by more than 25%
A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolysers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.
Fraunhofer CSP develops repair process for PERC solar cells
The performance of the solar cell contacts can be improved with laser-assisted current treatment. The process does not damage the solar cells but only optimises faulty semiconductor-metal contacts.
Mini organic solar module with 13.94% efficiency
The panel is based on 14.9%-efficient organic PV cells with a surface of 1.1 cm2 that the same research group unveiled in September 2020. The solar cells were interconnected using laser structuring.
Coupling PV-powered electrochemical water splitting with battery storage
A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.
Lithium-metal battery with capacity retention of 88% over 1000 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
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 modelled the large-scale production of microbial biomass by combining ground-mounted photovoltaics, air, water, and nutrients.
Meyer Burger plans to launch solar PV roof tiles in 2022
The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.
Arc-shaped PV system for agrivoltaics from Germany
The PV mounting system was developed by Germany-based Goldbeck and will initially be available in the Netherlands from 2022. The company will test the new technology in a 45 MW PV project.
