German scientists develop solar facade with 50% higher yield
The three-meter prototype consists of nine panels based on an aluminum compound. The PV elements of the facade can be tilted to capture more sunlight.
Energy community provisions for Italy
New measures introduced by the government allow households, businesses and public entities to produce and trade clean electricity in low-voltage grids. The new framework is open to power projects with a generation capacity no larger than 200 kW.
More postponements due to Covid-19
The list of major solar industry events put on hold due to the Covid-19 virus is lengthening. Today, Solar Solutions Amsterdam became the latest event planned for this month and next which the organizers must reschedule for later in the year.
UK includes solar in new generation capacity auction
The announcement by the Department for Business, Energy and Industrial Strategy of an auction which will include solar next year appears to back prime minister Boris Johnson’s claims to be serious about the nation’s net-zero carbon ambition.
A commercial bifacial HJT solar cell with 24.1% efficiency
The cell is being manufactured by Switzerland-headquartered Ecosolifer with a manufacturing line provided by heterojunction specialist Meyer Burger at a 100 MW factory located in Hungary. The claimed efficiency is yet to be confirmed by an independent party.
Speeding up storage with pseudocapacitors
Scientists at Germany’s Helmholtz Zentrum Berlin have made a discovery they say could greatly increase the energy storage capacity of titanium-based ‘MXene’ pseudocapacitors, ultimately leading to faster-charging batteries. The group found adding urea molecules between MXene layers increased the material’s storage capacity by up to 56%.
Achieving 21.2% efficiency in a perovskite cell thanks to food additives
South Korean scientists have developed two perovskite solar cells based on a polymer made with peppermint oil and walnut aroma food additives, respectively. The new dopant‐free hole transport polymer is said to enable longer durability of the devices and to prevent lead-leakage.
Lithium miner expects profits to plunge 65%
Ganfeng Lithium blamed a falling lithium salt price for its expected woes, rather than the effects of the COVID-19 outbreak on operations which it spelled out last month.
A plug-and-play solar-powered battery back-up solution for the home
The OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a ‘hassle-free’ solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.
A new PV emulator to evaluate the I-V profile of solar panels
The device is based on a state-feedback adaptive control system in a real-time controller. According to its developers, it can achieve good dynamic response and boasts better bandwidth than current commercial alternatives.
