A silver-oxide zinc battery — flexible, screen-printed and with 20 times the capacity of Li-ion
A team comprising researchers from the University of California San Diego and micro battery developer ZPower have developed been busy in the lab. The result is a flexible battery with highly competitive electrochemical features and the option to manufacture at low cost with screen-printing.
Semi-transparent dye-sensitized solar module with 8.7% efficiency
The mini-panel showed a short circuit current of 58.1 mA, an open circuit voltage of 3.63 V, and a fill factor of 58.26%. It has a power output is 122.9 mW and an active area of 14 cm2.
New safety standard for PV hazard control
The American National Standards Institute (ANSI) and the Standards Council of Canada (SCC) have approved the new UL 3741 standard.
Relectrify posts results from second-life battery systems
After more than a year of testing, Relectrify has released the interim results of a pilot that combines repurposed batteries from Nissan Leaf vehicles with proprietary inverter technology.
Australian PV plant tests 2 MW/8 MWh vanadium flow battery
Australia’s first utility-scale vanadium flow battery will be built in South Australia. It will demonstrate the tech’s potential to provide energy and frequency control ancillary services for the national grid.
European Commission proposes minimum sustainability thresholds for batteries
The world’s second largest battery market is mulling strict regulation of what type of products can be sold within it. The bloc wants to tighten rules on using hazardous materials and would encourage circular economy approaches. The scope of the commission’s proposal would also affect the design of devices, with phones, laptops and other portable gadgets without removable batteries set to be prohibited.
Italy’s 2050 decarbonization plan needs 6 GW of new PV capacity annually
A recent forum held by Italian trade body Italia Solare has shown that Italy needs to streamline its large scale PV sector if it wants to reach its energy and decarbonization targets.
Photovoltaic-thermal district heating networks are feasible
A group of scientists and companies in the Netherlands has tested a PVT heating concept in a green district and has found that the proposed design, which is also based on underground storage and the use of heat pumps, is technically and economically feasible.
Chinese polysilicon makers driving industry’s second great consolidation
The 275,000 metric tons of annual polysilicon production facilities pushed out of the industry by the expansion of big Chinese producers is more than double the capacity lost in the last great poly market shake-out, between 2010 and 2013.
Meyer Burger and Ecosolifer sign settlement agreement on heterojunction cell line
The two companies have concluded a settlement after several years of stalling. Ecosolifer will pay for part of the cell production line ordered in 2015 but Meyer Burger will incur a net loss of almost CHF2 million.
