Redox flow battery powered by perovskite solar cells
An international team has developed an integrated solar flow battery which has been suggested as ideal for off-grid locations. The device, which combines energy conversion and storage in one unit, can be used for lighting and recharging cell phones.
Chinese PV Industry Brief: 10 GW module-inverter tender and 300 MW in Liaoning
JA Solar began work on a 300 MW solar plant in Liaoning province last week, while state-run Huaneng launched a fiscal 2020 tender for 5 GW of inverters and another 5 GW of PV modules.
Switzerland deployed 332 MW of solar last year
Cumulative solar generation capacity reached 2.5 GW last year, enough to meet 3.8% of electricity demand.
A closer look at Jinko’s 565-585 W panel
The module – which measures 2,411×1,134×35mm, weighs 31.1kg and features 156 p-type monocrystalline cells – is available in five versions with power outputs of 565-585 W and efficiencies of 20.67-21.40%. Jinko says the Pro Tiger series will become the company’s main revenue stream in 2022, surpassing the Tiger 475 W panel.
IBC solar cell with 25% efficiency
Australian researchers have revealed a new cell that builds on an earlier 24.4%-efficient device. The upgrade was achieved with an oxide-nitride-oxide passivation stack which optimized diffusion and contact-area fraction, plus improved texturing with a monoTEX surfactant.
Solar causes highest power peaks under mixed-cloud conditions
Dutch researchers have shown that power peaks caused by solar generation may be stronger under partial cloudiness than clear skies. According to their findings, mixed-cloud conditions can enhance PV power production due to light reflected off clouds, as well as their intermittent shadows on arrays, which reduce module temperatures.
ArcelorMittal seeks solar PPAs for 150 MW in South Africa
The steel manufacturer aims to sign power purchase agreements for six operational sites in Vanderbijlpark, Newcastle, Vereeniging, Pretoria, Thabazimbi and Saldanha.
LF Energy and the pursuit of a modularized grid
LF Energy has launched its Digital Substation Automation Systems initiative, in hopes of creating a more modular, flexible and resilient grid. It aims to make interoperable substations that are both hardware and software agnostic.
Tunisia’s first floating PV project
The national utility has signed an agreement with the Total-owned Qair business formerly known as Quadran International for a 200 kW floating solar power plant and a study of Tunisian potential for the technology.
Ikea extends PV offer to France
The furniture brand has begun offering solar panels and systems online throughout the country. French solar company Voltalia will be its strategic partner for the sale of its Solstrale modules.
