Researchers in Korea have proposed a new design for dividing and bonding which is said to provide higher efficiency from fewer fingers. The number of fingers optimized for division into five cells was 128 and for three, 171. Five offer power conversion efficiency of 17.346% and three 16.855%.

The public charging points will be installed in the provinces of North Holland, Flevoland and Utrecht. The oil giant said they would all be powered by renewable energy.

A minor concern it may be, compared to the tragic loss of life, livelihoods and biodiversity caused by the bushfires still ravaging parts of Australia, but reduced output by PV systems due to smoke haze is an unwelcome bi-product of blazes that have burned at a scale and ferocity never seen before.

The raised renewable energy ambition has been dismissed by the domestic solar association, which accuses president Miloš Zeman of wanting to destroy the Czech PV sector. In 2019, the country added only 7 MW of new PV installations.

A study from Finland’s Lappeenranta University of Technology has predicted solar and other renewables can provide a global energy jobs revolution – just as four European operations revealed recent struggles.

Researchers from Saudi Arabia’s King Abdullah University of Science and Technology have created flexible solar cells made of crystalline silicon. They claim to have stretched a crystalline silicon cell’s surface by around 95% while maintaining conversion efficiency of around 19%.

An international research group led by CIC EnergiGUNE, a Spanish research center, is designing new redox organic flow batteries. The researchers claim the batteries will offer longer duration, as well as higher power and energy densities, in a more environmentally sustainable format. The European Commission provided €3.8 million in funding for the initiative.

Four bids have been lodged for 100 MW projects and fifth for a 90 MW facility, all in peninsular Malaysia, to indicate the 500 MW tender will fall short of its intended capacity. The lowest solar power price lodged is for $0.042/kWh.

The UAE Federal Electricity and Water Authority is seeking expressions of interest to enable it to pre-select independent power producers for the project. The plant will be owned 60% by the government of Umm al-Quwain and the electricity authority, with the successful developer owning the balance.

Following its decision to switch from fixed feed-in tariffs to reverse auction bidding for the setting of solar incentives, the Vietnamese government has decided to devote the first two pilot auctions to floating PV. A first procurement exercise, for a project which could reach 100 MW of generation capacity, will be held this year.
