Singaporean scientists have developed a special device that prevents the formation of dendrites in lithium-ion storage. The additional layer they created works as an interface on behalf of the negative electrode, to exchange lithium-ions with the positive electrode.

In the third of a series of four blogs, solar pioneer Philip Wolfe lists the world’s largest solar parks. In these articles, a “solar park” is defined as a group of co-located solar power plants.

As solar deployment increases, concerns about price cannibalisation continue to be more and more relevant. Large-scale solar generation during midday hours may result in curtailment or unprofitable wholesale power prices. As supply increases, the economic viability of solar PV projects could fall into question.

Buildings are considered to be a major driver of emissions. In addition to the predicted billions of square meters of space that will be built across the world over the next decade, most developments standing today will still be around in 2050. Thus, retrofitting existing structures is seen as a key sustainability target. In the fourth quarter of 2021, pv magazine’s UP Initiative will focus on the role that solar and energy storage can play in greening the world’s urban spaces.

The past week saw more records broken in the National Electricity Market (NEM), with instantaneous renewable generation hitting a record 59.8% in the afternoon of Sunday 19 September 2021, before breaking 60% for the first time on Monday 20 September 2021. Sunny weather across both days meant rooftop solar made up around half of renewable generation at this peak output, reducing operational demand and suppressing prices during the day.

The Australian-Singapore group behind a proposed 20 GW solar PV farm and 42 GWh battery energy storage project being developed in Australia’s remote far north has hinted other, similar-sized projects are already in the pipeline.

Representatives from some of Australia’s most prominent renewable energy companies have united in their criticism of the Energy Security Board’s proposal for consumers to pay conventional generators such as coal and gas power plants an extra fee for their capacity, not just the actual power they produce.

The German research institute has unveiled a novel interconnection technology for shingled PV modules that eliminates the need for electrically conductive adhesives and screen-printed busbars. It consists of an 8-μm-thick aluminium foil that is joined to the silicon nitride (SiNX) passivation via laser metal bond (LMB). When integrated in a solar module, the efficiency of the new interconnector improved by 0.7%.

The last of the New South Wales coal-fired power plants will be shut by 2040 at the latest after electricity gen-tailer EnergyAustralia announced it would bring forward the closure date of its 1.4 GW Mt Piper power station by two years.

Vattenfall is leading a Dutch consortium in a research project to assess whether agrivoltaics is also compatible with strip cropping. The company’s head of Solar Development NL, Annemarie Schouten, spoke with pv magazine about the first 0.7 MW pilot project under development in the northern Dutch province of Flevoland.
