Spanish solar renaissance lifts world to record year for large scale projects

A global ranking of large scale solar project capacities indicates prominent roles for a resurgent Spain, behind the usual top three of China, the U.S. and India, with Australia and the Netherlands also on the rise. There were disappointing returns, though, for the U.K., Italy and Canada.

‘Falling solar module costs are behind us’

Canadian Solar is pivoting towards energy storage and is preparing to IPO its manufacturing and Chinese solar project activity in China, under the CSI Solar operation, by July.

Sunday read: History repeats

“Unprecedented” was a term widely used in 2020, as the world grappled with the Covid-19 pandemic. The same word can be similarly applied to the plans and investments in production capacity announced by Chinese PV manufacturers right across the supply chain. But what shape are these expansions taking and what is driving this renewed confidence? Vincent Shaw reports from Shanghai.

An aluminium battery that can charge in a fraction of a second

Scientists in China and the United States investigated the inner workings of aluminium-ion batteries. With new insights into mechanisms at work within the battery during cycling, the group was able to demonstrate a battery capable of ultrafast charging, with the highest capacity so far reported for an aluminium battery.

Sunday read: Levelling the playing field

Tensions are heating up throughout the world over the issue of forced labor. Calls are increasing for supply chain transparency, and recently published EU draft legislation on corporate due diligence and accountability should improve upon the currently available voluntary measures, which have been described as largely ineffective. With this in mind, pv magazine’s UP Initiative will spend the second quarter of 2021 looking at what solar and energy storage companies can do to lead by positive example when it comes to the workers who are involved in the production of their products and services.

Saturday read: Clever by half

Enhanced module appearance and power output can be achieved by a smart cell interconnection technique Longi is employing in its Hi-MO5 module series. But as with all new technologies, there are potential pitfalls.

Trina launches 670 W solar panel

The latest product in the Vertex series from the Chinese manufacturer has a power conversion efficiency of 21.6%.

Sunday read: Unlocking lightweight, flex applications

Not all rooftops can bear the weight of glass PV modules. Some others have curves and shapes ill-suited to uniform, bulky panels. Flexible modules have long been advanced as the solution here, however the keys to unlocking this potential have proven elusive.

Perovskite solar cell with cesium-titanium dioxide nanotubes

A global research group has developed a perovskite PV cell with titanium dioxide nanotubes doped with cesium. It purportedly offers better short-circuit current and power conversion efficiency than cells without cesium nanoparticles. They say it has optimal thermal stability under temperatures up to 800 C.

Trina Solar enters storage business

The module manufacturer’s new storage unit, Trina Storage, aims to create innovative solutions for the combination of photovoltaics and storage, grid services and other applications.
