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.

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

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.

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.

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.

Large swaths of low-cost land: check. Lots of sun and wind: check. The ability to transport green hydrogen cost-effectively to energy importing economies: check. Then you’re in the race to become one of the “renewable energy superpowers” of the low-carbon economy. A growing number of countries are assessing their renewable resources and natural attributes and positioning themselves to become green hydrogen exporters. However, not all are created equal.

At present, China accounts for almost 75% of global lithium-ion battery manufacturing capacity and this share is set to increase through the short term with its build-out of new facilities. And although the US and Europe are enacting policies to encourage domestic battery production, there has been a distinct lack of support for investment in the supply and refining of the raw materials to achieve this. In China, the opposite holds true. 

The tide of clean energy facilities planned under the city’s next five-year strategy was revealed by Hong Kong-listed polysilicon maker Xinte Energy, which has signed a framework agreement to construct 200,000 tons of manufacturing capacity near Inner Mongolia’s largest city.

Energy consultancy DNV GL has published new results comparing the performance of modules based on 166mm, 182mm and 210mm silicon cells. The assessment compares Trina Solar’s Vertex modules, which use the largest cell dimension, with unnamed competitors utilising the other two sizes. Results from system simulations show a clear advantage for the two larger sizes, with 210mm edging ahead in terms of levelised cost of electricity.

A new report from Wood Mackenzie suggests costs of front-of-the-meter battery storage systems in the Asia Pacific region could decline by 30% by 2025. The declining costs are already having a palpable impact as 2021 has opened with a slew of large-scale battery project announcements.
