An Italian startup has developed a luminescent solar concentrator technology that can be integrated with active architectural elements and windows. The technology is based on nanoparticles known as chromophores, which decouple the absorption and light-emission processes, thanks to appropriate engineering. The company claims it has achieved a conversion efficiency of up to 3.2%, with a degree of transparency in the visible spectrum of around 80%.

South Korean scientists have produced an organic, hybrid-series tandem PV device that combines quantum dots and organic bulk heterojunction photoactive materials. They claim that the cell has the highest efficiency among all reported colloidal quantum dot cells, including single-junction devices and tandem devices.

Chinese PV heavyweight Canadian Solar has announced an offtake deal for its Gunnedah solar project with e-commerce giant Amazon in the Australian state of New South Wales. The e-commerce giant also plans to build a 50 MW solar plant near Zaragoza, in eastern Spain.

Optimizer manufacturer Alencon has published a paper outlining the technical challenges to replacing the largely obsolete and frequently failing 600 V central inverters used in older PV projects.

The Chinese polysilicon giant’s net income fell nearly 23% year on year to $29.5 million in fiscal 2019, even though it posted a 16% year-on-year jump in revenue to $350 million. It expects its polysilicon output to soar in the year ahead, despite the threat posed by the coronavirus outbreak.

Italian company Ecoprogetti will supply the production equipment to Bahrain-based module producer Solartecc. Output is set to begin in the third quarter.

Liander will apply a grid congestion management system in the Gelderland province from the autumn. The measure is intended to reduce the number of solar and wind power projects waiting on new grid capacity.

The scramble for new battery solutions is accelerating as researchers from Singapore tout an electrolyte which which they say produces highly stable lithium-sulfur batteries that maintain performance metrics – a task which has proven tricky thus far.

The Swiss PV equipment supplier posted the loss for 2019, citing increasingly fierce competition in China, and plans to continue a strategic realignment of its business with the options including the establishment of a European PV manufacturing operation.

A convertible bond issuance by Valoe Corp is due to expire on Sunday and the board has already been forced to sign up for more than 40% of the investment. The module maker, which is still attempting to pay for a cell line acquired from Solitek last year, has been announced as a technology partner by Munich-based Sono Motors.
