Technology and R&D

Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.

Scientists led by the University of New South Wales have looked into the long-term degradation of silicon-heterojunction. Their findings suggest that illumination at high temperatures could actually improve cell efficiency, but also risks activating multiple light-induced degradation mechanisms if not carefully controlled.

Researchers say the technology could help drive clean energy deployment in countries with limited grids or in isolated, coal-based energy systems. According to their model, Kosovo could see a strong increase in wind and PV capacity if power-to-heat is coupled with thermal energy storage for fixed-capacity district heating.

Indian and Malaysian scientists have developed a new cooling system featuring an assembled back-channel attached on the rear sides of solar panels, to channel flows of titanium oxide and water. They used a 0.6% nanofluid concentration – the optimum value of nanoparticle concentration in water.

Iasol has developed a new way to protect solar plants in windy conditions. The Spanish developer said the solution barely has an impact on project costs or output, while preventing expensive damages.

With $32 million in series B funding and an ever-growing project pipeline, air-based tracker startup, Sunfolding, is hoping to increase its hold in the tracker market with tech that’s simple, light and can be installed on terrain previously thought untouchable.

Scientists at Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) have used intense pulsed light (IPL) processing for the development of a busbarless silicon heterojunction solar cell. ILP processing is roll-to-roll technique for rapid thermal processing of various thin films.

In a national park in Chile, a hydropower plant has been combined with a solar system and battery storage to replace diesel generation.

Scientists have developed a new micro CIGS cell by using an area-selective electro-deposition process as a material-saving technique. It has a conversion efficiency rate of 5.2% and a high open-circuit voltage.

Jolywood is one of the few PV manufacturers, who has placed its bet on TOPCon technology. Instead of focusing on the simplicity of the production process, Jolywood believes the conversion rate is more critical. With years of efforts, the company has established its leading position among TOPCon players. During the SNEC 2020 in Shanghai, pv magazine had the opportunity to interview Liu Zhifeng, Vice General Manager of Jolywood, and listened to his views on some hot topics, especially the cell tech route.
