Modules & Upstream Manufacturing

Analyst Johannes Bernreuter says most of China’s polysilicon production capacity is in regions away from the center of the coronavirus outbreak. He added, however, 27% of the nation’s 510,000-ton annual polysilicon capacity could be affected.

The coronavirus outbreak in China could raise solar module prices in the near term as manufacturers have already begun experiencing wafer and solar glass shortages. Production rates are also being affected by an extended new year holiday introduced by the authorities as a measure to deal with the virus, and the requirement workers from infected areas quarantine themselves for two weeks.

Electronics corporations Panasonic, Kyocera and LG have filed results for the nine months to December 31. All three reported uplifts because of their solar activity and LG has said it will dive deeper into energy storage. Panasonic is deepening its commitment to automotive batteries through a new joint venture with Toyota.

Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules.

The efficiency of the cell, made with a standard M2 wafer, was raised around 0.7% by using an improved busbar-free screen printing metallization process based on heterojunction processes developed with manufacturing equipment provided by Swiss specialist Meyer Burger.

The move, by Taitong Industry Ltd, will come as a fresh blow to the Chinese module manufacturer, which twice failed to go public – in the U.S. and China – and whose project development business suffered a battering in China when Beijing reined in subsidies in 2018.

In 2020, perovskite cells could pass the IEC tests intended for the standardization of solar modules, and in 2022, they could even be mass-produced. In an interview with pv magazine, Tom Aernouts explains the status of work on the new PV technology. He is a research and development manager for thin film photovoltaics at the Belgian research institute Imec.

Solarwatt’s Vision glass-glass solar PV modules have pushed the technology’s resilience even further after passing cyclone testing in Darwin, Australia.

Italian manufacturer Sunerg has developed a solar module for BIPV applications which is said to offer a wide range of options to better match the architectural vision and the design of a building. The 275 W monocrystalline PERC panel is available in mahogany brown, reddish brown, bottle green and black-grey.

Researchers from Hungary have analyzed the thermal behavior of different types of PV module via thermography, and claim to have shown that theoretical models are insufficient to measure the maximum, minimum, and average temperatures of the panels. According to their analysis, glass-glass modules without frame showed the highest temperatures, while the lowest temperatures were measured for polycrystalline glass-backsheet panels with frame.
