Modules & Upstream Manufacturing

Opinion is divided over the urgency of addressing the issue. While some developers feel the 25-year lifetime of modules offers plenty of time to prepare an action plan, other industry voices claim Indian-made products don’t last half that long and one recent report pointed out waste is already piling up thanks to defects and faulty installation.

In an update to its International Technology Roadmap for Photovoltaics, German engineering association the VDMA notes standardization of wafer size is a topic of great interest to the country’s PV equipment manufacturers, and modifications to lines will be needed to process wafer pieces larger that 161mm.

Insolvency proceedings have been opened against the assets of the German thin-film solar manufacturer. A proposed reorganization failed because investors did not provide sufficient capital. Some 180 employees will lose their jobs.

In a white paper published this week, Chinese module maker Longi Solar shares six months of data from a testing site in India that was built in cooperation with German testing institute TÜV Rheinland. The results show energy yield gains of around 20% for both bifacial mono PERC and n-type modules.

Research from Canada has revealed liquid-like lineshape dynamics in cesium-lead iodide perovskite nanocrystals. The findings could be used to produce cheaper and more efficient perovskite cells, researchers claim.

A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.

The mono giant has announced the latest aspect of a strategy to massively increase production capacity which is currently set to cost around $3.32 billion. Longi last week issued $710 million of new convertible bonds for investors.

Korean conglomerate LG reports increasing demand for its high-efficiency PV products in key markets while Kyocera said its solar business is improving profitability. Panasonic posted a slight increase in sales for its PV segment, including solar manufacturing.

Enormous order intake is ensuring high production capacity utilization at the German PV equipment provider. The company said demand was particularly strong for high-efficiency solar cell production equipment in Asia. Thus far this year, however, that has not been reflected in the balance sheet.

The Swiss solar equipment supplier today fought off an attempt by its largest single shareholder to have a representative appointed to its board and to have its executive pay regime reviewed. Victory in that battle may secure the company some wiggle room, but the war over corporate strategy appears far from over.
