Modules & Upstream Manufacturing

While lacking the swarming crowds of previous years, the 2019 SNEC in Shanghai remained a focal point of the global PV industry when it comes to industrial solar cell and module manufacturing and technology. Here are five hot technology takeaways from the pv magazine team on the show floor and conference sessions.

A research paper from scientists at the U.S. National Renewable Energy Laboratory outlines a new approach to the production of gallium arsenide based cells. The approach, termed ‘germanium on nothing’, could enable the cost effective, high volume production of PV cells based on III-V materials such as gallium arsenide.

There was plenty of innovation on display at this year’s SNEC, which closed yesterday afternoon at the Shanghai New International Expo Center. The three-day exhibition ran from Tuesday to Thursday, was well attended and still ranks as the world’s largest solar energy trade show.

German customs officers executed two arrest warrants during the Smarter E show in Munich. The public prosecutor’s office in Nuremberg-Fürth also confirmed another arrest, connected to an existing investigation of a Chinese PV manufacturer. The arrested executives were allegedly involved in commercial smuggling of solar modules, the customs authorities and prosecutor told pv magazine. The authorities believe minimum import prices for crystalline solar modules from China, in effect until September, were circumvented and millions of euros in payments were evaded.

In the petition, the manufacturers claim their Korean rival’s patent assertions should be declared invalid as there is evidence the innovations they refer to were either not new or were obvious steps forward.

The polysilicon, ingot, wafer, cell and module giant made two huge announcements this week, with plans to almost double wafer manufacturing capacity just as it moves to sell off its PV project development business to state-owned energy giant China Huaneng Group.

In a conversation with pv magazine, REC vice-president for sales in the EMEA region Ivano Zanni describes the new strategy of the Norwegian manufacturer following the launch of its high-efficiency, half-cut mono n-type heterojunction module. REC expects annual production capacity for the panels at its factory in Singapore to increase to 600 MW by the end of next year, and that the company’s total capacity will reach 2 GW.

New modules incorporating American company 1366 Technologies’ 3D direct wafers were unveiled yesterday at the SNEC trade show in Shanghai. The prototype modules are produced by Korean manufacturer Hanwha Q Cells. The two companies have a strategic partnership going back several years, and are ramping up a wafer factory near Q Cells’ module facilities in Malaysia.

The modules will be used by U.K. developer Solarcentury for its Cabrera and Talayuela Solar projects in southern Spain.

The former director of Fraunhofer ISE will be officially elected at a general assembly planned for September. The ESCM wants a strong Europe to be part of the Fourth Industrial Revolution and also pay attention to sustainability.
