The Linde Group said that thin film start-up Malibu, a joint venture between energy company  E.ON, and Schüco that uses Applied Materials ‘SunFab’ technology, will employ Linde’s fluorine technology at its 40MW facility in Osterweddingen, Germany. Linde won the “Green Solar Manufacturing” Cell Award for the technology at a ceremony held last week during Intersolar in Munich.

Malibu will be the world’s first thin-film solar module factory that completely eliminates the use of nitrogen trifluoride (NF3), a greenhouse gas with a significant global warming potential, from the manufacturing process.
 
“Not only does the F2 cleaning process eliminate a major source of potential greenhouse gas emissions for our thin-film solar panels, it also speeds our processing and uses less material,” noted Konrad Kaiser, General Manager of Malibu. “This improves the overall sustainability of our product by reducing both environmental impact and manufacturing costs.”

Dean O’Connor, Head of Market Development and Technology at Linde Gases Division, said:  “Linde and Malibu have clearly demonstrated their leadership and foresight in helping the thin-film PV industry to reach a watershed moment. Green energy will only be truly green when the entire supply and manufacturing chain works together to minimise environmental impact.”

In 2008, Linde and Malibu established their Joint Development Programme for the development of advanced material technology to improve cell efficiency, throughput and yield.  F2 cleaning is the first of a number of material-based processes to emerge from their collaboration.

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
26 August 2021
In this webinar, JA Solar will present its product portfolio based on the latest technologies to improve your PV projects, ensuring maximum reliability and performance. During the webinar we will receive insight from JA Solar about its solar technology roadmap and how the manufacturer is providing customers with innovative solutions to suit their needs, while we will also analyse how to determine the best product solution for each solar project.
