Flisom, a Swiss company developing innovative technologies for manufacturing of flexible thin film CIGS solar modules (copper-indium-gallium-(di)selenide), has now received an additional investment of CHF 10 million following an earlier investment of CHF 42.5 million in 2013 for the pilot-production plant with an annual capacity of 15MW in Niederhasli-Zurich in Switzerland. During last years Flisom improved the design of roll-to-roll manufacturing machines for processing and scaled them up from 50 cm width to 1 meter width rolls an unprecedented scale of manufacturing capability for continuous processing of cost efficient, high performance monolithically interconnected flexible CIGS solar modules on plastic foil.
This fourth round of funding comes from Flisom’s existing strategic investor, the Tata group, a global enterprise headquartered in India . “We are very pleased with this further investment from the Tata group coming on the eve of the inauguration of Flisom’s 15 MW capacity pilot production plant, and we thank the Tata group and existing investors for their continued support”, said Dr. Ayodhya Nath Tiwari, Chairman of Flisom Company.
“We appreciate the systematic approach towards innovation and the continuous hard work of Flisom’s team in developing a unique manufacturing plant, while partnering with Empa, one of the world’s leading labs, with several efficiency-related records for flexible solar cells”, said Mr. K.R.S. Jamwal, Executive Director, Tata Industries. He further adds,“This investment marks Tata group’s interest in next-generation technology for the solar photovoltaic industry.”
“With the investment received in 2013, Flisom refurbished an old manufacturing building of 4500 square meter ground area in Niederhasli, in the outskirts of Zurich, to install all the needed machines for solar module manufacturing on 1 meter wide rolls. At the same time, Flisom continued technology development on 50 cm wide rolls at its Dübendorf plant, located on the campus of Empa”, says Flisom’s Chief Operating Officer, Dr. Sudheer Kumar.
The Chief Executive Officer of Flisom, Mr. Ulfert Rühle said,“After the successful installation of machines and other factory infrastructure in Niederhasli, the next step is to transfer the process know-how on these high-tech machines using specifically customized designs. Some of the machines are based on many years of development by experts, innovative proprietary designs and complex engineering making Flisom’s machines unique for achieving cost and performance efficiency targets for a breakthrough manufacturing”.
“The 15MW plant will serve as a proven blueprint for establishing larger production plants having a production capacity greater than 100 MW as well as low capital and operating expenditures. Flisom has been working steadily towards lowering the costs of manufacturing of flexible solar modules”, added CEO Rühle. Flisom’s high performance, lightweight, and robust products and systems could lower the price of solar electricity thanks to low material usage, economic production technology, and reduced storage, transportation and installation costs. Markets addressable by Flisom’s flexible solar module manufacturing technology include utility scale solar farms, building integrated photovoltaics (BIPV), building applied photovoltaics (BAPV), transportation and portable power.
The key is high performance and low cost roll-to-roll manufacturing
Ayodhya N. Tiwari, founder of the ETHZ spin-off company Flisom and the Head of the Laboratory for Thin Films and Photovoltaics, Empa-Swiss Federal Laboratories for Material Science and Technologies, believes that the high efficiency flexible and lightweight CIGS thin film solar cells have great potential to provide low cost installed solar systems, bringing many beneficial features together in a very unique manner. In addition to the economic benefits, CIGS thin film modules, known for faster energy payback than the mainstream Si wafer technology, will significantly contribute to CO2 reduction. Future norms and regulations are expected to enforce application of carbon footprint reducing technologies. Therefore, the broad range of applications of flexible lightweight CIGS modules, especially in buildings, will open up untapped markets worth several billion Euros while advantageously reducing carbon footprint. This goal is achievable with highly efficient, long term performance stable, low cost solar modules produced in a low capex production plant.
Empa and Flisom have been cooperating for a number of years to develop a unique industrial-scale production platform for CIGS solar modules. “Scale-up for large-area solar modules and adapting these complex innovative processes for industrial manufacturability is quite a challenge and requires close collaboration between research labs and industrial partners for transferring research excellence to industrial usability”, says Pierangelo Groening, head of the Department of Advanced Materials and Surfaces and member of Empa’s Board of Directors. ”For industrial partners such as Flisom, we provide support on different topics to enable industrial development of novel and innovative concepts, which often require sophisticated analytical tools and skilled experts.” Empa CEO Gian-Luca Bona adds: ”We are pleased that Empa’s innovations in the field of renewable energy, especially in photovoltaics, are being transferred to industry for the benefits of a more sustainable society with a growing energy demand. This example perfectly illustrates Empa’s role as a bridge between research and practical applications.”
“Flisom is thankful to Empa for very valuable and sustained R&D support over several years. Flisom also thanks Swiss federal and European funding agencies for their continuous support. Besides the technological progress, the number of employees during the last two years have gone up to more than 55 now, and of course more employment opportunities for technically skilled persons are open for the production plant in Niederhasli”, said Flisom CEO Ulfert Rühle.
