Press release | Innovation for industry | Photovoltaic solar power
CARBON reiterates its initial choice of the
5th generation technology called TOPCon (Tunnel oxide passivated contact), a new generation of innovative but globally-endorsed cells, which is set to become the mainstream on the solar market in the coming years. Thanks to specific innovations, the company intends to further improve this technology performance on an industrial scale.
As previously announced, and upon the commissioning of its giga-factory will be done, CARBON will also commit to an
improvement of its cell technology called TBC (TOPCon back-contact) which presents tremendous advantages in terms of resource consumption but also yield and aesthetics.
To pave the way for the future, CARBON is already considering the industrial development of the
6th generation of so-called « tandem » solar cells, which combine two semiconductors enabling the capture of a larger part of the solar spectrum. CARBON, supported by its R&D partners, is examining the tandem technology known as silicon-perovskite with 2 terminals to sustain investments on the 5th generation and to seek better yields (beyond 30%). Work also focuses on the stabilization of perovskites. Additionnally, CARBON is exploring alternative tandem technologies to cover multiple technological options by 2030.
Outside the cell which is the core of value chain, CARBON works with its partners on
innovations on other steps of the process and components of its products in order to guarantee the ecodesign of its photovoltaics modules and to always remain at the vanguard of incremental and disruptive innovation. This applies for example to the epitaxial growth of silicon wafers, the evolution or even the disappearance of the frame, the reduction of the thickness or even the replacement of solar glass, etc.
CARBON relies on a
European network of innovative research centers, with the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) at the Institut national de l'énergie solaire (INES) in France, as well as the International Solar Center (ISC) Konstanz in Germany. Through the European research projects of its partners, CARBON also has access to specialized expertise in Switzerland, Spain and Belgium, among others.
Together with these strategic partners in research, development and innovation around its technological roadmap, CARBON intends to fully engage in European cooperation and target
a technological optimum for its future photovoltaics products, through an ambition that lives by these 5 words: competitive, reliable, sustainable, recyclable, efficient. This is about achieving the best performances while ensuring the lowest carbon footprint of the market and reducing the consumption of critical resources.
CARBON keeps a steady watch on future technological developments. As a reminder,
CARBON will devote at least 3% of its future turnover, i.e. several tens of millions of euros per year,
to R&D, which will help consolidate a leading European ecosystem regarding innovation on solar PV.
« Through these partnerships, CARBON intends to deploy its technological roadmap and positioned itself at the heart of the European ecosystem in terms of innovation on photovoltaics. Our goal: to be at the vanguard of technology and further strengthen the links between industry and research. CEA at the INES in France and ISC Konstanz in Germany are top-tier partners that we are proud to have by our side. »
« CEA has been conducting research in the field of photovoltaics on the INES campus for almost 20 years now. Since the origin, we are supporting this strategic sector, with our technological research and innovation strengths and our French research partners, The project of CARBON fits perfectly with this ambition. We are excited to contribute with our expertise on silicon and perovskite on silicon photovoltaic technologies to this industrial initiative. »
« Since our foundation of ISC Konstanz in 2005 we have been working on bifacial n-type technologies - more than 15 years before mainstream. Now, as the PV market is entering bifacial n-type era, we are well prepared to assist companies with ramping up GW solar cell and module production. With CARBON we have identified the right partner to set up the first vertical integrated GW PV production in EU. In addition, the experience of ISC Konstanz on the state-of-art crystalline silicon cell technology will help paving the way for tandem technologies in future. »
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
