Smit Ovens Makes Headway In CIGS "In-line" Production

The company has sold a total of ten roll to roll and sheet to sheet systems
Smit Ovens has successfully installed 10 in line production systems at five CIGS customer plants.
The systems cover selenium deposition, and/or crystallisation/annealing systems for pilot and or mass production, and development of thin-film CIGS cells that are produced using the two step CIGS manufacturing process. Both roll to roll and sheet to sheet applications are served.

“Thermal processes are a key way to achieve competitiveness in this growing market. We’re already seeing cell efficiencies of 15 percent," says Wiro Zijlmans, CEO, Smit Ovens.
Smit Ovens says its In Line Production System design are proven to be more cost effective due to doubled output compared to existing batch and in line solutions. What's more, the systems demonstrate high flexibility and repeatability in production that offers improved layer quality, high uptime and productivity.
Some systems are equipped with active selenium reactors which are linked to the crystallisation/anneal reactor. The balance of the systems installed are configured for annealing of glass and flexible substrates. Control of the selenium pressure at different process steps is realised, offering overall process stability. For instance, output performance is less dependent on precursor parameters as the active selenium process is correcting for differences in pre-deposited selenium layer thicknesses.
“This milestone underscores the strong relationship we have with our customers, who aim to be leading players in the global CIGS cell market," adds Zijlmans.
“As a machine builder, Smit Ovens has extensive experience in high-precision thermal solutions for the solar energy industry and we are eager to apply this know-how to new market areas such as CIGS. The Solliance Institute, which uses our R&D / Pilot System, is a highly valuable technology partner with a vast knowledge of CIGS materials, processes and requirements. The system at Solliance is available for Smit Ovens customers to use for verification and process development," concludes Zijlmans.
The company is showcasing its products at the 27th PVSEC in Frankfurt, Germany, between September 25th and 28th, 2012.


AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
