Singulus To Outline Key Steps For CIGS Solar Panel Production

The firm is also looking into large-scale implementable production processes for CIGS solar cell development
Production capacities for CIS/CIGS based cells is anticipated to rise in the coming years.

Based on the CIGS processes, Singulus Technologies (Singulus) can provide customers with its extensive know-how to reduce production costs. The firm also works with its customers to increase cell performance and enhance cell output.

For the development of CIGS solar cells with a substrate size of 300 x 300 mm, Singulus is now offering a modular cluster type tool, the CISARIS. With this machine, innovative and large-scale implementable production processes for CIGS solar cells can be developed targeting new process combinations. Many research and development areas demand such cost-efficient development tools.

CISARIS Rapid Thermal Processing

The company's CISARIS rapid thermal processing oven is designed for the CIGSSe absorber formation on large area glass substrates. The process can safely handle the thermal processing of large glass substrates of over 1 square metre at temperatures up to 600 °C under a toxic and corrosive gas atmosphere.

High heating and cooling rates, combined with an excellent temperature and gas homogeneity during all process stages are the key factors which allow the formation of an optimal CIGSSe absorber required for the production of high efficiency solar modules.

CISARIS consists of a handling station, a vacuum tight process section, and a return conveyor and is optimised for the mass production of CIS solar modules., CISARIS provides a production capacity of over 25 MWp per year

Sputtering Systems

Singulus is also offering new processing systems for vacuum coating CIGS thin-film solar cells. The systems respond to the demand in the photovoltaic industry for development and production tools that enhance the efficiency of thin-film solar cells, while cutting production costs.

For PV technology, Singulus develops and manufactures coating systems which can apply special layers and layer systems on different materials. Inline sputter systems are significant in today’s thin-film solar cell production.

New Generation of Wet Process Equipment for Economic Processing of CdS/Alternative Buffer Layer for CIGS Solar Cells

Singulus has also made a promising new development to the efficient wet-chemical coating of thin-film solar modules made of copper-indium-gallium-diselenide (CIGS) on glass: the second generation of the TENUIS production which has a modular cluster build enables both significant savings in terms of required floor space and the simultaneous one-side coating of two substrates.

Singulus offers wet processing systems from R&D over pilot use to full production range 60, 120, 180 and more MW.

Due to new and unique concepts in terms of dosing and temperature control, Singulus` developers were successful in reducing the process time by up to 20 percent, which has a positive effect and a considerably higher output in production.

Inline Wet Process Equipment, Etching, Cleaning & Single Side Coating for Thin-Film Solar Cells

The modular design of the Singulus inline wet process equipment VITRUM II allows the easy integration of different process steps according to the requirements of CIGS, a-Si or CdTe technology (etching, rear side and substrate edge etching, cleaning, and single side coating).

The design of the VITRUM II features similar piping for all liquid circuits and generously dimensioned installation compartments for optimised maintenance work.

The second generation VITRUM enables homogeneous, reliable and reproducible etching. It features further advantages in comparison to a dipping bath, such as a higher etch length and concentration, a higher process speed of up to 5 m/min, and minimized carryover.

The design of the VITRUM GEN 2 improves the accessibility for optimized maintenance work in a large installation cabinet. Piping is similar for all liquid circuits. It offers a high cycle rate and is also easy to integrate into existing production lines.

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.
