Manufacturing electronic components by thin-film deposition techniques on flexible substrates has challenged the engineers in various technical domains for quite some time now. Both sheet-to-sheet (S2S) and roll-to-roll (R2R) production technologies are being used, but the latter offer clear advantages in terms of throughput and cost of ownership.
The tremendous progress made during the recent years in R2R production equipment has led already to significant growth in the market of several flexible electronic components. More simple devices like sensors can be “printed” already on plastic foils at sufficiently low prices, but printing and coating the functional layers of more complex devices like organic photovoltaics (OPV), flexible perovskite and CIGS solar cells, thin-film batteries, flexible displays or flexible ICs require advanced equipment.
This presentation addresses novel R2R production concepts suitable for the manufacturing of printed electronics at high yields and low cost of ownership. New sheet-to-sheet (S2S) manufacturing concepts are also addressed.
Such production tools have been designed, built and installed at various customers. For example, a world efficiency record of perovskite solar cells has been achieved on one of these dedicated R2R pilot lines. Another R2R machines has been used for more than two and a half years for pilot production of OLED lighting modules for a medical application. Yet another complex production tool is being currently built to deposit CIGS stacks on flexible stainless steel webs of 1-meter wide. Yet another example concerns an R2R production system that deposits atomic layer at atmospheric pressure and very high speed.
