The CELLO project (or Cost-Efficient Lighting devices based on Liquid processes and ionic Organometallic complexes) aims to develop thin film flexible and large area lighting sources based on light-emitting electrochemical cells (LEC). CELLO also aims to develop scalable and roll-to-roll (R2R) compatible wet deposition processes.
CELLO hopes that the final panels will provide a large area white light source that is:
- efficient (over 25 lm/W)
- stable (over 5000 hours)
- low cost (less than OLEDs)
The project consortium is shared by Siemens, OSRAM and five research institutes from Spain, Switzerland, Italy and Finland. CELLO will cost a total of 6.1 million Euro.
In December 2012 OSRAM said they already produced a large (15x14 cm) LEC prototypes on an R&D setup at Augsburg as part of CELLO.
