CEA-Liten announces fully inkjet manufactured flexible organic PV modules

Process results in a power conversion efficiency rate of 4%

16 Jul 2015 | Editor

Researchers from CEA-Liten, based at INES, France, have announced they have developed a flexible organic photovoltaic module manufactured entirely by inkjet printing processes that demonstrates power conversion efficiency above 4% for high value, custom-made, solar devices.

These results represent the culmination of four years of efforts primarily directed towards the development of printing platform with industrial printheads (up to 1024 nozzles), printing process (in ambient air atmosphere) and post-treatment of every layers as well as materials and multi-layer 3D structure optimization.

The process route has been optimised on INES technology platform devoted to organic PV. The printed modules with a size of 15x10 cm are constituted from eight individuals cells in the form of stripes interconnected in series are able to produce an electrical output of 0,41 W under 3,8 V. This represents a power conversion efficiency of 4.3% over the active area.

Inkjet printing process actually enables the direct patterning of each layer without any mask leading to an important freedom of design. This technological breakthrough enables the development of fully custom-made printed PV modules covering a wide variety of variables including: electrical characteristics, design, shape or colouration.

The organic/hybrid printed photovoltaic field is growing and is getting reaching the production scale where development of large area processes is needed. CEA-Liten believe this is a strategic technology for further development and integration with a range of mobile devices and the Iot (Internet of Things).
