Nantes, France / Sunnyvale, Californy — The development of a scalable manufacturing process has been announced by Armor, a specialist in ink chemistry and printing technologies, and  Cambrios Technologies Corporation, leader in silver nanowire-based solutions for the transparent conductor markets. The new producton methodf allows Armor to mass produce organic photovoltaic (OPV) devices, in line with its sustainable development policy. Armor has designed flexible solar modules using Cambrios’ ClearOhm® silver nanowires as electrodes.

OPV technology is maturing. However, one of the hurdles in achieving high volume, appropriate costs and required performance is the traditional transparent conductor used in OPV devices, indium tin oxide (ITO). ITO is brittle, expensive and not scalable to very large volumes without huge capital investment.

According to  François Barreau, marketing manager of Armor Sustainable Energies division , “the implementation of transparent, flexible and highly conductive ITO-free electrodes is a high priority for Armor and a major step for the OPV industry. With the recent progress in developing a sustainable, high volume manufacturing process using ClearOhm electrodes, we are making OPV production an industrial reality. We will continue to develop such industrial alliances to support the commercial growth of the OPV market worldwide.”

“We are thrilled to have achieved such a milestone together with Armor,” said Rahul Gupta, senior director of business development at Cambrios. “After successfully gaining traction in the touch sensor market, ClearOhm material is now enabling new high volume applications. Our solution provides benefits that will allow Armor to create differentiated products and introduce a new generation of solar cells.”

Through their partnership, Armor and Cambrios have successfully achieved a cost effective, scalable roll to roll production process for transparent electrodes. The silver nanowire based electrodes are not only highly conductive and transparent but also enable solar cells that are flexible, foldable, formed into different shapes and even wrapped around a pillar or building.

Armor will exhibit at the Pollutec from December 2nd to 5th at Eurexpo Lyon / France in Hall 4 – Alley L – Booth 205.
