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.
“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,” said François Barreau, marketing manager of Armor Sustainable Energies division (ASE). “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.”
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.
