The new record 7.4% has successfully achieved for bulk heterojunction polymer: fullerene solar cells in an inverted single device stack, fully printed on a flexible substrate by R2R printing techniques based on slot die coating and inkjet printing for the various layers and electrodes involved. This new result confirms the world-leading technology of OET in large-area printing technology and processing of fully printed single junction OPVs onto flexible substrates. OET seeks to achieve 9% efficiency for large-scale OPV modules by 2021.
Based on the support of the running H2020 projects for a robust and digital nano-manufacturing of flexible large-area OPVs with tailored performance and high production yield, OET will widespread the implementation of OPVs in existing and new consumer products from Energy, Lighting, Displays and Surfaces, Electronic Circuits, all (Bio) Sensors, Wearables, ICT, IoT, etc. Customized fully printed OPV panels up 1 meter in length in a range color pallet like grey, blue, green, red, brown and shapes with a focus on client-specific requirements will be available on market in September 2018 at appealing prices.
OET, founded in 2012 and located in Thessaloniki, Greece, is among the key players in the field of organic photovoltaics. In addition, OET is a world leader in large-area production of fully printed OPVs with quality control. Digital closed-loop manufacturing of OPV panels and devices by scalable cost-efficient production processes such as R2R makes OET to stand out from its competitors.
