Progress in Upscaling Organic Photovoltaic Devices
TL;DR: In this paper, the authors focus on four important challenges that OPV technology has to face to achieve a reliable lab-to-fab transfer, namely: i) the upscaling of indium-tin-oxide (ITO)based single cells and the interconnection of single cells into large area modules; ii) the development of alternatives to vacuum processing; iii) the developing of alternative to ITO-based substrates; and iv) strategies for improving the lifetime of large area OPV devices.
