Abstract: Organic photovoltaics (OPVs) is a promising renewable technology because of its low energy for production and the use of abundant materials. The performance of OPVs has experienced an unprecedent rise partly due to the development of the so-called non-fullerene acceptors (NFAs). This thesis tackles three relevant issues for the upscaling of NFA-based OPVs. First, the addition of NFAs in the photoactive layer is theoretically investigated as an efficient strategy to tune the device aesthetics. Second, a high-throughput combinatorial platform based on controlled gradients (1D/2D) in the parameters of interest is developed, enabling an efficient screening and optimisation of devices. Finally, mm2-size single-cells are further upscaled to cm2-scale flexible and semitransparent modules by two relevant industrially-compatible techniques such as slot-die coating and laser-patterning.
