The Sun can provide us with a virtually infinite amount of energy, and this is why solar cells represent one of the leading technologies for renewable energy harvesting. Among those, organic photovoltaics (OPVs) have the benefit of short energy payback times and high manufacturing speeds using large-scale roll-to-roll processing at ambient temperatures. However, they are not yet competitive on the market due to their insufficient stability and efficiency, but recent progress on non-fullerene acceptor materials has made it possible to overcome the 15% PCE mark in lab-scale devices. The aim of the project is to obtain a device with the highest possible efficiency using only scalable techniques.
