Project description
A fluid chemistry approach to organising microstructures in organic solar cells
Flexible, lightweight organic solar cells offer a low-cost alternative to traditional heavy solar panels, making them perfect for seamless integration into everyday surfaces. However, when these cells are manufactured from liquid solutions, the internal molecules aggregate randomly, creating chaotic structures that hinder electricity and undermine cell efficiency. Supported by the Marie Skłodowska-Curie Actions programme, the CoMoMi project will introduce tiny, controlled water-channel networks (microfluidics) to guide how these molecules self-assemble. Finely tuning liquid flow and concentration will allow researchers to seamlessly align the molecules into highly ordered microscopic active layer structures, thereby paving the way for predictable, mass-produced organic solar panels.
Objective
Solar energy is one of the most promising solutions for a sustainable future. Organic photovoltaics (OPVs) are particularly promising due to their lightweight, flexible, and solution-processable nature, which allows low-cost and large-area fabrication. However, device performance is strongly dependent on the nanoscale organization of the active materials. Conventional solution-processed films often exhibit uncontrolled aggregation and morphological variability, which hinder charge transport, increase energy losses, reduce reproducibility, and lower overall efficiency.
CoMoMi introduces the first systematic use of microfluidic flow chemistry to direct supramolecular self-assembly in OPVs. Microfluidics enables precise control over flow, concentration gradients, and mixing profiles at the microscale, allowing the formation of highly ordered, reproducible active-layer structures. By tuning flow parameters, including channel geometry, flow rate, and solution composition, the project will establish design rules to control molecular arrangements
and guide assembly pathways.
In situ characterization will monitor assembly dynamics in real time, linking molecular organization to device performance. Highly ordered microstructures are expected to enhance charge transport, reduce recombination losses, and improve power conversion efficiency, providing a reproducible pathway toward reliable OPVs. Beyond device optimization, CoMoMi will provide fundamental insights into how flow-directed assembly can control supramolecular structures, with potential implications for other solution-processed organic materials.
Overall, the project establishes a reproducible, tunable strategy for directing molecular organization, bridging fundamental understanding with practical device design. By linking precise molecular assembly to enhanced efficiency, CoMoMi paves the way toward next-generation high-performance, reproducible organic solar cells.
