Organic Electronics and Photovoltaics

Organic electronics and photovoltaics investigates semiconducting carbon-based materials — particularly conjugated polymers and small molecules — as the active layers in devices that convert light to electricity or control electronic signals. Unlike conventional silicon-based technology, these materials can be deposited from solution onto flexible substrates at low cost, making them attractive for large-area, lightweight, and wearable energy applications. Much of the current research centers on understanding how the nanoscale arrangement of donor and acceptor materials in bulk heterojunction architectures governs charge generation and transport, with non-fullerene acceptors having recently pushed power conversion efficiencies past thresholds once thought unreachable for organic systems. Key open questions involve precisely controlling thin-film morphology during processing and closing the remaining gap between laboratory-cell efficiency and the long-term stability required for commercial deployment.
