Organic Electronics and Photovoltaics

Organic electronics and photovoltaics investigates how carbon-based semiconducting materials — particularly conjugated polymers and small molecules — can absorb light, transport charge, and convert solar energy into electricity. Unlike conventional silicon devices, these materials can be dissolved into inks and deposited onto flexible substrates at low cost, making large-area, lightweight solar cells a practical possibility. Much of current research centers on engineering the nanoscale mixture of electron-donating and electron-accepting materials in bulk heterojunction devices, where the geometry of that blend directly controls how efficiently charges are generated and collected — a relationship that remains difficult to predict and control reproducibly. The rise of non-fullerene acceptors has pushed single-junction efficiencies past 19%, yet closing the gap with inorganic technologies while retaining the processing advantages of organic materials remains the central challenge driving the field forward.
