Organic Photovoltaics
Exploring new polymers and small molecules as photoactive layers in organic solar cells.
We investigate donor-acceptor systems and their interfaces to deepen the understanding of exciton dynamics, charge carrier generation, mobility and extraction in solar cells and solar batteries.
Key questions
- What chemical and photophysical processes drive degradation under light, heat, and in air?
- How can we disentangle overlapping excited-state absorption signals from various species?
- How do molecular packing and morphology affect carrier mobility and recombination?
Recent highlights
- Charge recombination in polythiophene: non-fullerene acceptor solar cells with IE offsets exceeding 1 eV Energy & Environmental Science (2026)
- Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro- and Microscopic Perspectives Advanced Energy Materials (2026)
