Undergraduate materials work on solvent treatment for organic photovoltaics.
An early collaboration on organic photovoltaics at UESTC, published as (Kong et al., 2019). We showed that a simple alcohol solvent treatment improves the efficiency of non-fullerene organic solar cells.
Well outside my current research area, but included for completeness.
