Dawei's paper on OPVs/OPDs is accepted in EES

Through integrating CsPbI₂Br PQDs into various polymer:non-fullerene organic optoelectronic systems, strong chemical interaction between the PQDs with the Nitrogen/Sulphur atoms of non-fullerene acceptors is revealed. This interation passivates defects of PQDs and improves the dielectric constant of photoactive layer, and resulting in a broader depletion region, which enhances carrier extraction and reduces charge recombination, leading to enhanced PCE from 18.8% to 20.2% in photovoltaics and D* from 1.1*10¹¹ to 6.5*10¹² Jones in photodetectors.
