Device Model Linking Singlet and Triplet Spin-State Properties to Organic Photovoltaic Device Characteristics
Jun Du, Liming Liu, Jun Yan
This work proposes an exciton-kinetics coupled drift-diffusion (EKDD) model that bridges device-level charge transport with singlet and triplet excited-state kinetics. State popula…
