- Recycling of spin-triplet excitons in organic photovoltaics
A study in Nature reveals that triplet excitons in organic photovoltaics (OPVs) can redissociate into free carriers via the charge-transfer state, reducing energy losses and enhancing efficiency. This process is facilitated by molecular design strategies that manipulate singlet–triplet energetics through exciton delocalization.
