Control of n-type inorganic morphology, chain orientation and crystallization of the donor polymers is of significance in hybrid solar cells. Here, we use slot-die printing combined with wet chemistry to fabricate controllable mesoporous TiO2 nanostructures in large scale. Subsequently, the mesoporous TiO2 films with different pore size are backfilled with P3HT and PffBT4T-2OD, respectively,...
Quantum dots (QDs) with near infrared emission are promising for use in photodetectors (PDs) for sensing and in photovoltaics (PVs) for solar energy conversion. High quality QDs are normally synthesized in solution and capped with organic ligands. To efficiently functionalize the QDs’ array for PD or PV devices, the ligand exchange treatments, in solution or on solids, to colloidal QDs are...
