Abstract: Triazabicylodecene can effectively n-dope a variety of organic semiconductors, including PCBM, thus increasing in-plane conductivities. We synthesized a series of TBD-based n-dopants via an N-alkylation reaction and studied the effect of various alkyl chains on the physical and device properties of the dopants. Combining two TBD moieties on a long alky chain gave a solid dopant, 2TBD-C10, with high thermal stability above 250° C. PCBM films doped by 2TBD-C10 were the most tolerant to thermal annealing and reached in-plane conductivities of 6.5×10−2 S/cm. Furthermore, incorporating 2TBD-C10 doped PCBM as the electron transport layer (ETL) in methylammonium lead triiodide (MAPbI3) based photovoltaics led to a 23% increase in performance, from 11.8% to 14.5% PCE.

Abstract: Narrow bandgap n-type small molecules are attracting attention in the near-infrared organic optoelectronics field, due to their easy tunable energy band with a molecular design flexibility. However, only a few reports demonstrate narrow bandgap non-fullerene acceptors (NFAs) that perform well in organic solar cells (OSCs), and the corresponding benefits of NFA photodiodes have not been well investigated in organic photodetectors (OPDs). Here, the ultra-narrow bandgap NFAs CO1-4F, CO1-4Cl and o-IO1 were designed and synthesized for the achieved efficient near-infrared organic photodiodes such as solar cells and photodetectors. Designing an asymmetrical CO1-4F by introducing two different π-bridges including alkylthienyl and alkoxythienyl units ultimately provides an asymmetric A-D′-D-D″-A molecular configuration. This enables a delicate modulation in energy band structure as well as maintains an intense intramolecular charge transfer characteristic of the excited state.

Abstract: The present disclosure describes additives that attenuate a specific transport channel in ambipolar semiconductors to achieve unipolar characteristics. Carrier selective traps are included in the ambipolar semiconductors and are chosen on the basis of energetic preferences for holes or electrons and the relative positions of the molecular orbital energies of host polymer and the dopants. In one embodiment, a composition of matter useful as a current transport region in an organic semiconductor device comprises a semiconducting polymer; and means for accepting holes (e.g., a hole trapping compound) injected into the current transport region so as to impede conduction of the holes in the semiconducting polymer. This simple solution-processable method can improve the on and off current ratios (ION/IOFF) of OFETs by up to three orders of magnitude. Moreover, the treatment yields tailored blends that can be used to fabricate complementary inverters with excellent gain and low-power characteristics.
