  • Patent number: 12150381
    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.

These advantages are achieved by forming a uniform layer of component B on the substrate, preparing a mixture of reagents that react with component B under predetermined conditions, and a reaction inhibitor that suppresses this reaction under these conditions; the prepared mixture is applied in stoichiometric amount or greater than stoichiometric on the layer of component B and the reaction inhibitor is removed from the mixture, ensuring activation of the chemical reaction between the mixture of reagents and component B to form films of perovskite-like material.
