Publication number: 20220293866Abstract: 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.Type: ApplicationFiled: May 27, 2022Publication date: September 15, 2022Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, THE MITSUBISHI CHEMICAL CORPORATION, A JAPANESE CORPORATIONInventors: Julia Schneider, Michael L. Chabinyc, Hengbin Wang, Hidenori Nakayama, Kyle D. Clark, Javier Read de Alaniz

Publication number: 20150361274Abstract: A method for coating a metallic surface with an aqueous composition for pretreating before applying another coating or for treating said metallic surface. In addition to water, the composition contains: a) at least one hydrolyzable or at least partially hydrolyzed silane; b) at least one metal chelate; c) at least one organic film former, and; d) at least one long-chain alcohol that serves as a film forming aid. The unsoiled, scoured, cleaned and/or pretreated metallic surface is brought into contact with the aqueous composition so that a film forms on the metallic surface, which is subsequently dried, compacted in part or completely by film formation and, if necessary, additionally hardened. The dried and, if necessary, additionally hardened film has a layer thickness ranging from 0.01 to 10 ?m. The invention also relates to corresponding aqueous compositions.Type: ApplicationFiled: August 25, 2015Publication date: December 17, 2015Inventors: Heribert DOMES, Julia SCHNEIDER
