Major Field of Science: | Engineering and Technology | Field Category: | Mechanical Engineering;Materials Engineering | Λέξεις-κλειδιά: | Perovskite;Solar cells;Methylammonium lead | Ημερομηνία Έκδοσης: | 1-Ιαν-2016 | Πηγή: | Chemistry of Materials,2016, vol. 28, no. 8, pp. 2515-2518 | Volume: | 28 | Issue: | 8 | Start page: | 2515 | End page: | 2518 | Περιοδικό: | Chemistry of materials | Περίληψη: | A study was conducted to report a new, simple, hole transport material (HTM) composed of a central difluorinated phenyl ring, tetra-substituted with paramethoxydiarylamine groups (DFTAB). Devices fabricated using DFTAB demonstrated a stabilized PCE, had a higher energy absorption cutoff than devices utilizing the ubiquitous spiro-OMeTAD, and offered the potential to be used without the addition of ionic additives. The synthesis of DFTAB was carried out in a one pot reaction where 4,4'-dimethoxydiphenylamine was first deprotonated by NaH, followed by nucleophilic aromatic substitution of hexafluorobenzene with in situ generated amide sodium salt. The thermal properties were investigated by thermogravimetric analysis (TGA) . | ISSN: | 15205002 | DOI: | 10.1021/acs.chemmater.6b00858 | Rights: | © American Chemical Society | Type: | Article | Affiliation: | Cyprus University of Technology Imperial College London Swansea University |
