Major Field of Science: | Engineering and Technology | Field Category: | Electrical Engineering - Electronic Engineering - Information Engineering | Λέξεις-κλειδιά: | Interfaces;Inverted organic solar cells;PEDOT:PSS buffer layers;Printed electronics;Processing additives;Solution based electronic materials | Ημερομηνία Έκδοσης: | Νοε-2013 | Πηγή: | Organic Electronics, 2013, vol. 14, no. 11, pp. 3123-3130 | Volume: | 14 | Issue: | 11 | Start page: | 3123 | End page: | 3130 | Περιοδικό: | Organic Electronics | Περίληψη: | Solution based inverted Organic Photovoltaic (OPVs) usually use Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) derivatives combined with pristine processing additives as hole selective contact on top of the hydrophobic conjugated polymer:fullerene active layer. In this study, PEDOT:PSS based hole selective contact is treated with two different boiling point additives, 2,5,8,11-tetramethyl-6-dodecyn-5,8-diol ethoxylate (Dynol) and Zonyl FS-300 fluorosurfactant (Zonyl). Although corresponding inverted OPVs using the above PEDOT:PSS:Additives show similar power conversion efficiency (PCE) values, the mechanisms of their implementation on inverted OPV operation are not identical. By understanding the synergistic effects of PEDOT:PSS processing additives on the hole selectivity of inverted OPVs we demonstrate a novel combination of PEDOT:PSS additives mixture as an effective route to further increase the hole selectivity, reliability andpower conversion efficiency of inverted OPVs. | URI: | https://hdl.handle.net/20.500.14279/9789 | ISSN: | 15661199 | DOI: | 10.1016/j.orgel.2013.07.024 | Rights: | © Elsevier | Type: | Article | Affiliation: | Cyprus University of Technology |
