Weight loss aids, teeth whiteners, hair-growth serums: When marketing personal improvement products, advertisements often highlight dramatically different before and after photos it seems intuitive consumers would be motivated by results, not the time and effort. Our findings suggest a simple approach to improve the stability of OPVs that utilize PEDOT:PSS as the HTL. High quality example sentences with see a marked improvement in context from reliable sources - Ludwig is the linguistic search engine that helps you to. Marketing Marked Improvement: Credibility and the Promise of Change. Moreover, the SAMs improved the interfacial electrical properties between the ITO and PEDOT:PSS layers, which maintained the PCE of the device. However, the PCE of the SAM-modified device was reduced by only 30% over the same period, and only to 48% after 98 days. Beginning with 3 stages of surface preparation by hand, followed by 2 stages of machine polishing, finishing with a UV filter sealant guaranteed for 12 months. The PCE of the pristine OPV diminished to zero at 49 days post-fabrication under ambient conditions. I offer a fully mobile service restoring deteriorated headlights back to factory like condition. By inserting a self-assembled monolayer (SAM) with carboxylic acid functional groups at the interface between the ITO and PEDOT:PSS layers, such diffusion could be significantly suppressed. Such behavior was responsible for the deterioration of the device. X-ray photoelectron spectroscopy depth profiles suggested that the acidic PEDOT:PSS etched the indium from the indium tin oxide (ITO) electrode, which resulted in indium diffusion into and chemical interaction with the active layer. We investigated the effect of self-assembled monolayers (SAMs) on the degradation of electrical properties caused by the diffusion of indium through the matrix commonly used in OPV devices. This work describes a simple process to improve the stability of small molecule organic photovoltaics (OPVs) that use poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as the hole transport layer (HTL), without reducing the power conversion efficiency (PCE).
