FWF - SCspatPED - Microscopic Inhomogeneities in Organic Solar Cells Caused by PEDOT:PSS

Project: Research project

Project Details


Organic semiconductors play an important role in modern technology. Especially in organic photovoltaics, devices still suffer from spatial variations, as they have detrimental effects on the local device physics and thus on the entire device in performance. One suspected source of origin therefore is the colloidal PEDOT:PSS electrode interlayer. This project investigates the very basic microscale diode physics in organic devices with a focus on the conditions of this PEDOT:PSS interlayer.This will allow forecasts of performance variations of devices, depending on the density of according inhomogeneities associated with the PEDOT:PSS interlayer. The expected new insights gained from this project will not only help understanding of the device behaviour of solar cells comprising PEDOT:PSS interlayers, but shall also allow conclusions to other colloidal systems in use and in future, like graphene or nanowires.
