Donor-acceptor interface in blends of self-assembling and semi- conducting for opto-electronic applications

1 year Postdoctoral Fellow in conjugated at ICS.

A postdoctoral fellow is sought to work on an interdisciplinary project involving the control of crystallization of semi-conducting polymers, their structural characterization and their use in opto-electronic devices.

Project summary: Organic electronic materials have shown potential to elaborate thin, lightweight, flexible, and large-area electronic devices. The technology has progressed significantly over recent years, with polymeric electron donors now affording power conversion efficiencies above 10%. The drive for efficiency improvements and long-term stability involves various strategies, some of which are based on precise engineering of donor-acceptor interfaces. This research project focuses on an innovative physico-chemical method to control the crystallinity of the organic materials. It aims at elaborating hybrid materials by co- organization of self-assembling systems and semi-conducting polymers. To reveal the mechanism of nano-structuration, the obtained morphologies will be studied by various in situ methods: TEM (low dose electron diffraction), FTIR and UV-Vis absorption spectroscopies. Precise growth control of the hybrid materials will lead to nanostructured donor-acceptor materials to be tested in opto-electronic devices.

Required education and experience: Applicants should hold a Ph.D. in Polymer Science, or with a solid expertise in morphology control, structural characterization of conjugated materials or organic device elaboration and characterization. Team capability and good skills in English are required.

Applicants should have a maximum of two years of experience (salary: about 2500 Euros gross / month).

Starting date: end of 2015 – beginning of 2016.

Contact: To apply, please send a CV with a publications list and the contact of two references to: [email protected] [email protected].
