Description

DESCRIPTION : Two independent positions are offered for the two topics of supercapacitors and solar cells. In both cases, a brand new plasma-enhanced chemical vapour deposition system (Aixtron BM Pro) will be used for the preparation of the graphene material.

Supercapacitors:
Electrodes will be developed by growth of graphene on 3D metal foams, using plasma-enhanced chemical vapour deposition. Their capacitance will be improved by using either conductive polymers or electrodeposited metal oxide nanoparticles. Supercapacitors cells will be fabricated and measured by means of a potenciostat-galvanostat system.

Solar cells:
2D graphene sheets will be grown by plasma-enhanced chemical vapour deposition on metal foils or blocks, typically made of copper. The graphene will be transferred to test substrates using different techniques, and the electrical conductivity and defect density of the graphene sheet will be characterized. Finally, different material (Si-, GaAs- and ZnO-) based solar cells covered by graphene will be characterised.

When
From January 2016
Maximum available positions

Prerequisites
High level of written and spoken English. Previous experience in electrochemistry (for supercapacitors) and electrical characterization (for solar cells).
