New Materials and Process for High Performance Organic Solar Cells

New Materials and Process for High Performance Organic Solar Cells

Internship Description

Successful commercialisation of organic solar cells requires a combination of high performance, stability, and low cost processing.  We have an active research program to address each of these requirements.  High efficiency materials design requires optimal light absorption across the solar spectrum, effective charge separation and photocurrent generation.  Our synthetic strategies are focussed on new electron donor and acceptor combinations which can accomplish this process efficiently, and one of our projects involves organic synthesis of new conjugated aromatic semiconducting materials.  The second project involves the characterisation of these materials using optical and electrical methods, as well as fabricating solar cell devices. Our development of a new isoindigo polymer has demonstrated a record power conversion efficiency of over 9% in a device without a thermal treatment processing step and without the use of additives in the formulation.  Reductions in processing energy and time are essential for this technology to be competitive as an energy source, therefore eliminating thermal treatment is an important achievement.  ​​​
