Current Funded Research Projects
Start: 19-10-2020 / End: 18-10-2023
This project will develop crystalline materials comprising well-defined nano-objects arranged on a regular lattice. These nano-objects will be either two-dimensional (ultrathin layers within the material), one-dimensional (linear structures within the material), or zero-dimensional (quantum dots within the material), with unusual electronic properties in all cases. These bulk materials, which are straightforward to process, will retain low-dimensional characteristics. These unusual characteristics will be used to boost the efficiency of energy devices. In particular, this project will investigate their use for thermoelectrics (conversion of waste heat into electricity), and photovoltaics, delivering in both cases new materials for improved energy devices.
Start: 01-04-2021 / End: 30-09-2023
This project will develop graphene-based organic light-emitting diodes. It is a Knowledge Transfer Partnership (KTP) between Paragraf Ltd. and QMUL. The KTP scheme helps businesses in the UK to innovate and grow by linking them with an academic or research organisation and a graduate researcher.
Start: 01-08-2020 / End: 31-07-2022
The KiriTEG project will develop flexible, miniaturised TEGs allowing the design of non-rigid thermoelectric energy harvester devices. This will be achieved by development of innovative semiconductor materials, materials deposition techniques and production processes to allow the commercial scaling of the project deliverables. This project utilises the skills of 'kirigami' (variant of origami that includes cutting as well as folding) to produce a new generation of low cost, highly flexible devices. These energy harvesting devices will operate between -40C and +120 C, which covers the vast majority of low grade harvesting applications.
Previous Funded Research Projects
Start: 01-10-2017 / End: 31-03-2021
Organic thermoelectric materials are in the early stages of development, and the excitement surrounding them lies in their low cost, solution processability (they can be printed) and their mechanical flexibility. In short, they could revolutionise thermoelectric power generation. In this project, an OTEG will be fabricated on paper by a novel printing process. It is a cheap, scalable process that is much-needed for OTEGs to become reality. Furthermore, this project follows the conviction that a fundamental understanding of OTEG device physics will accelerate the development of improved thermoelectric materials
Start: 11-03-2019 / End: 10-03-2021
HYPERTHERM will investigate new thermoelectric materials, specifically hybrid organic-inorganic perovskites, which are solution processable (printable), abundant and low cost. These materials are well-known in their undoped form in solar cells, and there are good indications that their superb electrical and thermal properties are well-suited to thermoelectric applications. However, to become good thermoelectric materials, they must be electrically doped to increase their conductivity. The principle scientific aim of this proposal is therefore to learn how to control doping in these exciting materials to boost their thermoelectric performance.

Organic Thermoelectrics in Multiple Structural and Transport Regimes.
Start: 01-01-2019 / End: 30-09-2020
Indium is expensive and is on the EU Critical Materials List. This project is to explore replacing Indium Tin Oxide (ITO) with next-generation graphene provided by the industrial partner Paragraf.
Start: 01-03-2017 / End: 31-08-2019
The purpose of this project is to develop a deep understanding of the role selfassembly in tuning thermoelectric properties of organic materials. Organic thermoelectric materials are heavily doped organic semiconductors. Despite their propensity for self-assembly into a range of intriguing morphologies, this mechanism has not been fully investigated and developed in the context of thermoelectrics.
Start: 15-03-2018 / End: 14-03-2019
High-resolution mapping of chemical activity of cells on surfaces is important for the understanding biological processes. We are aiming to develop the first flexible and biocompatible electrochemical imaging chip for in-vivo imaging of cell activity. The groundwork for this will be laid by this PhD project by developing novel organic semiconductor coatings suitable for high-resolution photocurrent imaging and measurement of cell-signalling processes such as cell impedance, cell surface charges, release of metabolites and neurotransmitters.
Other Research Projects
Flexible organic semiconductor-based chips can be used as light-addressable electrochemical sensors. This project will develop such chips.
Hybrid organic-inorganic perovskites have great promise as thermoelectric materials due to their exceptionally low thermal conductivities and high charge mobilities. This project will focus on characterising a range of these materials prepared by vapour deposition or from solution.
