Hybrids and quantum dots for thermoelectric applications


Project Description

The most efficient energy-harvesting devices today rely on highly pure and crystalline materials; but this mitigates against their ubiquitous deployment. Next-generation energy harvesting devices will require active materials that enable large-scale manufacturing and a facile integration of multifunctional lightweight devices.Solution-processed semiconductors have received a great deal of attention during the last decades as a promising class of materials to address this challenge. They offer ease of processing and compatibility with existing large-scale manufacturing processes. Hybrid perovskites and Colloidal quantum dots (CQDs) are a family with significant potential as the semiconducting building blocks of optoelectronic devices. This work involves the exploration of new hybrid halide perovskites and CQDs and their characterization for low temperature thermoelectric applications.​

About the

Derya Baran

Assistant Professor, Material Science and Engineering

Derya Baran

​Professor Baran's research interests lie in the area of solution processable organic/hybrid soft materials for electronic devices. Such soft semiconductor materials possess a viable platform for printed, large area, stretchable and wearable electronics that can be used as solar cells, smart windows, OFETs, thermoelectrics, sensors and bio-electronics.

​Professor Baran is particularly interested in interface engineering for organic/hybrid solar cells, transparent solar cells for building integrated photovoltaics and stability/degradation studies for long lifetime organic solar cells. She has led projects on i) conjugated polymers for electrochromic devices; ii) non-fullerene acceptors for organic solar cells; iii) multi-component and multi-layered solar cell devices; and iv) understanding the correlation between recombination and nano-morphology in solution processed solar cells.

Professor Baran aims to expand the applications of solution processable organic/hybrid semiconductors and to explore their limits in organic/hybrid thermoelectric devices and bio-electronics in the future.
