Design and characterization of conjugated materials for energy conversion application

Période: January-Jully 2021

Today, a worldwide challenge is posed by the issues of energy and environment, due to the limited resources and the burning of fossil fuel. Also, substantial global energy (>60%) ends up in the environment as waste heat. Thermoelectric (TE) technology, which can directly convert waste heat to electricity, is rapidly getting hot.

Currently, the state-of-the-art TE materials are inorganic semiconductors based on metal alloys. However, their inherent limitations, such as difficult processing, high manufacturing cost, brittleness, and scarcity, significantly hinder their widespread use. Encouragingly, conjugated polymers are currently recognized as promising TE materials, as they are easy to process, light-weight, environment-friendly, flexible, abundant thus low cost, structurally tunable and suitable for large-area fabrication. However, started only from recent years, the research of organic TE materials is still at its beginning, with low performance and fragmental understanding hampering their commercialization. In this project we thus propose to investigate the role of different polymer structures on the TE properties, aiming to setting molecular-design guidelines for the next generation efficient TE materials. The project will cover different aspect of materials science such as characterization of thermal, electrical, optical and electrochemical properties, thin film morphology and possibly fabrication of the corresponding nano organic thermoelectric devices.

Your Profile:

  • Master level student (M2R or the last year engineering school) with background in materials chemistry or related fields (organic chemistry, physical chemistry, material science).
  • High self-motivation and hard-work attitude are appreciated.
  • Hands-on experience in solution processing/characterization of conjugated materials and knowledge about semiconductor physics, organic solar cells or organic thermoelectrics are desirable but not mandatory.
