Fabrication of diodes rectifiers based on organic materials/liquid crystals for energy harvesting applications
The UDSMM laboratory (Dynamics and Structure of Molecular Materials Unit) is a research unit of the Littoral Côte d’Opale University (ULCO), focusing on the study and development of functional materials, particularly for energy-related applications. The SMAEO (Systèmes Moléculaires pour Applications Electroniques et électro-optiques) team at UDSMM is offering a final-year internship funded under the CPER MANIFEST program, concerning the development and optimization of a key component of the Rectenna (electromagnetic energy harvesting system), including an antenna and a rectifier diode. These diodes will be based on semiconductor organic materials (SCO). They can be produced on rigid or flexible substrates. The main challenges in their design are to reduce operating voltage and increase response frequency. These characteristics can be optimized by the choice of active material and diode architecture.
The internship will involve the development and characterization of diodes based on organic semiconductor materials, through :
- Development and optimization of organic material deposition conditions
- Study of the relationship between morphological structure and charge transport in OSCs
- Static and dynamic characterization of the components produced.
