Missions

The postdoctoral researcher will work in the field of Engineering Sciences, and more specifically in the area of ​​high-efficiency photovoltaic devices (Gallium Arsenide GaAs and/or Silicon), their optoelectronic metrology, and their performance in wireless optical communications. The main objective is to develop and optimize a laser charging system to improve the flight time of drones used for emergency management (providing support and technical assistance to rescue teams deployed in various emergency situations). The charging system will also be adapted/modified for evaluation in the reception of optical data, to ensure the resilience of uplink communications with the drone. Contributions to the optical simulation of the system will also be welcome.
The candidate will contribute to the European project (Horizon Europe) HURRICANE (Holistic UGV-based Resilient and Real-time Intelligence for Crisis and Natural Emergency, project website: https://www.alphanov.com/en/collaborative-projects/hurricane-european-project). This project is based on a multidisciplinary European consortium whose objective is to increase the efficiency and safety of first aid operations during disaster situations through the use of advanced robotic technologies. By combining drones, autonomous ground vehicles, and intelligent communication systems, it aims to optimize risk management, reduce operational hazards, and boost the European robotics industry.

Activités

The postdoctoral researcher will be involved in the technological choices concerning the photovoltaic modules to be selected for the application, in their advanced laboratory-scale metrology (static and dynamic), and in predicting their performance using an optical simulation developed within the XLIM laboratory. More specifically, the candidate will actively participate in their integration onto the drones selected for the project by the national and international partners of the European consortium. They will maintain close contact with the teams of the regional partner ALPhANOV (Optics and Laser Technology Center) responsible for developing the laser source, and they will participate in experimental validation campaigns conducted both at laboratory scale and in representative environments, in collaboration with the partners. In this context, the candidate will be expected to regularly communicate his results (measurements and data analysis) to the partners and through scientific publications and national and international conferences.

Compétences

The candidate must hold a PhD in Physics or Engineering Sciences applied to the development of photovoltaic technologies and/or wireless communication systems, with significant experience in optoelectronics, photonics, and/or electronics. In particular, the candidate must be familiar with: - Standard techniques for characterizing optoelectronic components - Optical and electrical metrology of photovoltaic devices - Fundamentals of signal processing. A demonstrated ability to work independently, to think outside the box within Engineering Sciences, and excellent communication and scientific writing skills (in English) are just as important as academic qualifications. The successful candidate must demonstrate a genuine interest in collaborative work within a European consortium, exhibiting strong scientific maturity and a passion for fieldwork. Direct experience in photovoltaics and/or optical communications will be an asset.
