  • Offer Starting Date: 26/09/2022
  • Design, realization and use of an optical assembly using passive elements (lenses, mirrors, microscope objectives) and powered by a continuous laser, single or multimode, class 3 or 4. Handling of semiconductor, bulk or nanostructured samples. Acquisition of spatially resolved spectroscopic data by a hyperspectral imager over a wavelength range between visible and near infrared. Data analysis using the Generalized Planck's Law to extract the thermodynamic properties of the charge carriers.

    1. Perform extensive optical characterization of HCSC devices developed for the ICEMAN project. This task will require experimental acquisition, optical modeling and data analysis. The aim of these studies is to assess the performance of the device, and to provide guidance for the design and the improvement of the next batch of samples. 2. Develop further strategies to investigate and understand the dynamics of hot carriers. This task will be more precisely define with the post doc researcher, but could notably address bridging the gap between steady state and time resolved analysis ; or investigate the thermoelectric properties governing hot carriers transport (Seebeck effect).

    This post doc takes place in the framework of the ICEMAN ANR project (Improvement of photovoltaic Conversion Efficiency by acting on thermalization MecANisms) which gathers 5 labs (IPVF, C2N, LPCNO, IN2MP and FOTON) to investigate Hot Carriers Solar Cells (HCSC). Our team at IPVF has developed a strong expertise is the optical characterization of hot carriers with spectral + spatial resolution (hyperspectral) and spectral + temporal resolution (streak camera). Within the consortium, our contribution is therefore to characterize and understand the properties and dynamics of photogenerated hot carriers through photoluminescence. This work will be carried out within the team carriers, hot, consisting of two researchers of the laboratory (Daniel Suchet & Jean-François Guillemoles) and a PhD student.

    Eligibility criteria

    - Design, realization and use of simple optical assemblies - Acquisition, management and processing of data - Basic knowledge of semiconductor physics and optical spectroscopy - Prior knowledge of solar cell or hot carrier physics is not required.
