Postdoc on perovskite PV tandem architectures H/F

The proposed postdoctoral subject concerns different aspects in terms of material development, processes and advanced characterizations within a team composed of scientists, PhD students and technicians and in collaboration with different institutes:
- Material developments:
o the development of stable and processable high and low bandgap perovskite materials in tandem architecture.
o The interfacial materials used in a photovoltaic cell for the extraction of charges (electrons and holes) will have an important impact on the crystallisation of the thin perovskite layer and also on the electrical performances delivered by the complete device. Developments will have to take into account these aspects.
- Processes: different strategies for the deposition process could be envisaged (solvent or gas process). The elaboration of the tandem architecture maintaining the integrity of the underlayers will be the critical points to address.
- At the same time, different characterization methods, available in the laboratory or on the INES characterization platforms, will be used to qualify the materials (XRD, UVvisible absorption, ellipsometry, photoluminescence, SEM,…), the architectures (EQE,
photoluminescence, electroluminescence, STEM/EDX) as well as the electrical performance of the final devices (I-V, EQE). 

Global objective:

Chemical engineering and control of the crystallisation process of low and high bandgap perovskite material on large area for integration in tandem photovoltaic cell to reach 30 % power conversion efficiency.
