We focus on the design of new organic, oxide and hybrid materials for solar energy conversion. We work along two directions: organic photovoltaic (PV) solar cells and oxide-based photoelectrochemical (PEC) systems. The first type of devices transforms solar light directly into electricity whereas the second one converts solar light into clean and readily usable fuels such as H2 and O2 through water splitting.

To achieve our goals we need to control the various steps of the bottom-up process going from molecule synthesis and raw material to thin film deposition to device fabrication and testing. Therefore, we are equipped with a series of complementary facilities: a chemistry lab for the synthesis of materials (organic molecules, oxides, polymers), various equipments for thin film deposition (UHV chamber, spin-coater, ALD), characterization instruments (probe station, IPCE, solar simulators, AFM, STM, SEM, XRD, etc). These tools allow us to perform the following experimental actions:

     • Synthesis of small π-conjugated molecules (organic semiconductors)
     • Vacuum and wet deposition of organic thin films
     • Supramolecular 2D self-assembly and STM imaging
     • Growth of nanostructured oxides (TiO2, ZnO, Cu2O, WO3, etc)
     • Fabrication and testing of organic PV solar cells and oxide-based PEC systems

Our lab benefits from the financial support of Nanyang Technological University (Start-Up Grant) and the Singapore Ministry of Education (AcRF Tier2 MOE2014-T2-1-132). We also benefit from the support of the French Centre National de la Recherche Scientifique (CNRS) and Université Pierre et Marie Curie (UPMC) in Paris, France.
