| Prof Denis Fichou | Our present research aims at conceiving novel materials, either organic or inorganic in nature, in view of energy applications such as sunlight conversion and storage.
1. Organic and hybrid photovoltaic cells
We design and synthetize novel small organic molecules having an extended pi-electron system and use them either as active materials (p- or n-type semiconductors) or as interfacial layers in thin film solar cells. We recently developed series of molecules such as for example dipyrranylidenes and organo-cobalt complexes, that we used to fabricate efficient photovoltaic solar cells.
2. Oxide-based photoelectrochemical systems
We aim at converting efficiently sunlight into clean and readily usable fuels such as hydrogen or methane on a large scale. One of the most promising technologies consists in splitting water into hydrogen and oxygen through solar irradiation of semiconductor-based devices. We recently designed various efficient PEC systems based on either WO3, Cu2O, or BiVO4 among others, and used them under sunlight illumination to produce hydrogen.
3. Supramolecular self-assemblies on surfaces
The self-assembly of organic molecules on solid surfaces provides a versatile route towards functional 2D arrays in view of energy, catalytic and magnetic applications. Our group develops unique supramolecular architectures by controlling the size and shape of the molecular bricks. We then observe and manipulate the assemblies at the atomic/molecular scale by means of scanning tunneling microscopy (STM). |

He is interested in understanding and improving the structure and properties of these smart materials, and further exploring their signal/energy conversion and storage functional mechanisms including their potential device applications. As the program manager, he is leading a research program focusing on material-critical sensor and transducers at Institute of Materials Research and Engineering in A*STAR. Working together with his colleagues and students, he has designed and demonstrated a variety of material-critical sensors, actuators, and transducers on the basis of the functional mechanisms of the smart materials. Processing of functional thin films, thick films, multilayers, and micro/nano fabrication processes are often applied to produce miniaturized devices. |
