99 Prof. Zaban Arie President of BIU Department of Chemistry Member of BINA ex-Director of BINA Energy Center Research Areas • Solar energy • Dye Sensitized Solar Cells (DSSC) • Nanoporous wide band-gap semiconductor electrodes, single material and core-shell systems • Nanosize wide band-gap semiconductors with controlled properties via surface control • Low cost spectral splitting for multibandgap photovoltaics • Interdigitated organic/inorganic nanosize layers towards the development of low cost “plastic” solar cells and smart polymers Abstract The Cahen-Zaban group studies (opto) electronic materials, esp. for Photovoltaics. A major tool is combinatorial material science to answer renewable energy’s need for new materials, i.e., to explore compounds with unique characteristics with current focus on halide perovskites and charge-selective metal oxides. Further interests are in Biomolecules, esp. proteins as electronic materials for future bioelectronics.

On the fibers side, the group focuses on sensor applications: the use of optical fibers for the mapping of quantities of interest such as temperature, strain, and various chemicals. The group is pioneering a new sensor concept based on the combination of light and sound waves, which supports measurements outside the fiber boundaries where light cannot reach. On the devices side, the group specializes in photonic integrated circuits in silicon and glass, for data communication and sensing purposes. Examples include multiplexers for dense wavelength division communication, and narrowband radio-frequency filters. Here too, the group relies on interactions between light and sound waves to achieve performance that is unattainable using light alone.
