56 Prof. Cahen David Department of Chemistry BIU Faculty of Chemistry WIS Member of BINA Energy Center Research Areas • Alternative Energy: Photovoltaics (PV), esp. materials for high voltage, low-cost, stable PV • Combinatorial synthesis and characterization of optoelectronic materials • Semiconductor materials & device chemistry & physics • Biomolecular optoelectronics • Fundamentals of proteins as electronic materials 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.
