Idan Hod ereaned his B.Sc in Chemistry and Computer Science in Bar-Ilan University in 2002. In 2008 he graduated his M.Sc, cum laude (final grade 95), Chemistry Department, Bar-Ilan University, Israel, under the topic of Molecular crystal engineering, focusing on Predictions of solvents and additives effect on organic crystal morphology. Supervisor: Prof. Yitzhak Mastai. Currently he is studying for his  Ph.D under the supervision of Prof. Arie Zaban studiying  the field of photoelectrochemical solar cells. The research involves the development of advanced electrochemical characterization tools for the study of charge transfer and operation mechanisms of Quantum Dot Sensitized Solar Cells. The research is conducted using techniques such as electrochemical impedance spectroscopy, photo-voltage decay and charge extraction.
Using the knowledge gained so far, he currently designs new types of semiconductor absorbers which will be able to deliver both excellent charge separation and broader harvesting of the sun's spectrum, reaching to the NIR wavelengths.  

Research Topic: Development of Materials and Characterization Methods for Understanding the Mechanisms of Charge Transfer in Quantum Dot Sensitized Solar Cells.    

Objectives: Development of  new characterization methods which will enable us to obtain fundamental understandings on the operation mechanisms of Quantum Dots Sensitized Solar Cells (QDSSCs) with an emphasis on electrochemical techniques such as impedance spectroscopy, Voc decay, charge extraction, incident photon to current efficiency (IPCE) and photovoltage spectroscopy (PVS). The new insights gained by this research can help us improve the performance of our solar cell
