Hole Conductor Free Perovskite-based Solar Cells (eBook)

Lioz Etgar obtained his Ph.D. (2009) at the Technion–Israel Institute of Technology and completed post-doctoral research with Prof. Michael Grätzel (2009–2012) at EPFL, Switzerland. Since 2012, he has been a senior lecturer in the Institute of Chemistry at the Hebrew University. Etgar’s research group focuses on the development of innovative solar cells while designing and controlling the inorganic sensitizer structure and properties to improve the PV parameters.
