Biography

Prof. Yi Hou is currently an Assistant Professor of the Chemical and Biomolecular Engineering, the National University of Singapore and the Head of the Perovskite-based Multijunction Solar Cell Group. Dr. Hou received his Ph.D. degree from the University of Erlangen-Nuremberg. Then he worked as a postdoctoral fellow at Electrical & Computer Engineering, University of Toronto, Postdoctoral. His research interests include Development and investigation of ultra-efficient solar energy conversion using perovskite-based tandem solar cell, with a strong focus on the development of wide-bandgap absorbers and interface materials, and design of nano-sized optical and electrical microstructures for accelerating the tandem production from lab to fab.

Abstract for Presentation

Emerging Perovskites-based Tandem Solar Cells: towards efficient, stable, and commercially viable photovoltaics 

 

The development of perovskite-based tandem  solar cells represents a promising strategy  to  enhance  the  performance  of  traditional  photovoltaics  beyond  the  singlejunction  Shockley-Queisser  limit.  This  talk  will  deliver  the  rationale  behind  widebandgap perovskite design for  the different tandems [1-3] , explain how the thin-filmbased  tandem  solar  cells  reached  high  efficiencies,  and  unveil  the  potential  of  this technology. The advances reported herein show that it is possible  –  and powerful  –  to marry the traditional PVs and perovskite technologies in tandems.
