Public Seminar of RPg Student:
Optoelectronic Devices Applications for Organometal Halide Perovskite

Speaker Mr. Ho Won TAM
Affiliation The University of Hong Kong
Date May 4, 2017 (Thursday)
Time 3:30 p.m.
Venue Rm 522, 5/F, Chong Yuet Ming Physics Building, HKU

Abstract
 

In recent development of solar cells, metal halide perovskite AMX3 (A = organic cation, M = metal cation, and X = halogen anion) solar cells stand out among others. These semiconductor materials have several desirable characteristics including low density of defects or impurities, long charge carrier diffusion length, effective collection of charges and simple fabrication process, therefore resulting in rapid development in terms of power conversion efficiency (PCE), raising from initially 3.8% to certified 22.1% according to NREL. This seminar will describe the perovskite morphologies, related synthesis techniques and discuss devices applications such as solar cells and light-emitting diodes. Lastly, the challenges and the future directions during my period of MPhil study will also be highlighted.

Anyone interested is welcome to attend.
