Dr Andreas Pusch

Engineering
Photovoltaic and Renewable Energy Engineering

Andreas obtained his Diplom in Physics from the Technical University Darmstadt. His thesis work was performed on complex networks under the supervision of Professor Markus Porto. In 2012, he obtained his PhD from Imperial College London in the group of Professor Ortwin Hess, working on self-induced transparency solitons and plasmonics. He continued at Imperial College for a number of years, mainly working on plasmonics, intermediate band solar cells and carrier dynamics in semiconductors.

Dr. Andreas Pusch is currently a research associate in the School of Photovoltaics and Renewable Energy Engineering, working with Associate Professor Ned Ekins-Daukes.

Andreas’ work focuses on the fundamental understanding of advanced concept solar cells and other power-generating optoelectronic devices. His particular interest is to find simple, semi-analytical models that describe the general behaviour of such devices and elucidate the proper material requirements.

He also works towards user-friendly models for the interpretation of ultrafast spectroscopy measurements.
