About the Authors
Dr. Bram Hoex
is director 
and group leader in SERIS’ 
Silicon PV Cluster. He 
holds a Ph.D. degree in 
a p p l i e d p h y s i c s f r o m 
Eindhoven University of 
Technology and has extensive experience 
in the area of processing and advanced 
characterization of high-efficiency silicon 
wafer solar cells. In 2008 Bram won the 
SolarWorld Junior Einstein Award and the 
Leverhulme Technology Transfer Award 
for his work in the area of high-efficiency 
silicon wafer solar cells.
Prof. Armin Aberle 
is the 
C E O o f SE R I S at th e 
National University of 
S i n g ap o re ( N U S ) . H i s 
research focuses on reducing 
the cost of ele ctr ic ity 
generated with silicon solar cells (wafers and 
thin films). He is an editor of several journals 
and established the Silicon PV Department 
at ISFH in Germany in the 1990s. He then 
worked for 10 years in Australia, as a 
professor for photovoltaics at the University 
of New South Wales (UNSW). In 2008 
Armin joined NUS to establish SERIS, with a 
particular responsibility for the creation of a 
Silicon PV Department.
Dr. Rolf Stangl
is a senior 
research scientist at SERIS. 
He is a project leader for 
hybrid heterojunction solar 
cells and a competence 
team leader for electrical 
characterization/simulation. He was 
awarded his Ph.D. degree in organic solar 
cells for work conducted at Fraunhofer ISE 
in Freiburg, Germany, after which he 
worked for several years as a research 
fellow on silicon heterojunction solar cells 
at the Helmholtz Centre Berlin for 
Materials and Energy. After a sabbatical 
leave in Nanjing, China, Rolf joined SERIS 
in April 2011. He has (co-)authored many 
scientific papers and holds several patents 
in the area of wafer-based silicon solar cells.
