TUTORIAL
Young Scientist Tutorial on Characterization Techniques for Thin-Film Solar Cells
Monday March 28, 2005
1:30 PM - 5:00 PM
Room 2005 (Moscone West)
This tutorial is intended for young researchers (including
students and post-graduates within three years of degree completion)
that are new in the field of thin-film solar cells and want
to learn the fundamentals of characterization methods that
are being utilized in the research and development of these
materials and devices. The tutorial will begin with an introduction
to thin-film solar cells based on copper indium diselenide,
cadmium telluride, and silicon thin-films and critical materials
and device issues. This will be followed by more detailed
presentations focusing on four specific characterization techniques
being used to address these issues:
(1) Transmission electron microscopy (TEM)
(2) X-ray Fine Structure Studies at Synchrotron Sources
(3) Admittance Measurements
(4) Hall-Effect Measurements
The presentations on characterization techniques will be
given by young researchers who are active in the characterization
of thin-film solar cells. Because the presentations will focus
on the characterization techniques rather than the specific
materials, the tutorial, should be of broad interest to participants
of other symposia.
A unique aspect of this tutorial is that it will primarily
be presented by students and young researchers for students
and young researchers. It is believed that a more open atmosphere
for discussion of ideas will be facilitated by the absence
of senior scientists in the session. Scientific exchange and
discussion between students will be encouraged by the lecture-style
presentations and by having sufficient time allotted for discussions.
