SUNDAY, JUNE 16TH, 8:30 AM – 12:00 PM
AM1. PHOTOVOLTAICS 101/201
(
MR 11-12)
Instructor:
Dr. Christiana Honsberg, Global Institute of
Sustainability, Arizona State University
Synopsis:
An introductory tutorial in photovoltaic principles
and devices. Basic semiconductor physics will be covered,
with an emphasis on semiconductor junctions. The basic
current-voltage relationship for a solar cell will be derived.
Performance optimization and various loss mechanisms
for the general solar cell will be discussed. The course is
designed for those with a background in physics, chemistry,
and/or engineering, but not yet having a strong background
in semiconductor devices.

Energy Conversion, University of Delaware
Synopsis:
Thin film semiconductors have been investigated
as absorber layers for large scale photovoltaic since the
1960’
s based on the promise of low manufacturing cost
for large-area high-throughput PV modules. Three thin film
absorber materials emerged in the 1980’s as being technically
and commercially viable for solar cells: CdTe, CuInSe2-
based, and Si-based. The first two are polycrystalline while
the Si films are either amorphous or nanocrystalline. Each is
configured as a multilayer heterojunction device fabricated
on glass, foil, or plastic substrates. Sustained worldwide
research and development have significantly increased
our understanding of the materials chemistry and physics
leading to advanced device structures and high-throughput
processing at high yield. Each technology has the benefits
common to thin films but each has specific challenges.
In this tutorial, we will provide an overview of the basic
processing sequence, device structures, manufacturing
options, and key challenges for each thin film technology.
Based on our 3 decades of direct involvement in thin film
PV, we will review the evolution of each thin film technology
into today’s commercial success and identify critical issues
limiting wider commercialization. The course is intended for
graduate students, researchers, technologists and managers
interested in an overview of the technologies as well as
understanding the fundamental materials chemistry, device
operation and characterization and process engineering
