A Study of the Effects
of Processing Variations on the Performance of Silicon
by Dr. J. Shawn Addington and Cadet David T. Wagner
cells convert solar power to electrical power through
the photovoltaic effect. In this research, a variety of
single-crystalline silicon solar cells are designed, fabricated,
and tested to determine the effect of varying processing
conditions on the overall performance of the cells. First,
an overview of the photovoltaic effect and solar cell
fundamentals will be presented. Next, current-voltage
characteristics are presented and compared for a variety
of solar cells, including n-type and p-type cells, as
well as cells that have been fabricated using different
dopant diffusion process schedules. Some preliminary discussion
of front surface contact design optimization and antireflective
coatings will also be presented. Finally, the presentation
will conclude with current research efforts to optimize
J. Shawn Addington is the Jamison-Payne Institute Professor
and Head of the Electrical and Computer Engineering Department
at the Virginia Military Institute. He earned his BS,
MS, and Ph.D. degrees in electrical engineering from Virginia
Tech. At VMI, he developed two new programs in Microelectronics
and Semiconductor Devices which have since supported approximately
two dozen undergraduate research projects. Dr. Addington
has published and presented research in the area of engineering
pedagogy, is a member of several professional and honor
societies, and is a registered professional engineer in
the Commonwealth of Virginia.
David Wagner is a senior at Virginia Military Institute
majoring in Electrical and Computer Engineering. He is
from Mooresville, North Carolina and plans on commissioning
into the Air Force upon graduation focusing on Developmental
Engineering. David has been doing research on optoelectronics
focusing on semiconductor devices for the past year. He
is a student member of the IEEE and is also a member of
Eta Kappa Nu.
