Meeting Announcement:

A Study of the Effects of Processing Variations on the Performance of Silicon Solar Cells

Presented by Dr. J. Shawn Addington and Cadet David T. Wagner


Abstract

Solar 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 cell performance.

Biographies

Dr. 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.

The Virginia Mountain Section (VMS) of the IEEE has been serving members in the Southwest corner of the Commonwealth of Virginia since 1949.

We currently have two Student Branches in local universities and colleges:

  • Virginia Military Institute
  • Virginia Tech

and the VMS Consultants Network Affinity Group

The purpose of this Affinity Group is to share information concerning consulting opportunities, and to make a list of consultants and their areas of expertise available to potential employers.

Anyone wishing to be added to this group, or desiring more information should contact David Livingston, d.livingston@ieee.org.

Information about our Section, the Chapters, and material of interest to our members may be found by selecting items in the left column of this page.
