Solar Cell Performance Measurement System





Team Astros has undertaken the task of designing and implementing a Solar Cell performance measurement system for Dr. David Zubia, assistant professor in the Electrical and Computer Engineering (ECE) Department at the University of Texas at El Paso (UTEP). This system will measure current and voltage (IV) characteristics of test solar cells and will perform analysis and data logging.


The system is comprised of the following subsystems:
The program will provide the user with a GUI to enter the appropriate test parameters to obtain the IV characteristics of a test solar cell. This cell, illuminated by the light source, will be subjected to a voltage sweep via the LabVIEW program in conjunction with the data acquisition board. During this voltage sweep, measurements of the voltage across the cell and the current generated by it will be acquired, analyzed, plotted and saved to a tab-delimited file for later importation into 3rd party software (e.g. Microsoft Excel, Access, etc.) for later analysis.

Method of Completion

The work was divided among the three team members in the following manner:


The current issues that the team must deal for the completion of this project are:



Test solar cells shall be characterized the week of November 18th, 2002. These cells will be stressed under certain lighting conditions and re-characterized in order to evaluate any performance degradation. Once the system is proven reliable to the Senior Project coordinators, Teaching Assistant, Dr. Zubia and the end user, the system will be turned over to the end user for full use.
