Free Keithley Web-Based Seminar Explores Electrical Measurements of Photovoltaic/Solar Cell Devices

Keithley Instruments, Inc. (NYSE: KEI), a world leader in advanced electrical test instruments and systems, will broadcast a free, web-based seminar titled "Photovoltaic Measurements: Testing the Electrical Properties of Today’s Solar Cells” on Thursday, December 10, 2009. This one-hour seminar will provide an overview of the electrical measurements used in photovoltaic device development from basic research to early production testing. To register for this event, visit www.keithley.com/events/semconfs/webseminars.

In addition to the underlying theory of how solar cells work, this web-based seminar will focus on the physical measurements required to characterize them, as well as on cell properties that can be inferred from test results. Topics will include both capacitance-voltage (C-V) and current-voltage (I-V) characterization, including DC and pulse techniques, as well as common measurements of a cell’s efficiency. The event will conclude with a text-based Q&A session.

Participants in the seminar will learn about the measurements required to characterize photovoltaic devices, the types of device information electrical characterization can provide, and special system considerations for test labs.

Registration Information.

"Photovoltaic Measurements: Testing the Electrical Properties of Today’s Solar Cells” will be broadcast on Thursday, December 10, at 15:00 CET (9:00 a.m. EST) for the European audience and at 2:00 p.m. EST for the North American audience. The event is free to the public, but participants must register in advance at www.keithley.com/events/semconfs/webseminars.
