Solar Cell Characterization; Set Up The Solar Cell I-V Sweep From The Front Panel - Keithley Interactive SourceMeter 2450 User Manual

Section 9: Measuring I-V characteristics of solar cells

Solar cell characterization

This application demonstrates how to use the Model 2450 to characterize a solar cell. The examples
show how to use the front panel, SCPI code over a remote interface, and TSP code over a remote
interface.
For this test, you will:
•
Reset the instrument.
•
Select the source voltage function and measure current function.
•
Set the current limit.
•
Select four-wire (remote sense) mode.
•
Set up and generate a voltage sweep.
•
Initiate the trigger model, which will turn the output on.
•
Record the measurements.
•
After the voltage sweep is complete, turn off the output.
•
Retrieve the measurements.
•
View the data on the front-panel graph.

Set up the solar cell I-V sweep from the front panel

This is an example of an I-V test that sweeps voltage from 0 V to 0.55 V in 10 mV steps and
measures the resulting current. You can then view the data on the graph screen.
You must control the light source for this application.
