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.
