c-2vsv-solarcell test

Make sure the solar cell is connected to the 4210-CVU (see 4210-CVU connections (on page 4-5)).

This test uses a CVU to perform a capacitance-voltage sweep on a solar cell. Capacitance is

measured on each step of the sweep. A graph (1/C

and C versus V) is generated from the collected

data. The Formulator calculates 1/C

and the doping density.

c-2vsv-solarcell Analyze sheet

The test data is displayed in the Analyze sheet:

• Cp_AC: Measured parallel capacitance.

• Gp_AC: Measured conductance.

• DCV_AC: Forced DC bias voltage.

• F_AC: Forced test frequency.

• CVU1S: Status code for each measurement. Rows highlighted in blue indicate a fault. For details,

see Measurement status (on page 6-191

• Formulas: Formulator calculation results.

AC = Anode to cathode.

cfsweep test

Make sure the PV cell is connected to the 4210-CVU (see 4210-CVU connections (on page 4-5)).

This test performs a frequency sweep, measuring capacitance at each frequency point, and then

generates a C versus F graph.
