13 Sollar Cell
13.4 Solar Cell DLCP: Solar Cell drive-level capacitance profiling
(A.05.03.2013.0124_2013.02.27.1)
[Supported Analyzer]
B1500A
[Description]
Measures the anode-cathode capacitance (Cp)-DC bias output(Vdc) characteristics of the solar cell with
sweeping the signal level (Vac), and plots the drive-level density (Ndl) - the depletion width (W) characteristics.
Vdc is changed from VdcStart to VdcStop in VdcStep steps. Vac is swept for the peak-to-peak voltage Vpp to
change from VppStart to VppStop in VppStep steps. The maximum and minimum value of the applied voltage
should be kept Vdc, Vdc-Vpp respectively. The CMU performs Vdc sweep measurement of the parallel
capacitance (Cp) and conductance (G) at each signal level.
