Main Functions

Solar Cell I-V curve Tracing
PV I-V

User selectable START, END and STEP voltages. Plots current and power vs. voltage curves. Calculated results include Voc, Isc, Jsc, Pmax, Vmpp, I mpp, FF, Rs, RSH, ƞactiveA, and ƞgeoA . User can set the desired scan speed, scan time, or holding time. Advanced I-V option allows initial, middle, and end point holding times. I vs. t transient plot for all data points and/or under a selected fixed voltage.

Maximum Power Point Tracking (MPPT)
MPPT

Analyzer acts like the best load for the cell to extract maximum power and keep tracking MPP continuously. Plots Pmax ,Vmpp , Impp and Efficiency vs. time curves and also display current/power vs. voltage plots. In addition user can directly measure the open circuit voltage, short circuit current and plot the current vs. time under a given fixed output voltage.

Four Quadrant I-V Analysis
4QD I-V User selectable START, END, STEP voltages and SCAN SPEED (mV/s). Plot current vs. voltage curve for given number of voltage sweep cycles in potentiostat mode. Can be use in 3 electrodes liquid cell with reference electrode.
Four Probe Resistance Measurements
4Pro Ohm Three special functions included to easily measure sheet resistance, resistivity, and resistance. Geometric correction factors are automatically calculated according to size and measuring probe location on the sample which are entered as parameters. Measurement range 2.0 x 10-3 to 5.0 x 106 Ω .
