VK-PA-100
Features of Solar Cell I-V Tracer
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.
Features of Maximum Power Point Tracking (MPPT) Function
Analyzer acts like the best load for the cell to extract maximum power point (MPP) and keep tracking MPP continuously. Plots Pmax ,Vmpp , Impp and Efficiency vs. time curves and also display current/power vs. voltage plots.
Features of Full Range I-V Function
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 used in 3 electrodes liquid cell with reference electrode.
Four Probes Resistance Measurement
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 .
