Pico AmmeterIn this mode, analyzer works as an Ideal ammeter (voltage drop < 5 μV) tomeasure short circuit current of solar cell.
Potentiostat
In this mode, analyzer measures current under a constant voltage given by user.
Voltage, Current, Power or Resistance is displayed onscreen. It is also possible toplot those parameters against time.
I-V Tracer
In this mode, user can select START, END, and STEP voltages and scan condition(desired scan speed, scan time, or holding time). Analyzer plots current and powervs. voltage curves. Calculated results include Voc, Isc, Jsc, Pmax, Vmpp, I mpp, FF, Rs,RSH, ƞactiveA, and ƞgeoA . Advanced I-V option allows to set initial, middle, and end
point holding times. Also plots I vs. t transient curve for all data points and/or
under a selected fixed voltage.
Maximum Power Point Tracking (MPPT)In this mode, analyzer acts like the best load for solar cell to extract maximum
power and keep tracking MPP continuously. Plots the Pmax ,Vmpp , Impp andEfficiency vs. time curves and also displays current/power vs. voltage plots.
