The LabView program displays a Solar Emulator panel (Figure 3) used to conduct the Solar Cell testing. The Voc, Isc, Vmp and Imp values for four I-V curves are listed above the Working I-V Curve display. An adjacent Selector selects one curve for download. A Preview display to the right shows all four curves when the Preview button is clicked. When the Download to Unit button (under the Preview display) is clicked, then the selected curve is downloaded and displayed as a dashed line in the Working I-V Curve display to show it is waiting to be executed. When the Execute Waiting Curve is clicked, the emulation starts and the Working I-V curve changes from a dashed line to a solid line. A cursor formed by the intersection of vertical and horizontal lines is green while the emulation is working and red when it is stopped. Realtime values for voltage setpoint and measured current appear in the windows above and to the right of the Working I-V Curve display, while the values for Voc, Isc, Vmp and Imp are shown at the left and bottom of Working I-V curve display.The Stop Emulation button stops the emulation, and the Stop VI button closes the panel window and exits the application.
