Quick data screening & simple manipulation for your solar cell study



Identifying electrical properties and performance of solar cells is important to researchers and manufacturers who contribute to improving the cell efficiency and energy conversion. Current-voltage (IV) characterization of solar cells is a generic method to verify the performance of cells, which provides several important parameters, including short-circuit current (Isc), open-circuit voltage (Voc), max power (Pmax= Imax ✕ Vmax), current of max power (Imax), voltage of max power (Vmax), fill factor (FF), energy conversion efficiency (η), series resistance (Rs) and shunt resistance (Rsh). Figure 1 shows a typical I-V curve of solar cell in the dark or illuminated environments. The short-circuit current (Isc) is the current through a solar cell when the voltage across the cell is zero (short circuited, V=0). When the current through the cell is zero (I=0), the related voltage here is referred to as the open-circuit voltage (Voc), which is the maximum voltage of the cell. The max power point (Vmax, Imax) indicates the maximum power generated by solar cells.

Experimental setup


Figure 2 shows the equivalent circuit of using Elite- EDC for I-V characterization of solar cells. To measure the IV characteristics of solar cells, Elite- EDC is set up to generate a sweep voltage source on solar cells and record the relationship between current and voltage.


Figure 3 shows how to connect the test solar cell to an Elite-EDC. 

1. Connect positive (+) terminal of solar cells to Elite- Vin and -Vout

2. Connect negative (-) terminal to Elite-Iin

3. Choose I-V curve mode on the UI (user interface) page, set up parameter and record data.
