There are several methods used to characterize solar cells. The most common and essential measurement you can take is the current-voltage (I-V) sweep. From this, you can calculate all the necessary device metrics needed to work out the efficiency of your solar cell. The I-V sweep is a quick measurement.
Three main measuring systems are required for the calibration of solar cells: one to determine the active area, another to determine the spectral responsivity, and a third one to measure the I–V characteristics.
The measured values for voltage, current and temperature are recorded by separate and externally triggered calibrated multimeters. Both n- and p-type solar cells with edge lengths between 20 and 175mm and short-circuit currents of up to 15A are measured. Figure 2. CalTeC’s I–V curve measurement facility.
You can effortlessly test the efficiency of your solar cell device using the Ossila Solar Cell Testing Kit — which combines our solar simulator with our source measure unit and test board. There are several methods used to characterize solar cells. The most common and essential measurement you can take is the current-voltage (I-V) sweep.
Abstract: The key technique for measuring the Ampere-Volt (I-V) characteristic of a solar cell is to control the electronic load. In this paper, a new technique for measuring the I-V characteristics of solar cells is proposed.
Another trusted way of measuring the ideality factor of a solar cell is by doing a light intensity study. To do this, you measure a J-V curve from the solar cell at various fractions and/or multiples of 1 Sun, and the linear relationship between V OC and light intensity will give you the ideality factor.
