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.
The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Here’s how to calculate the power the solar cell delivers to the motor: The maximum theoretical power from our solar cell, Pmax, is the product of the Voc and Isc.
Once you have the power for each resistance setting, you can graph it. I have found that the most understandable way to read the power output of a solar cell is to use an X/Y (scatter) plot , with voltage along the horizontal axis and power on the vertical axis. The graph above is constructed from the sample data.
First, calculate the solar power arriving at the solar cell by multiplying the intensity of the sun by the area of the solar cell. The solar intensity from the sun, Si, over a given area at the surface of the earth is approximately 1,000 watts/m 2. Use a ruler to measure the active area, A, of your solar cell (see photo below).
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
The contacting to the solar cell is implemented as a four-wire configuration. A four-quadrant power supply is used for the measurement of the solar cell I–V curve. The current is measured by means of a voltage measurement across calibrated high-power precision shunt resistors.
