6 FAQs about [Solar cell testing steps]

How do I test a solar cell?

How do you calibrate a solar cell?

For the calibration of a solar cell, the cell area, the spectral responsivity (SR) and the current–voltage (I–V) curve have to be determined. The I–V curve then yields the characteristic parameters, including the power conversion efficiency, fill factor, short-circuit current and open-circuit voltage.

How do you measure solar cell efficiency?

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.

How do you calculate the spectral responsivity of a solar cell?

Since the pixel area is known from the previous calibration, the area of the sample under test, or the area of the mask used to define the active solar cell area, can be calculated. To determine the spectral responsivity of the DUT, the relative DSR is measured between 280 and 1,200nm in 10nm steps at 25°C.

How are solar cells measured?

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.

How do I choose a solar cell contacting scheme?

No explicit standard exists for the design of the solar cell contacting scheme. The IEC 60904-1 recommends a four-wire connection at the cell busbars, and a note in this standard states that it is advisable to choose the contacting method appropriate to the intended use of the cell or of the measurement.
