The exact measurement of area of a solar cell is also open to debate, but for now we''ll leave those details to others. Standardized Tests of Solar Cells Because there is a great deal of work both commercial and academic in the field of photovoltaics, there is also a great need for standardization of the methods and means of comparing one device to another.
Cell measurements at NREL include spectral responsivity and current versus voltage (I-V) of one sun, concentrator, and multijunction devices. Reference cell measurements also include linearity of short-circuit current and total irradiance. We use I-V measurement systems to assess the main performance parameters for PV cells and modules.
Measurement uncertainties of the solar cell parameters can be stated. A calibration certificate is issued. Solar cells with calibration certificates may be used as references to, for example, establish traceability of production line output. The determination of the spectral response of a device is always necessary if a device is to be calibrated.

Inappropriate solar cell measurement conditions can thus result in the overestimation of module performance when the CTM P losses due to interconnection of the solar cells in the module layout are not considered.

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.
There are three metrics which will determine solar cell efficiency: the open circuit voltage (V OC), the short circuit current (J SC), and the fill factor (FF). When measuring solar cells, we often refer to current density, J, rather than just current, I. This allows researchers to compare devices with different active areas.
A silicon reference solar cell (NREL, USA) is used for adjustment of the intensity of solar simulators for 1 sun intensity condition and should match the certified I sc value of reference solar cell. The reference solar cell possesses a certificate of calibration for all parameters, i.e.,
