An I-V curve measurement is performed by applying a series of voltages to the device. At each voltage, the current flowing through the device is measured. The supplied voltage is measured by a voltmeter connected in parallel to the device, and the current is measured by an ammeter connected in series. An example of.

Short circuit current, Isc, flows with zero external resistance (V= 0) and is the maximum current delivered by the solar cell at any illumination level. Similarly, the open circuit voltage, Voc, is the potential that develops across the terminals of the solar cell when the external load resistance is very large (Figure 3).
When it comes to testing the performance of solar cells, accurate measurements and reliable equipment are essential. The fundamental way to test your solar cell performance is by taking a current-voltage (I-V or J-V) measurement.
Several key properties of a solar cell can be extracted from its I-V curve, including it''s open circuit voltage (V OC), short-circuit current (J SC) and fill factor (FF), all of which can be used to find the solar cell efficiency.

To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment. Additionally, many potential solar cell materials are unable to withstand weathering effects during the early stages of development. For these reasons
When it comes to testing the performance of solar cells, accurate measurements and reliable equipment are essential. The fundamental way to test your solar cell performance is by taking a current-voltage (I-V or J-V) measurement.

For example, a solar cell may be tested between -1 V and 1 V, whilst an LED may use a higher range of 0 V to 10 V. Sometimes applying a voltage can alter the electronic properties of a device. This can cause the current to change over time, even when the voltage is kept constant.
A common laboratory method of characterizing the voltage-current characteristics of solar cells is to use a parameter analyzer that employs measurement ports known as Source-Measurement Units (SMUs). Each SMU is capable of providing a known voltage and measuring the resulting current or vice versa.
A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell. A variable load is applied across the four wires in order to get a variety of current and voltage measurements for the device under test. Exactly what current and voltage is unknown until tested, which is why there is some iteration needed.
Solar cell parameters gained from every I-V curve include the short circuit current, Isc, the open circuit voltage, Voc, the current Imax and voltage Vmax at the maximum power point Pmax, the fill factor (FF), and the power conversion efficiency of the cell, η [2–6].
However, a much more practical method is to measure the current and voltage response of the device under broadband light, which removes the need to manually integrate (sum) all the individual pieces. IEC 60904-1 specifies the standard procedure for measuring current and voltage characteristics of photovoltaic devices.
Most solar cell IV measurement software, such as the Ossila Solar Cell IV software, will ask you to input device active area. This means the output measurement is given as a JV curve from which device metrics can be easily worked out. Firstly, you must ensure the correct positioning of your testing system under your solar simulator.
