PV cells are mainly classified into two types: i) organic solar cells and ii) silicon (Si) based inorganic solar cells. Still, the Si-based solar cells are most demanding in the market of photovoltaic cells due to their durability and high efficiency of approximately 15–20% ( Karim et al., 2019, Mehmood et al., 2016a ).

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.
The relationship between the two might need to be adjusted for the resistances of the wires, as in the example we described above, but overall the four-wire measurement is a way to accurately get current and voltage information of a device. A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell.
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.
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.
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.
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.
