When comparing the performance of two solar cells, it is common to normalize the current by dividing by the illuminated cell area. In this way, the current density values are compared. Current is expressed as Amps (or milliAmps, mA); current density is expressed as mA cm-2.
This has a power density of 100 mW.cm -2 and is equivalent to average solar irradiation at mid-latitudes (such as in Europe or the USA). To ensure reliability and control during testing of solar cells, a solar simulator can be used to generate consistent radiation. AM0 and AM1.5 solar spectrum.
The current density (JSC) is fixed for a given sunlight intensity and it does not depend on the area. Let’s take an example where we have to calculate the output current of the solar cell having an area of 20 cm2 and 50 cm2. Having a constant current density of 35 mA/m2.
As can be seen from table 1 and figure 2 that the open-circuit voltage is zero when the cell is producing maximum current (ISC = 0.65 A). The value of short circuit depends on cell area, solar radiation on falling on cell, cell technology, etc. Sometimes the manufacturers give the current density rather than the value of the current.

This is known as the power conversion efficiency (PCE) and is the ratio of incident light power to output electrical power.
The value of VOC depends on cell technology and the operating temperature of the cell. Maximum power point represents the maximum power that a solar cell can produce at the STC (i.e. solar radiance of 1000 W/m2 and cell operating temperature of 25oC). It is measured in WPeak or simply WP.

The generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the incident photon has an energy greater than that of the band gap.
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect.
