Understanding the key characteristics and performance parameters of photovoltaic (PV) cells—such as the current-voltage (I-V) behavior, maximum power point (MPP), fill factor, and energy conversion efficiency—is essential for optimizing solar energy systems.
The main parameters that are used to characterize the performance of solar cells are short circuit current, open circuit voltage, maximum power point, current at maximum power point, the voltage at the maximum power point, fill factor, and efficiency.
Photovoltaic modules (Figure 2) are interconnected solar cells designed to generate a specific voltage and current. The module's current output depends on the surface area of the solar cells in the modules. Figure 2. A flat-plate PV module. This module has several PV cells wired in series to produce the desired voltage and current.
Under STC the corresponding solar radiation is equal to 1000 W/m2 and the cell operating temperature is equal to 25oC. The solar cell parameters are as follows; Short circuit current is the maximum current produced by the solar cell, it is measured in ampere (A) or milli-ampere (mA).
Fig. 1. The manufacturer's data sheet presents information about the PV module such as open circuit voltage (Voc), short circuit current (Isc), peak power (Pmax), voltage and current at maximum peak point (Vmpp, Impp) at different indoor conditions such as the standard test condition (STC) as well as the nominal operating cell temperature (NOCT).
PV cell parameters are usually specified under standard test conditions (STC) at a total irradiance of 1 sun (1,000 W/m2), a temperature of 25°C and coefficient of air mass (AM) of 1.5. The AM is the path length of solar radiation relative to the path length at zenith at sea level. The AM at zenith at sea level is 1.
