From I-V curve the efficiency of the cell is proportional to the value of the three main photovoltaic parameters: short circuit current Isc, open circuit voltage V.c, fill factor FF and efficiency rl have been determined.
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
Efficiency is the ratio of output power (pout) to input power (Pin) where the conversion efficiency is the output electric power divided by the result of solar irradiation (E) and the surface area (A) of the solar panel. Multiplying the measured output voltage and current equal to the output power , . ...
The PV cell efficiency is the ratio of electric power output to input. You might find these chapters and articles relevant to this topic. Waldemar Kuczynski, Katarzyna Chliszcz, in Renewable and Sustainable Energy Reviews, 2023 When the solar cell is lit, a potential difference occurs between the electrodes.
The PV cell efficiency is inversely proportional to the temperature due to the band gap properties of silicon, which is due to the inherent characteristics of the solar cell. When temperature increases, the reverse saturation current of the solar cell increases and thereby reduces the open circuit voltage of the cell.
This reduces the fill factor and the efficiency of the solar cell [115,116]. To some extent, this efficiency reduction can be lowered by trimming the reflection of the incident solar light.
