2. PV module attenuation Based on NREL-SAM’s outdoor attenuation analysis of more than 2000 PV modules worldwide, the attenuation rate of the module after the second year will change linearly. The 25 year attenuation rate is between 8% and 14% (Figure 5).
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.
Therefore, the accuracy of this fitting model was proven as it portrays, simultaneously, the behavior of photovoltaic cells in the absence and presence of degradation. The crystalline silicon cell is a rigid structure, and the remaining studied technologies are flexible.
The FF (Fill Factor) is a parameter that informs about the quality of the photovoltaic cell. It is defined as the ratio of the maximum power of the cell to the theoretical maximum power field [24–28].
The PV cell efficiency is the ratio of electric power output to input. You might find these chapters and articles relevant to this topic.
