The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
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.
This deterioration compromises the lifespan of PV cells as it increases the difficulty of dissipating heat. Experimental tests of two degradation types (formation of cracks and formation of bubbles) were carried out on different photovoltaic technologies (c-Si, a-Si, CIGS and organic perovskite cells).
In this context, it will be investigated the impact of degradation on the performance of four photovoltaic technologies (c-Si, a-Si, CIGS and organic perovskite cells). Therefore, experimental tests of two different degradation conditions were carried out: formation of cracks and formation of bubbles.
Photovoltaic cells degradation is the progressive deterioration of its physical characteristics, which is reflected in an output power decrease over the years. Consequently, the photovoltaic module continues to convert solar energy into electrical energy although with reduced efficiency ceasing to operate in its optimum conditions.
Aging of the photovoltaic cell and the various types of degradation have several repercussions on cell’s electric characteristics . Thus, its parasitic resistances are affected (with an increase in series resistance, R s, and a decrease in shunt resistance, R sh) as well as its transmittance (τ) that suffers a reduction.

In the paper, we propose and describe an algorithm for degradation trend evaluation, a new concept of multiple "time- and degradation pattern-dependent" degradation factors. The proposed method has been calibrated and validated using different PV modules and systems data of 5 to 35 years of field exposure.
