How does deterioration affect the lifespan of photovoltaic cells?
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).
Do small cracks affect the performance of a-Si photovoltaic cells?
It was noted that the a-Si cell showed an abrupt reduction in its efficiency (−92.77%) when the first crack (which had reduced dimensions) was formed. Thus, it appears that the formation of a small crack has a great impact on the performance of this photovoltaic technology.
