Why are PV glass covers prone to dust?
However, during long-term outdoor application, PV glass covers are prone to accumulate dusts on the surface. Then the layers of dust deposition obstruct or alter incoming light, which result in unequal light transmission through PV glass covers and reduce power generation and efficiency of PV modules.
What is a PV glass cover?
Photovoltaic (PV) cells are one of significant approaches to solve this challenge. In general, PV glass covers, as the crucial component of PV modules with the function of protecting PV cells from damage, are composed of tempered glass with low iron contents and ultra-white glosses or suede surfaces .
Why should PV glass covers be coated with self-cleaning films?
The dust deposition layers also increase heat transfer resistance and impact heat dissipation, potentially leading to PV modules burnout in extreme conditions. To eliminate the effect of dusts and residual dirt, PV glass covers should be coated with self-cleaning transparent films.
Can SLS glass be used in PV modules?
SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement. In the current paper, we have reviewed the state of the art and conclude that improvements to PV modules can be made by optimizing the cover glass composition.
Why is glass front sheet important for PV modules?
In addition to optical and environmental performance, the mechanical performance of PV modules is also of vital importance, and with the glass front sheet constituting a high proportion of the mass of PV modules, it also impacts on mechanical properties of the PV module composite.
Do PV modules have a reflection loss?
PV modules experience reflection losses of ∼4% at the front glass surface. This loss can be mitigated by the use of anti-reflection coatings, which now cover over 90% of commercial modules.
