Mechanism analysis of anti-PID effect exerted by anti-PID effect component

Since the weatherability of glass is mainly affected by the migration of sodium ions, the faster the migration, the more the glass is damaged. The migration of sodium ions can be inhibited by the tin oxide layer, and the weather resistance of the glass surface and the weather resistance of the AR coating film can be obviously improved. Further suppressing the occurrence of PID. And the photoelectric conversion efficiency of the crystalline silicon photovoltaic module is improved.

Analysis of the mechanism of the PID effect resistance of the assembly provided in example 1 shows that, as shown in FIG. 6, hydrogen ions contained in the water vapor and salt mist in the air can be replaced with sodium calcium ions in the glass and then with CO in the air₂The calcium carbonate generated by the reaction is deposited on the surface of the glass, and the light transmittance and the appearance of the glass are influenced. Conventional anti-reflective (AR) coatings even exacerbate such phenomena. In the assembly provided by the example 1 for resisting the PID effect, the tin oxide layer can inhibit the migration of sodium ions and calcium ions in the glass, and the excessive migration is avoidedAnd the anti-PID effect is exerted, and the appearance of the component is maintained.

In summary, the present application provides a component for resisting PID effect, wherein the component for resisting PID effect comprises a glass substrate and tin oxide layers disposed on either side of the glass substrate. The formation of the PID effect is mainly characterized in that a glass substrate contains a large amount of sodium ions and calcium ions, and the sodium ions, the calcium ions and hydrogen ions in water are exchanged to form a series of reactions to cause the generation of the PID effect, and a tin oxide layer is arranged on any surface of the glass substrate, so that the ionic radius of the tin ions is smaller than that of the sodium ions and the calcium ions, the ionic potential energy is stronger, the binding capacity with oxygen atoms is stronger, the glass network structure can be enhanced, the glass network structure is more compact, the migration of the sodium ions and the calcium ions is limited, carbonates containing the sodium ions and the calcium ions are not formed on the surface of the glass, the glass is protected from serious erosion, the weather resistance of the surface of the glass and a glass coating film can be obviously improved, and the generation of the PID attenuation effect on the upper surface of the glass is effectively reduced; meanwhile, the tin oxide layer has small influence on the light transmittance of the whole glass, so that the obtained assembly has strong PID effect resistance, excellent integral performance and wide application.
