Photovoltaic glass belongs to the branch of glass manufacturing in the specific application field of photovoltaics, which is a technology- and capital-intensive industry. At present, the photovoltaic glass in the industry mainly adopts the ultra-white embossing process, which is quite different from the rolled glass that was used for architectural decoration in the early days with low technical content.
| characteristic | Photovoltaic glass | Ordinary glass |
| Iron content | 0.015%--0.02% | Generally more than 0.2% |
| Visible light transmittance | ≥91.5%, ≥91.0% in the spectral range of 300-2500nm (equivalent to 3mm standard original degree) | The same thickness is about 88-89%, about 80 degrees |
| High temperature resistance | It can withstand surface high temperature above 500 degrees | Not resistant to acid and alkali corrosion, not resistant to bad weather and harmful gases |
| Undercoating resistance | It has certain corrosion resistance to rainwater and harmful gases in the environment; it is resistant to cleaning by various cleaning agents, and it is resistant to wiping by acid and alkali cleaning agents; long-term exposure to hydrogen and sunlight will not cause serious deterioration in performance. | Relatively weak impact resistance |
| Impact resistance | Tempered treatment, high strength, good impact resistance |
