Usluga Život Od Solar Paneli

The service life of solar panels is determined by the materials of the panels, tempered glass, EVA, TPT, etc. Generally, the service life of solar panels made by manufacturers who use better materials can reach 25 years, but with the impact of the environment, the materials of solar panels will age over time. Generally, the power will be reduced by 30 percent after 20 years of use, and by 70 percent after 25 years of use.
Slicing, čišćenje, preparation of antilop, periferno jetkanje, uklanjanje OF PN plus spojnice on the back, fabrication of gornji and donje elektrode, fabrication of antireflection films, sintering, testiranje i grading are 10 koraci.
Specific proizvodnja proces upute za solarne ćelije
(1) Rezanje: Using multi žica rezanje, the silicon štap is cut into square silicon pločice.
(2) Cleaning: Clean the silicon wafer using conventional cleaning methods, and then remove the damaged layer on the surface of the silicon wafer by 30-50 um using an acid (or alkali) solution.
(3) Priprema of a teksturiran površina: Anisotropni bakropis of a silikon wafer with an alkali solution is used to prepare a textured surface on the surface of the silicon wafer.
(4) fosfor difuzija: Using a premaz izvor (or a liquid source, or a solid fosfor nitride sheet source) for difuzija, a PN plus junction is form, s a junction depth općenito of 0}.3 to 0.5 um.
(5) Periferno jetkanje: The difuzija sloj formiran on the periferna površina of the silicij wafer til tijek tijek difuzija can kratki spoj the gornji i donje elektrode of the baterija, i the periferne difuzije sloj can be uklonjeno ma maskiranje mokro jetkanje or plazma suho jetkanje.
(6) Remove the the back PN plus knot. Wet bakropis or brušenje je obično korišteno to remove the PN plus junction on the back.
(7) Fabrication of gornji i donje elektrode: Using vakuum isparavanje oplata, elektroless nikal oplata, or aluminij pasta tisak and sinteriranje procesi . First, make the lower electrode, and then make the gornja elektroda. Aluminij pasta tisak is a široko korištena proces metoda.
(8) Making antireflection films: To reduce the loss of incoming reflection, a layer of antireflection film should be covered on the surface of the silicon wafer. The materials used to produce antireflection films include MgF2, SiO2, Al2O3, SiO, Si3N4, TiO2, Ta2O5, etc. The process method can be vacuum coating method, ion coating method, sputtering method, printing method, PECVD method, or spraying method.
(9) Sintering: Sintering a baterija čip onto a nikal or bakar podloga.
(10) Test classification: According to the specified parameter specifications, test classification.
