Iseli lelanga le-silicon elicwebezelayo ngokwalo linamandla amancane okusebenza futhi livame ukuqhekeka. Umswakama namagesi agqwalisayo emoyeni azogqwala kancane kancane i-electrode, engakwazi ukumelana nezimo zokusebenza ezinzima emoyeni ovulekile. Ngenxa yalesi sizathu, amaseli elanga avame ukupakishwa ngengilazi ye-photovoltaic nge-EVA kanye nephaneli yangemuva. Ingilazi ye-photovoltaic kumamojula e-photovoltaic ukuvikela ibhethri emanzini nasegesini, ivimbele umoya-mpilo ukuvimbela i-oxidation, ukumelana nokushisa okuphezulu nokuphansi, ukuvikela okuhle kanye nokumelana nokuguga. Ingilazi ye-Photovoltaic uhlobo lwengilazi ye-silicate enokuqukethwe okuphansi kwensimbi, eyaziwa nangokuthi ingilazi emhlophe kakhulu.
Ingilazi ye-photovoltaic esetshenziswa kuseli le-crystal silicon ihlukile kunengilazi entantayo. Ingxenye engenhla yengilazi ye-photovoltaic iyi-suede, okwenza kube nzima ukuthi ukukhanya kungene ngqo ebusweni be-module ukukhiqiza ukubonakaliswa kwe-specular. Ingxenye engezansi i-embossed, okungathuthukisa amandla okunamathela ngefilimu ye-EVA.
Izingxenye eziyinhloko zengilazi ye-photovoltaic
Izinto eziyinhloko zokusetshenziswa kwengilazi ye-photovoltaic zifaka isihlabathi se-quartz, umlotha we-soda, i-limestone, i-dolomite, i-sodium nitrate, usawoti we-glauber, i-sodium pyroantimonate, i-aluminium hydroxide, njll. Isihlabathi se-Quartz sidlala indima yomzimba wokwakheka kwenethiwekhi, umthamo uvame ukuthatha ingxenye enkulu yengilazi, umlotha we-soda usetshenziswa kakhulu ukuhlinzeka nge-sodium oxide, ikakhulukazi ukunciphisa izinga lokushisa lokuncibilika kwengilazi; Indima eyinhloko ye-limestone ukulungisa i-viscosity yengilazi ibe nenani elifanele, ukuze isikhathi sokubumba ingilazi sihlangabezane nezidingo zokubumba, usawoti we-glauber usetshenziswa kakhulu njenge-clarifier, esetshenziselwa ukususa amabhamuza engilazini, ukunikeza ukudluliselwa kwengilazi.
Isilinganiso sokusetshenziswa kwezinto zokusetshenziswa kwengilazi ye-photovoltaic eluhlaza
Ingilazi ye-Photovoltaic ivame ukulungiswa ngendlela yokucubungula i-calendar, futhi inqubo yokukhiqiza ingahlukaniswa ngezigaba ezimbili: ukukhiqizwa kweshidi kanye nokucubungula okujulile. Ukukhiqizwa kokuqala kufaka phakathi ukuhlanganisa, ukuncibilikisa, ukucubungula i-calendar, ukuhlanganisa i-annealing kanye nokusika. Cishe i-1100 ℃ enkambisweni yokugoqa, ingilazi encibilikisiwe, ama-calendar roller ajikeleza futhi apholile, ngesivinini esithile afinyelela ukujiya okuthile, ububanzi obuthile, iphethini ethile, ngengilazi yesilinganiso esingu-91.5%, bese kuthi ngemva kokufaka i-annealing, ingilazi ibe nejika lokucindezeleka elizinzile, ukuze ibe namandla athile, akulula ukuphuka, ilungele ukusika, ukucubungula ingilazi. Kubalulekile ukuphawula ukuthi kukhona umehluko phakathi komugqa wokukhiqiza wengilazi embossed ye-photovoltaic kanye nengilazi entantayo.
Inqubo yokucubungula ejulile ivame ukuba yi-glass coating yokuqala kanye ne-toughening, i-coating iwukuthuthukisa ukudluliselwa kwengilazi ye-photovoltaic, i-toughening iwukwandisa izakhiwo ze-mechanical zengilazi, amandla okugoba kwengilazi eqinile aphindwe ka-3 ~ 5 kunangengilazi evamile, amandla okushaya aphindwe ka-5 ~ 10 kunangengilazi evamile, ukuthuthukisa amandla kodwa futhi nokuthuthukisa ukuphepha.
Ukugeleza kwenqubo yengilazi ye-Photovoltaic
Ukusebenza kwengilazi ye-photovoltaic engu-02 kudinga ukuthi ingilazi ye-photovoltaic kumele ibe nokudlulisa ukukhanya okuhle. Ngokuvamile, ukudlulisa ukukhanya kweshidi lensimbi elingagqokwanga (ububanzi be-wavelength kusuka ku-380nm kuya ku-1100nm) kuvame ukuba ngaphezu kuka-91%, kuyilapho ukudlulisa ukukhanya kwengilazi egqokwe ngemva kokucubungula okujulile kungafinyelela ezingeni lika-93.5%. Ngaphezu kwalokho, ingilazi ye-photovoltaic idinga ukuhlangabezana nokumelana nesimo sezulu esithile kanye nezakhiwo zemishini. Ngokusho kwe-GB T 30984.1-2015 “ingilazi yamandla elanga ingxenye 1 embossed ultra-white”, ukusebenza okuncane kwengilazi ye-photovoltaic esetshenziselwa amamojula e-photovoltaic kufanele kuhlangabezane nezidingo ezilandelayo.
Imboni yengilazi ye-Photovoltaic eShayina
Izithiyo zemboni yengilazi ye-photovoltaic ziphakeme, ukuhlushwa kuphakeme, ukukhiqizwa kudinga ukuqongelela ulwazi lwesikhathi eside kanye nenqubo yokukhiqiza eyodwa, futhi kudinga ukutshalwa kwezimali kokuqala okukhulu, umthamo wamathani angu-900 ngosuku i-photovoltaic glass kiln idinga ukutshalwa kwezimali kokuqala RMB 9, amathani angu-550 okutshalwa kwezimali kwesitofu kuthatha cishe ama-yuan ayizigidi ezingu-3-400, kanti i-kiln enkulu yayinezindleko zokukhiqiza eziphansi uma kuqhathaniswa ne-kiln evamile (ukusetshenziswa kwamandla aphansi kuya ku-20%). Ngenxa yalokho, imboni yengilazi ye-photovoltaic inomphumela ocacile wesikali, futhi inani elikhulu lobuchwepheshe obuncibilikisiwe ikakhulukazi ezandleni zamabhizinisi aholayo, Amabhizinisi amancane naphakathi nendawo awanawo amandla obuchwepheshe namandla ezomnotho okutshala imali ekwakhiweni kwamathani ayi-1000 ama-kiln.
Selokhu iShayina yephula umkhawulo wezobuchwepheshe wokukhiqizwa kwengilazi ye-photovoltaic ngo-2006, imboni ye-photovoltaic yasekhaya ithuthuke ngokushesha eminyakeni engaphansi kweyi-10. Ngemva kokuthembela ekuthengisweni kwempahla kwamanye amazwe ngokuphelele, iShayina isibe ngumkhiqizi omkhulu kunabo bonke emhlabeni wengilazi ye-photovoltaic. Amamojula e-silicon ekristalu angaphezu kwama-90% emhlabeni asebenzisa ingilazi ye-photovoltaic ekhiqizwa eShayina. Uma kuqhathaniswa namabhizinisi angaphandle, ingilazi ye-photovoltaic yaseShayina inezinzuzo ezisobala ngekhwalithi kanye nezindleko. Kusukela ngoDisemba 2017, kunemikhiqizo yengilazi ye-calented emhlophe kakhulu engu-24, ama-kiln angu-40 kanye nemigqa yokukhiqiza engu-135 eShayina, enekhono lokukhiqiza eliphelele elingamathani angu-21,290 ngosuku. Uma kubalwa ngokwesilinganiso sezinga lesivuno semboni esingu-78%, ukukhiqizwa kwasekhaya kwezingcezu zengilazi ye-calented emhlophe kakhulu kungaba ngamathani angu-14,773.20 ngosuku.
Okulindelwe yimakethe
Unyaka ka-2018 uzoba unyaka wokuqala wokwethulwa kwezingxenye ezinezinhlangothi ezimbili, futhi isabelo semakethe sezingxenye ezinezinhlangothi ezimbili sizokhula ngokushesha, okuzoqhuba ngempumelelo isidingo sengilazi ye-photovoltaic. Ngokusho kokubala, isidingo sengilazi ye-photovoltaic siboniswe kuthebula elilandelayo. Uma sibheka ukuthi amanye ama-oven amadala engilazi ye-photovoltaic adinga ukulungiswa okubandayo ngo-2018, amandla okukhiqiza angempela engilazi ye-photovoltaic azoba ngaphansi kwamandla okukhiqiza ajwayelekile, futhi ukunikezwa kanye nesidingo sengilazi ye-photovoltaic ngo-2018 kusezingeni eliqinile.
Ngokusho kwemiphumela, kusukela ku-Q4 2017, ukunikezwa kwengilazi ye-photovoltaic kanye nesidingo esiqinile, ekuqaleni kuka-2018, ngaphansi kwesisekelo semboni ye-photovoltaic kwikota yokuqala akusebenzi, kunciphisa ukukhuphuka kwentengo yengilazi ye-photovoltaic, ishidi lokumboza ku-31 yuan ngemitha yesikwele noma ngaphezulu, intengo yengilazi ku-21 yuan ngemitha yesikwele noma ngaphezulu, intengo yokubuyela emuva kwamanani izokwenza izinga le-gross margin lebhizinisi lengilazi ye-photovoltaic lithuthuke kakhulu.
