Selo ya dzuwa ya silicon yokhala ndi kristalo ili ndi mphamvu yochepa ya makina ndipo imatha kuphulika mosavuta. Mpweya wonyowa ndi wowononga womwe uli mumlengalenga umasungunuka pang'onopang'ono ndikuwononga ma electrode, omwe sangathe kupirira zovuta zogwirira ntchito panja. Pachifukwa ichi, ma cell a dzuwa nthawi zambiri amapakidwa ndi galasi la photovoltaic kudzera mu EVA ndi kumbuyo. Galasi la photovoltaic m'magawo a photovoltaic kuti ateteze batri ku kukokoloka kwa madzi ndi mpweya, kuletsa mpweya kuti apewe okosijeni, kukana kutentha kwambiri komanso kotsika, kutchinjiriza bwino komanso kukana kukalamba. Galasi la photovoltaic ndi mtundu wa galasi la silicate lokhala ndi chitsulo chochepa, lomwe limadziwikanso kuti galasi loyera kwambiri.
Galasi la photovoltaic lomwe limagwiritsidwa ntchito mu selo la kristalo la silicon ndi losiyana ndi galasi loyandama. Pamwamba pa galasi la photovoltaic ndi suede, zomwe zimapangitsa kuti kuwala kukhale kovuta kuti kuwonekere mwachindunji pamwamba pa module. Pansi pake pali embossed, zomwe zingawonjezere mphamvu ya zomatira ndi filimu ya EVA.
Zigawo zazikulu za galasi la photovoltaic
Zipangizo zazikulu zopangira galasi la photovoltaic ndi mchenga wa quartz, phulusa la soda, miyala yamwala, dolomite, sodium nitrate, mchere wa glauber, sodium pyroantimonate, aluminium hydroxide, ndi zina zotero. Mchenga wa quartz umagwira ntchito makamaka ngati thupi lopangidwa ndi netiweki, mlingo nthawi zambiri umatenga gawo lalikulu la galasi, phulusa la soda limagwiritsidwa ntchito makamaka kupereka sodium oxide, makamaka kuchepetsa kutentha kwa galasi; Ntchito yayikulu ya miyala yamwala ndikusintha kukhuthala kwa galasi kukhala koyenera, kuti nthawi yopangira galasi ikwaniritse zofunikira pakuumba, mchere wa glauber umagwiritsidwa ntchito makamaka ngati clarifier, womwe umagwiritsidwa ntchito kuchotsa thovu mu galasi, kuti upereke kutumiza kwa galasi.
Chiŵerengero cha kugwiritsa ntchito zinthu zopangira galasi la photovoltaic
Galasi la Photovoltaic nthawi zambiri limakonzedwa pogwiritsa ntchito njira yowerengera, ndipo njira yopangira imatha kugawidwa m'magawo awiri: kupanga mapepala ndi kukonza mozama. Kupanga koyambirira kumaphatikizapo kuphatikiza, kusungunula, kukonza, kuyika ndi kudula. Pafupi 1100 ℃, galasi losungunuka, lozungulira ndi lozizira, limafika pamlingo winawake, m'lifupi mwake, kapangidwe kena, kudzera mugalasi la 91.5%, kenako litayikidwa, galasi limakhala ndi mawonekedwe okhazikika, omwe ndi olimba, osavuta kusweka, omwe ndi abwino kudula, kukonza galasi. Ndikofunikira kunena kuti pali kusiyana pakati pa mzere wopanga wa galasi lopangidwa ndi photovoltaic ndi galasi loyandama.
Njira yogwiritsira ntchito kwambiri nthawi zambiri imakhala yopangira galasi loyambirira ndi kulimbitsa, kuphimba kumathandizira kupititsa patsogolo kufalikira kwa galasi la photovoltaic, kulimbitsa kumawonjezera mphamvu zamakina za galasi, mphamvu yopindika ya galasi lolimba ndi kuwirikiza katatu mpaka kasanu kuposa ya galasi wamba, mphamvu yokhudza ndi kuwirikiza kasanu mpaka khumi kuposa ya galasi wamba, kulimbitsa mphamvu komanso kupititsa patsogolo chitetezo.
Kuyenda kwa njira yagalasi ya photovoltaic
Kugwira ntchito kwa galasi la photovoltaic la 02 kumafuna kuti galasi la photovoltaic likhale ndi kuwala kokwanira. Kawirikawiri, kuwala kwa pepala lachitsulo losaphimbidwa (kutalika kwa mafunde kuyambira 380nm mpaka 1100nm) nthawi zambiri kumakhala kopitilira 91%, pomwe kuwala kwa galasi lophimbidwa pambuyo pokonza mozama kumatha kufika pa 93.5%. Kuphatikiza apo, galasi la photovoltaic liyenera kukwaniritsa kukana kwa nyengo ndi mphamvu zina zamakanika. Malinga ndi GB T 30984.1-2015 "galasi la mphamvu ya dzuwa gawo 1 lopangidwa ndi galasi loyera kwambiri", kugwira ntchito kochepa kwa galasi la photovoltaic lomwe limagwiritsidwa ntchito pama module a photovoltaic kuyenera kukwaniritsa zofunikira izi.
Makampani opanga magalasi a Photovoltaic ku China
Zopinga zamakampani opanga magalasi a photovoltaic ndizokwera, kuchuluka kwa magetsi ndi kwakukulu, kupanga kumafuna kusonkhanitsa chidziwitso kwa nthawi yayitali komanso njira imodzi yopangira, ndipo kumafuna ndalama zoyambira zazikulu, mphamvu ya matani 900 patsiku uvuni wa photovoltaic galasi ikufunika ndalama zoyambira RMB 9, matani 550 a ndalama zophikira zimatenga pafupifupi 3-400 miliyoni yuan, ndipo uvuni waukulu unali ndi mtengo wotsika wopanga poyerekeza ndi uvuni wamba (kugwiritsa ntchito mphamvu zochepa mpaka 20%). Zotsatira zake, makampani opanga magalasi a photovoltaic ali ndi mphamvu yoonekeratu, ndipo ukadaulo wambiri wosungunuka makamaka uli m'manja mwa mabizinesi otsogola, Mabizinesi ang'onoang'ono ndi apakatikati alibe mphamvu zaukadaulo komanso mphamvu zachuma zoti azigwiritsa ntchito pomanga matani 1000 a uvuni.
Kuyambira pamene China idaswa malire aukadaulo opanga magalasi a photovoltaic mu 2006, makampani opanga magetsi a photovoltaic akutukuka mofulumira pasanathe zaka 10. Pambuyo podalira kwathunthu zinthu zochokera kunja, China yakhala wopanga magalasi a photovoltaic ambiri padziko lonse lapansi. Ma module a silicon a kristalo opitilira 90% padziko lonse lapansi amagwiritsa ntchito magalasi a photovoltaic opangidwa ku China. Poyerekeza ndi mabizinesi akunja, magalasi a photovoltaic aku China ali ndi ubwino woonekeratu pa khalidwe ndi mtengo. Pofika mu Disembala 2017, pali zinthu 24 zagalasi loyera kwambiri, ma uvuni 40 ndi mizere 135 yopangira ku China, yokhala ndi mphamvu yonse yopangira matani 21,290 patsiku. Powerengedwa malinga ndi kuchuluka kwa zokolola zapakati pamakampani a 78%, kupanga magalasi oyera kwambiri a ultra-calented-glass osaphika ndi pafupifupi matani 14,773.20 patsiku.
Zoyembekeza za msika
Chaka cha 2018 chidzakhala chaka choyamba choyambitsa zinthu ziwiri, ndipo gawo la msika wa zinthu ziwiri lidzawonjezeka mofulumira, zomwe zidzapangitsa kuti galasi la photovoltaic lifunike. Malinga ndi kuwerengera, kufunika kwa galasi la photovoltaic kukuwonetsedwa patebulo lotsatira. Poganizira kuti ma uvuni ena akale agalasi la photovoltaic amafunika kukonzedwa kozizira mu 2018, mphamvu yeniyeni yopangira galasi la photovoltaic idzakhala yotsika kuposa mphamvu yopangira yokha, ndipo kupezeka ndi kufunikira kwa galasi la photovoltaic mu 2018 kuli bwino kwambiri.
Malinga ndi zotsatira zake, kuyambira kotala lachinayi la 2017, kuchuluka kwa magetsi a photovoltaic glass kunali kochepa, kumayambiriro kwa chaka cha 2018, pansi pa mfundo ya makampani a photovoltaic mu kotala loyamba ndi nthawi yopuma, kukwera kwa mtengo wa magalasi a photovoltaic, pepala lophimba mu 31 yuan pa mita imodzi kapena kuposerapo, mtengo wa galasi mu 21 yuan pa mita imodzi kapena kuposerapo, mtengo wa kubwereranso kwa mitengo kudzapangitsa kuti magetsi a photovoltaic glass enterprise akhale abwino kwambiri.
