Kodi galasi la photovoltaic ndi chiyani?
Maselo a dzuwa a kristalo a silicon ali ndi mphamvu zochepa zamakaniko ndipo amatha kuphulika mosavuta. Mpweya wonyowa ndi wowononga womwe uli mumlengalenga umawonjezera pang'onopang'ono ndikuwononga ma electrode, zomwe zimapangitsa kuti asathe kupirira zovuta za ntchito yakunja. Chifukwa chake, maselo a dzuwa nthawi zambiri amasungidwa ndi galasi la photovoltaic kudzera mu EVA ndi gulu lakumbuyo. Galasi la photovoltaic lomwe lili mu gawo la photovoltaic limateteza batri ku kukokoloka kwa mpweya wa m'madzi, kuletsa mpweya kuti usawonongeke, kukana kutentha kwambiri, 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 m'maselo a silicon a crystalline ndi losiyana ndi galasi loyandama. Pamwamba pa galasi la photovoltaic ndi suede, kotero kuti kuwala komwe kumafika pamwamba pa module sikophweka kutulutsa chiwonetsero chagalasi. Pansi pake ndi pamwamba pake, zomwe zingapangitse mphamvu yolumikizirana ndi filimu ya EVA kukhala yolimba.
Zipangizo zazikulu zopangira galasi la photovoltaic ndi mchenga wa quartz, phulusa la soda, miyala yamwala, dolomite, sodium nitrate, mirabilite, sodium pyroantimonate, aluminiyamu hydroxide ndi zina zotero. Mchenga wa quartz umagwira ntchito makamaka ngati thupi lopanga maukonde, mlingo nthawi zambiri umatenga zigawo zambiri zagalasi, 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 yowumba galasi ikwaniritse zofunikira pakuwumba, ntchito ya mirabilite makamaka ngati chowunikira, chomwe chimagwiritsidwa ntchito kuchotsa thovu mugalasi, kuti chipereke kutumiza kwa galasi.
Chiŵerengero cha kugwiritsa ntchito zinthu zopangira galasi la photovoltaic
Njira yokonzekera galasi la photovoltaic nthawi zambiri imakonzedwa pogwiritsa ntchito njira yowerengera, momwe njira yopangira ingagawidwe m'magawo awiri: kupanga pepala losaphika ndi kukonza mozama; Kupanga zinthu zopangira kumaphatikizapo kuphatikiza, kusungunula, kupotoza, kuponda ndi kudula. Pafupifupi 1100 ℃ pakupotoza, galasi losungunuka, lozungulira ndi kuzizira, limafika pamlingo winawake, m'lifupi mwake, kapangidwe kena, kudzera mu galasi la 91.5%, kenako litaponda, galasi limakhala ndi mawonekedwe okhazikika, kuti likhale ndi mphamvu inayake, losavuta kusweka, lothandiza kudula, kukonza galasi. Tiyenera kunena kuti mizere yopanga magalasi opangidwa ndi photovoltaic ndi magalasi oyandama ndi yosiyana, ngati kufunikira kwa galasi la photovoltaic sikokwanira kusintha mwachindunji kuchokera ku mzere wopanga magalasi oyandama.
Njira yogwiritsira ntchito kwambiri nthawi zambiri imakhala yopangira galasi loyambirira ndi lolimba, lophimba limapangitsa kuti galasi liziyenda bwino, lolimba limapangitsa kuti galasi liziyenda bwino, ndipo pambuyo polimbitsa, mphamvu yopindika ya galasi imakhala yofanana ndi galasi wamba nthawi 3-5, mphamvu yogwira ntchito imakhala yofanana ndi galasi wamba nthawi 5-10, komanso chitetezo chimawonjezeka.
Kuyenda kwa njira yagalasi ya photovoltaic
Kugwira ntchito kwa galasi la photovoltaic kumafuna kuti galasi la photovoltaic likhale ndi kuwala kokwanira. Kawirikawiri, kuwala kwa chitsulo chosaphimbidwa (kutalika kwa mafunde kuyambira 380nm mpaka 1100nm) nthawi zambiri kumakhala pamwamba pa 91%, pomwe kwa galasi lophimbidwa pambuyo pokonza mozama kumatha kufika 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 solar — gawo 1 lopangidwa ndi galasi loyera kwambiri, kugwira ntchito kochepa kwa galasi la photovoltaic 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 kumafunika kusonkhanitsa chidziwitso kwa nthawi yayitali komanso njira imodzi yopangira, ndipo kumafunika ndalama zoyambira zazikulu, mphamvu ya matani 900 patsiku uvuni wa photovoltaic umafunika 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 m'manja mwa mabizinesi otsogola, ndipo makampaniwa alibe mphamvu zaukadaulo komanso mphamvu zachuma zomangira matani 1000 a uvuni wosungunuka tsiku lililonse.
