Reverse Golden Lamulo - chitirani ena momwe amakuchitirani - akutanthauza kuti mukhale otsogolera popanga ma silicons akulu.
Mu chithunzi chagalasi cha zomwe United States yakhala ikuchita ndiukadaulo wa semiconductor lithography, China yasintha posachedwapa malamulo ake kuti aletse kutumizira kunja kwaukadaulo wambiri wamagetsi adzuwa kuti apitilize kukhala otsogola komanso msika wapadziko lonse lapansi.
A solar panelPadenga pakhoza kukhala zidutswa zana za silicon ndipo China ndiyomwe ikutsogolera pamakina opangira izi.Tsopano opanga aku China aletsedwa kugwiritsa ntchito matekinoloje awo akuluakulu a silicon, silicon yakuda ndi cast-mono silicon kunja kwa dziko, malinga ndi malangizo omwe angosinthidwa kumene omwe atulutsidwa ndi Unduna wa Zamalonda ndi Unduna wa Sayansi ndi Ukadaulo.
Makampani aku China amapanga zoposa 80% zapadziko lonse lapansimapanelo a dzuwandi ma modules koma adakumana ndi misonkho yolemetsa yoperekedwa ndi United States pazaka khumi zapitazi.
Ena mwa iwo adasamutsa malo awo ku Thailand ndi Malaysia kuti apewe msonkho koma Beijing sakufuna kuti atengere matekinoloje awo apamwamba kunja.
Akatswiri aukadaulo adati China ikufuna kulepheretsa India kukhala imodzi mwazinthu zazikulu padziko lonse lapansi zopangira zida zamagetsi zamagetsi.
Mu 2011, dipatimenti yazamalonda ku US idagamula kuti China idataya ma solar pamsika waku US.Mu 2012, idakhazikitsa ntchito pamagetsi adzuwa aku China.
Ena opanga ma solar aku China adasamukira ku Taiwan kuyesa kuthawa mitengoyi koma US idakulitsa mitengo yake kuti igwiritse ntchito pachilumbachi.
Kenako anasamukira ku Cambodia, Malaysia, Thailand ndi Vietnam.Juni watha, olamulira a Biden adati achotsa msonkhomapanelo a dzuwazotumizidwa ku US kuchokera kumayiko anayiwa kwa miyezi 24.
Pofuna kuletsa makampani ambiri aku China kusamutsa matekinoloje awo a silicon kutsidya lina, unduna wa zamalonda ku China mwezi watha udaganiza zophatikizira matekinolojewa pamalangizo ake otumiza ndi kutumiza kunja.
Izi zitha kumveka ngati kutseka chitseko kavalo atatuluka m'khola, koma sizili choncho.Makampani mwina adasamutsa makina ena kunja kuti apange silicon yayikulu - koma akafuna magawo, makina ndi chithandizo chaukadaulo sangathenso kugula kuchokera ku China.
Beijing idaganizanso zoletsa kutumiza kunja kwa dziko la laser radar, kusintha ma genome ndi ukadaulo waulimi woswana.Kukambirana ndi anthu kudayamba pa Disembala 30 ndikutha pa Januware 28.
Pambuyo pokambirana, makampani azamalonda adaganiza zoletsa kutumiza kunja kwasilicon wamkulu, silicon wakuda ndi cast-monomatekinoloje a passivated emitter ndi rear cell (PERC).
Wolemba nkhani waku China wa ku China adati ma silicon akulu akulu pakati pa 182mm ndi 210mm adzakhala okhazikika padziko lonse lapansi chifukwa msika wawo udakula kuchoka pa 4.5% mu 2020 mpaka 45% mu 2021 ndipo mwina akwera mpaka 90% mtsogolomo.
Anatinso makampani aku China omwe amayesa kupanga ma silicon akulu kutsidya lina akhudzidwa ndi chiletso chatsopanocho chifukwa mwina sangathe kugula zida zofunika ku China.
Mu gawo la solar panel, ma silicon ang'onoang'ono amatanthawuza omwe ali pa 166mm kapena pansi.Chidutswa cha silicon chokulirapo, chimachepetsa mtengo wopangira magetsi.
A Song Hao, wothandizira wachiwiri kwa purezidenti wa GCL Technology, omwe amagulitsa zida zamagetsi zamagetsi pamakampani oyendera dzuwa, adati ngakhale kuletsa kutumiza kunja kukalepheretsa makampani aku China kukula kunja sikungalepheretse kutumiza katundu wawo kuchokera ku China.
Song adati zinali zomveka kuti dziko la China liletse kutumizidwa kwa matekinoloje apamwamba kwambiri a solar popeza maiko ambiri otukuka adachitanso zofanana ndi China m'mbuyomu.
Lu Jinbiao, wachiwiri kwa director wa komiti yaukadaulo ya Silicon Viwanda ku China Nonferrous Metals Industry Association, adati kuletsa kutumiza kunja kwa China.silicon wakuda ndi matekinoloje a cast-mono PERCsangakhale ndi vuto lalikulu pamakampani chifukwa sagwiritsidwanso ntchito.
Lu adati zimphona zambiri zaku China zopangira solar, kuphatikiza Longi Green Energy Technology, JA Solar Technology ndi Trina Solar Co, zidasuntha kale njira zawo zopangira ku Southeast Asia zaka ziwiri zapitazi.Anatinso makampaniwa akumana ndi zoletsa ngati akufuna kugula ng'anjo za kristalo kapena zida zodulira zida za silicon kuchokera ku China kuti apange ma silicon akulu.
Yu Duo, wowunikira mphamvu ya dzuwa ku Oilchem.net, adati India idakhazikitsa njira zatsopano zothandizira omwe amapanga zida zoyendera dzuwa chaka chatha pofuna kuchepetsa kudalira kwawo zinthu zaku China.Anati China ikufuna kulepheretsa India kupeza matekinoloje ake.
