Ndi kupita patsogolo kwaukadaulo komanso kutsika kwamitengo yazinthu, msika wapadziko lonse lapansi wa photovoltaic upitilira kukula mwachangu, ndipo kuchuluka kwa zinthu zamtundu wa n m'magawo osiyanasiyana kukuchulukiranso mosalekeza.Mabungwe angapo amaneneratu kuti pofika chaka cha 2024, mphamvu yatsopano yopangira magetsi padziko lonse lapansi ikuyembekezeka kupitilira 500GW (DC), ndipo gawo la magawo a batri amtundu wa n lipitilira kukula kotala lililonse, ndipo gawo lomwe likuyembekezeka kupitilira 85% kumapeto kwa chaka.
Chifukwa chiyani zinthu zamtundu wa n zimatha kumaliza ukadaulo mwachangu chotere?Ofufuza kuchokera ku SBI Consultancy adanena kuti, kumbali imodzi, chuma cha nthaka chikuchepa kwambiri, zomwe zimafunika kupanga magetsi oyeretsera pamadera ochepa;Komano, pamene mphamvu ya n-mtundu zigawo za batire ikuwonjezeka mofulumira, kusiyana kwa mtengo ndi mankhwala a p-mtundu kumachepa pang'onopang'ono.Kuchokera pamalingaliro amitengo yamitengo kuchokera kumabizinesi angapo apakati, kusiyana kwamitengo pakati pa zigawo za np za kampani yomweyi ndi 3-5 cents/W zokha, kuwonetsa kukwera mtengo.
Akatswiri aukadaulo akukhulupirira kuti kutsika kosalekeza kwa ndalama zogulira zida, kuwongolera kwachangu kwazinthu, komanso kupezeka kwamisika yokwanira kumatanthauza kuti mtengo wazinthu zamtundu wa n upitilira kutsika, ndipo pakadali njira yayitali yochepetsera ndalama ndikuwonjezera mphamvu. .Panthawi imodzimodziyo, akugogomezera kuti teknoloji ya Zero Busbar (0BB), monga njira yothandiza kwambiri yochepetsera ndalama komanso kuwonjezereka bwino, idzagwira ntchito yofunika kwambiri pamsika wa photovoltaic wamtsogolo.
Kuyang'ana mbiri ya kusintha kwa ma gridlines a cell, ma cell oyambilira a photovoltaic anali ndi mizere yayikulu 1-2 yokha.Pambuyo pake, ma gridline anayi akuluakulu ndi ma gridline akuluakulu asanu adatsogolera pang'onopang'ono machitidwe amakampani.Kuyambira theka lachiwiri la 2017, ukadaulo wa Multi Busbar (MBB) unayamba kugwiritsidwa ntchito, ndipo pambuyo pake udapangidwa kukhala Super Multi Busbar (SMBB).Ndi mapangidwe a ma gridlines akuluakulu 16, njira yotumizira ma gridlines akuluakulu imachepetsedwa, kuonjezera mphamvu zonse zotulutsa zigawozo, kuchepetsa kutentha kwa ntchito, ndikupangitsa kuti magetsi apangidwe kwambiri.
Pamene ntchito zambiri zimayamba kugwiritsa ntchito zigawo zamtundu wa n, pofuna kuchepetsa kugwiritsira ntchito siliva, kuchepetsa kudalira zitsulo zamtengo wapatali, ndi kuchepetsa mtengo wopangira, makampani ena a chigawo cha batri ayamba kufufuza njira ina - Zero Busbar (0BB) teknoloji.Zimanenedwa kuti teknolojiyi imatha kuchepetsa kugwiritsidwa ntchito kwa siliva ndi 10% ndikuwonjezera mphamvu ya gawo limodzi ndi oposa 5W mwa kuchepetsa mthunzi wa kutsogolo, wofanana ndi kukweza mlingo umodzi.
Kusintha kwaukadaulo nthawi zonse kumayendera limodzi ndi kukweza kwa njira ndi zida.Zina mwa izo, zomangira monga zida zoyambira zopangira zida zimagwirizana kwambiri ndi chitukuko chaukadaulo wa gridline.Akatswiri aukadaulo adanenanso kuti ntchito yayikulu ya stringer ndikuwotcherera riboni ku cell kudzera pakuwotcha kwapamwamba kwambiri kuti apange chingwe, chokhala ndi ntchito ziwiri za "kulumikizana" ndi "kulumikizana kwa mndandanda", komanso mtundu wake wowotcherera ndi kudalirika mwachindunji. kukhudza zokolola za msonkhano ndi zizindikiro za mphamvu zopanga.Komabe, ndikukwera kwaukadaulo wa Zero Busbar, njira zowotcherera zachikhalidwe zakhala zosakwanira ndipo zikuyenera kusinthidwa mwachangu.
Apa ndipamene ukadaulo wa Little Cow IFC Direct Film Covering umatuluka.Zimamveka kuti Zero Busbar ili ndi ukadaulo wa Little Cow IFC Direct Film Covering, womwe umasintha njira wamba wowotcherera zingwe, imathandizira njira yolumikizira ma cell, ndikupanga mzere wopanga kukhala wodalirika komanso wowongolera.
Choyamba, ukadaulo uwu sagwiritsa ntchito solder flux kapena zomatira popanga, zomwe zimapangitsa kuti pasakhale kuipitsa komanso zokolola zambiri pakuchitapo kanthu.Imapewanso kutsika kwa zida chifukwa chokonza solder flux kapena zomatira, motero kuonetsetsa kuti nthawi yayitali kwambiri.
Kachiwiri, ukadaulo wa IFC umasuntha njira yolumikizira zitsulo kupita kumalo opangira laminating, kukwaniritsa kuwotcherera munthawi yomweyo gawo lonse.Kuwongolera kumeneku kumapangitsa kuti kutentha kukhale kofananako, kumachepetsa kutayika, komanso kumapangitsa kuti mawotchi azikhala abwino.Ngakhale kutentha kusintha zenera la laminator ndi yopapatiza pa siteji iyi, kuwotcherera zotsatira akhoza kuonetsetsa ndi optimizing filimu zakuthupi zigwirizane ndi chofunika kuwotcherera kutentha.
Chachitatu, pamene kufunikira kwa msika wa zida zamphamvu kwambiri kukukula komanso kuchuluka kwa mitengo yamagulu kumachepa pamitengo yamagulu, kuchepetsa kufalikira kwa ma intercell, kapenanso kugwiritsa ntchito masitayilo olakwika, kumakhala "kachitidwe".Chifukwa chake, zigawo za kukula kofanana zimatha kupeza mphamvu zapamwamba zotulutsa, zomwe ndizofunikira kwambiri pakuchepetsa mtengo wazinthu zopanda silicon ndikupulumutsa ndalama za BOS.Zimanenedwa kuti ukadaulo wa IFC umagwiritsa ntchito maulumikizidwe osinthika, ndipo ma cell amatha kusungidwa mufilimuyo, kuchepetsa kufalikira kwa ma intercell ndikukwaniritsa ming'alu yobisika ya zero pansi pamipata yaying'ono kapena yoyipa.Kuonjezera apo, riboni yowotcherera siyenera kuphwanyidwa panthawi yopanga, kuchepetsa chiopsezo cha kuwonongeka kwa selo panthawi ya lamination, kupititsa patsogolo zokolola za kupanga ndi kudalirika kwa gawo.
Chachinayi, ukadaulo wa IFC umagwiritsa ntchito riboni yowotcherera yotsika kutentha, kuchepetsa kutentha kolumikizana kukhala pansi pa 150.°C. Izi zatsopano zimachepetsa kwambiri kuwonongeka kwa kupsinjika kwa kutentha kwa maselo, mothandiza kuchepetsa kuopsa kwa ming'alu yobisika ndi kusweka kwa mabasi pambuyo pa kupatulira kwa selo, ndikupangitsa kukhala ochezeka kwa maselo oonda.
Pomaliza, popeza ma cell a 0BB alibe mizere yayikulu ya gridi, kulondola kwa malo a riboni yowotcherera ndikochepa, kupangitsa kuti chigawocho chikhale chosavuta komanso chogwira ntchito bwino, ndikuwongolera zokolola pang'ono.M'malo mwake, mutatha kuchotsa mizere yayikulu yakutsogolo, zigawozo ndizokongola kwambiri ndipo zadziwika kwambiri ndi makasitomala ku Europe ndi United States.
Ndikoyenera kutchula kuti ukadaulo wa Little Cow IFC Direct Film Covering umathetsa bwino vuto lankhondo pambuyo pakuwotcherera ma XBC.Popeza ma cell a XBC amakhala ndi ma gridline mbali imodzi yokha, kuwotcherera kwa zingwe zotentha kwambiri kumatha kuyambitsa kugundana kwakukulu kwa maselo pambuyo pakuwotcherera.Komabe, IFC imagwiritsa ntchito ukadaulo wophimba filimu yotsika kutentha kuti muchepetse kupsinjika kwamafuta, zomwe zimapangitsa kuti zingwe zosalala komanso zosapindika za cell zitaphimbidwe ndi filimu, kuwongolera kwambiri mtundu wazinthu komanso kudalirika.
Zikumveka kuti pakali pano, makampani angapo a HJT ndi XBC akugwiritsa ntchito teknoloji ya 0BB m'zigawo zawo, ndipo makampani angapo otsogolera a TOPCon awonetsanso chidwi ndi lusoli.Zikuyembekezeka kuti mu theka lachiwiri la 2024, zinthu zambiri za 0BB zidzalowa mumsika, ndikulowetsa mphamvu zatsopano mu chitukuko chathanzi komanso chokhazikika chamakampani a photovoltaic.
