Ngokuthuthuka kwezobuchwepheshe kanye nokwehla kwezintengo zemikhiqizo, isikali semakethe ye-photovoltaic yomhlaba wonke sizoqhubeka sikhula ngokushesha, futhi ingxenye yemikhiqizo yohlobo lwe-n emikhakheni ehlukahlukene nayo ikhula ngokuqhubekayo.Izikhungo eziningi zibikezela ukuthi ngo-2024, umthamo osanda kufakwa wokukhiqiza amandla kagesi we-photovoltaic kulindeleke ukuthi udlule u-500GW (DC), futhi ingxenye yezingxenye zebhethri yohlobo lwe-n izoqhubeka nokukhula ngekota ngayinye, ngesabelo esilindelekile esingaphezu kuka-85% ekupheleni konyaka.
Kungani imikhiqizo yohlobo lwe-n ingaqeda ukuphindaphinda kwezobuchwepheshe ngokushesha kangaka?Abahlaziyi be-SBI Consultancy baveze ukuthi, ngakolunye uhlangothi, izinsiza zomhlaba ziya ngokuya zintuleka, okwenza kudingeke ukuthi kukhiqizwe ugesi ohlanzekile kakhulu ezindaweni ezilinganiselwe;ngakolunye uhlangothi, ngenkathi amandla ezingxenye zebhethri zohlobo lwe-n ekhula ngokushesha, umehluko wentengo ngemikhiqizo yohlobo lwe-p uya uyancipha kancane kancane.Ngokombono wezintengo zamabhidi avela kumabhizinisi athile amaphakathi, umehluko wentengo phakathi kwezingxenye ze-np zenkampani efanayo kuphela amasenti angu-3-5/W, okugqamisa ukusebenza kahle kwezindleko.
Ochwepheshe bezobuchwepheshe bakholelwa ukuthi ukwehla okuqhubekayo kokutshalwa kwezimali kwemishini, ukuthuthukiswa okuqhubekayo kokusebenza kahle komkhiqizo, kanye nokutholakala kwemakethe okwanele kusho ukuthi intengo yemikhiqizo yohlobo lwe-n izoqhubeka nokwehla, futhi kusenendlela ende okufanele ihanjwe ekunciphiseni izindleko kanye nokwandisa ukusebenza kahle. .Ngesikhathi esifanayo, bagcizelela ukuthi ubuchwepheshe be-Zero Busbar (0BB), njengendlela ephumelela kakhulu yokunciphisa izindleko nokwandisa ukusebenza kahle, kuzodlala indima ebaluleke kakhulu emakethe ye-photovoltaic ezayo.
Uma sibheka umlando wezinguquko kumigqa yegridi yeseli, amaseli e-photovoltaic okuqala ayenemigqa yegridi eyinhloko engu-1-2 kuphela.Kamuva, olayini begridi abane abakhulu kanye nemigqa emihlanu emikhulu kancane kancane bahola inkambiso yemboni.Kusukela engxenyeni yesibili ka-2017, ubuchwepheshe beMulti Busbar (MBB) baqala ukusetshenziswa, futhi kamuva bathuthukiswa baba yiSuper Multi Busbar (SMBB).Ngokuklanywa kwemigqa yegridi eyinhloko engu-16, indlela yokudluliswa kwamanje kolayini begridi abakhulu iyancishiswa, okwandisa amandla okukhipha ewonke ezingxenye, ukwehlisa izinga lokushisa lokusebenza, futhi kubangele ukuphehlwa kukagesi okuphezulu.
Njengoba amaphrojekthi amaningi aqala ukusebenzisa izingxenye zohlobo lwe-n, ukuze kuncishiswe ukusetshenziswa kwesiliva, ukunciphisa ukuncika ezinsimbi eziyigugu, kanye nezindleko zokukhiqiza eziphansi, ezinye izinkampani zengxenye yebhethri seziqalile ukuhlola enye indlela - ubuchwepheshe be-Zero Busbar (0BB).Kubikwa ukuthi lobu buchwepheshe bunganciphisa ukusetshenziswa kwesiliva ngaphezu kwe-10% futhi kwandise amandla engxenye eyodwa ngaphezu kwe-5W ngokunciphisa shading yangaphambili, okulingana nokukhulisa izinga elilodwa.
Ushintsho kwezobuchwepheshe luhlala luhambisana nokuthuthukiswa kwezinqubo nemishini.Phakathi kwazo, i-stringer njengento eyinhloko yokukhiqiza ingxenye ihlobene eduze nokuthuthukiswa kobuchwepheshe be-gridline.Ochwepheshe bezobuchwepheshe baveze ukuthi umsebenzi oyinhloko we-stringer ukushisela i-ribbon esitokisini ngokusebenzisa ukushisa okuphezulu okushisa ukuze kwakhiwe intambo, ephethe umgomo okabili "wokuxhuma" kanye "noxhumano lochungechunge", kanye nekhwalithi yayo yokushisela nokuthembeka ngokuqondile. kuthinte isivuno somhlangano kanye nezinkomba zamandla okukhiqiza.Kodwa-ke, ngokukhuphuka kobuchwepheshe be-Zero Busbar, izinqubo zendabuko zokushisela izinga lokushisa eliphezulu sezilokhu zinganele futhi zidinga ukushintshwa ngokushesha.
Kukulo mongo lapho kuvela khona ubuchwepheshe be-Little Cow IFC Direct Film Covering.Kuyaqondakala ukuthi i-Zero Busbar ifakwe ubuchwepheshe be-Little Cow IFC Direct Film Covering, obushintsha inqubo evamile yokushisela izintambo, yenza inqubo ye-cell stringing ibe lula, futhi yenze umugqa wokukhiqiza uthembeke futhi ukwazi ukulawuleka.
Okokuqala, lobu buchwepheshe abusebenzisi i-solder flux noma i-adhesive ekukhiqizeni, okuholela ekungcoleni nasekuvuneni okuphezulu kule nqubo.Iphinde igweme ukuphumula kwemishini okubangelwa ukugcinwa kwe-solder flux noma i-adhesive, ngaleyo ndlela iqinisekise isikhathi esiphezulu.
Okwesibili, ubuchwepheshe be-IFC buhambisa inqubo yokuxhuma i-metalization esigabeni sokubeka i-laminating, kuzuzwe ukushiselwa ngesikhathi esisodwa kwayo yonke ingxenye.Lokhu kuthuthukiswa kubangela ukufana kwezinga lokushisa lokushisela okungcono, kunciphisa amanani angenalutho, futhi kuthuthukise ikhwalithi yokushisela.Nakuba iwindi lokulungiswa kwezinga lokushisa le-laminator lincane kulesi sigaba, umphumela wokushisela ungaqinisekiswa ngokuthuthukisa impahla yefilimu ukuze ihambisane nezinga lokushisa elidingekayo le-welding.
Okwesithathu, njengoba isidingo semakethe sezingxenye zamandla aphezulu sikhula futhi ingxenye yamanani entengo yeselula yehla ezindlekweni zezingxenye, ukunciphisa ukuhlukaniswa kwama-intercell, noma ngisho nokusebenzisa izikhala ezingezinhle, kuba “inkambiso.”Ngenxa yalokho, izingxenye zosayizi ofanayo zingafinyelela amandla aphezulu okukhiphayo, okubalulekile ekwehliseni izindleko zengxenye ye-non-silicon kanye nokulondoloza izindleko zesistimu ye-BOS.Kubikwa ukuthi ubuchwepheshe be-IFC busebenzisa ukuxhumana okuguquguqukayo, futhi amaseli angapakishwa kufilimu, anciphise ngempumelelo isikhala phakathi kwama-intercell futhi azuze ukuqhekeka okunguziro ngaphansi kwesikhala esincane noma esingalungile.Ukwengeza, i-ribbon ye-welding ayidingi ukuba isicaba ngesikhathi senqubo yokukhiqiza, ukunciphisa ingozi yokuqhekeka kwamangqamuzana ngesikhathi se-lamination, ithuthukise ngokwengeziwe isivuno sokukhiqiza kanye nokuthembeka kwengxenye.
Okwesine, ubuchwepheshe be-IFC busebenzisa iribhoni yokushisela enezinga lokushisa eliphansi, behlisa izinga lokushisa lokuxhuma libe ngaphansi kuka-150.°C. Lokhu okusha kunciphisa kakhulu ukulimala kokucindezeleka okushisayo kumaseli, kunciphisa ngokuphumelelayo izingozi zokuqhekeka okufihliwe nokuphuka kwe-busbar ngemva kokuncipha kweseli, okwenza kube nobungane kakhulu kumaseli amancane.
Okokugcina, njengoba amaseli e-0BB engenawo imigqa yegridi eyinhloko, ukunemba kokuma kweribhoni yokushisela kuphansi uma kuqhathaniswa, okwenza ukukhiqizwa kwengxenye kube lula futhi kuphumelele kakhudlwana, nokuthuthukisa isivuno ngokwezinga elithile.Eqinisweni, ngemva kokukhipha imigqa yegridi eyinhloko, izingxenye ngokwazo zithandeka kakhulu ngobuhle futhi zithole ukuqashelwa kabanzi kumakhasimende ase-Europe nase-United States.
Kuhle ukusho ukuthi ubuchwepheshe be-Little Cow IFC Direct Film Covering buyixazulula kahle inkinga yokungqubuzana ngemva kokushisela amaseli e-XBC.Njengoba amaseli e-XBC anemigqa yegridi ohlangothini olulodwa kuphela, ukushisela kwentambo okunezinga eliphezulu lokushisa kungabangela ukungqubuzana okukhulu kwamaseli ngemva kokushisela.Kodwa-ke, i-IFC isebenzisa ubuchwepheshe bokumboza ifilimu obusezingeni eliphansi ukuze kuncishiswe ukucindezeleka okushisayo, okuholela ezintambo zeseli eziyisicaba futhi ezingasokiwe ngemva kokumbozwa kwefilimu, ukuthuthukisa kakhulu ikhwalithi yomkhiqizo nokuthembeka.
Kuyaqondakala ukuthi okwamanje, izinkampani eziningana ze-HJT ne-XBC zisebenzisa ubuchwepheshe be-0BB ezingxenyeni zabo, futhi izinkampani ezimbalwa ezihamba phambili ze-TOPCon nazo zibonise isithakazelo kulobu buchwepheshe.Kulindeleke ukuthi engxenyeni yesibili ka-2024, imikhiqizo eminingi ye-0BB izongena emakethe, ifake ubungqabavu obusha ekuthuthukisweni okunempilo nokusimeme kwemboni ye-photovoltaic.
