Ngokuthuthuka kwezobuchwepheshe kanye nokunciphisa amanani entengo yomkhiqizo, isikali semakethe ye-Global Photovoltaic sizoqhubeka nokukhula ngokushesha, futhi ingxenye ye-N-Type Products emikhakheni ehlukahlukene iyanda njalo. Izikhungo eziningi zibikezela ukuthi ngo-2024, umthamo osanda kufakwa we-Global Photovoltaic Power Generation Generation kulindeleke ukuthi weqe ama-500gw (DC), futhi ingxenye yezakhi zebhethri ye-N-Type izoqhubeka ukukhulisa ikota ngayinye, nesabelo esilindelekile sangezinkulungwane ezingama-85% ngo ukuphela konyaka.
Kungani imikhiqizo ye-n-hlobo ingaqedela ama-technological adsly ngokushesha? Abahlaziyi bakwaSBI Consultancy bakhomba ukuthi, ngakolunye uhlangothi, izinsiza zomhlaba ziya ngokuya zinqabile, zidinga ukukhiqizwa kukagesi ohlanzekile ngokwengeziwe ezindaweni ezilinganiselwe; Ngakolunye uhlangothi, ngenkathi amandla engxenye yebhethri ye-N-Type banda ngokushesha, umehluko wentengo ngemikhiqizo ye-P-Type mncane kancane kancane. Ngokombono wamanani entengo avela kumabhizinisi amaningana aphakathi, umehluko wentengo phakathi kwezingxenye ze-NP zenkampani efanayo ngamasenti ama-3-5 kuphela / W, uqokomisa ukusebenza kwezindleko.
Ochwepheshe bezobuchwepheshe bakholelwa ukuthi ukwehla okuqhubekayo kokutshalwa kwezimali, ukuthuthukiswa okuqinile ekusebenzeni komkhiqizo, futhi ukuhlinzekelwa kwamakethe owanele kusho ukuthi inani lentengo le-N-Type Product lizoqhubeka nokuncipha, futhi kusekhona indlela ende yokunciphisa izindleko nokukhulisa ukusebenza kahle kanye nokwandisa kahle izindleko . Ngasikhathi sinye, bagcizelela ukuthi ubuchwepheshe be-Zero Busbar (0BB) Technology, njengendlela ephumelelayo ephumelelayo yokunciphisa izindleko nokwandisa ukusebenza kahle, kuzodlala indima ebaluleke kakhulu emakethe ye-Photovoltaic yesikhathi esizayo.
Uma ubheka umlando wezinguquko kuma-gridlines weseli, amaseli okuqala e-PhotoVoltaic kuphela ane-gridlines eyi-1-2 eyinhloko. Kamuva, ama-gridlines amane aphambili nama-gridines amahlanu aholele kancane kancane inkambo yemboni. Kusukela engxenyeni yesibili ka-2017, ubuchwepheshe obuningi beBusbar (MBB) buqala ukusetshenziswa, kwathi kamuva kwathuthukiswa ku-Super Busbar (SMBB). Ngomklamo wama-gridines ayi-16 asemqoka, indlela yokudluliselwa kwamanje kuma-gridlines asemqoka incishisiwe, yandisa amandla okukhishwa kwemali ephelele yezakhi, wehlise izinga lokushisa elisebenzayo, futhi kuholele ekutheni ugesi osebenzayo.
Njengoba amaphrojekthi amaningi futhi amaningi aqala ukusebenzisa ukusetshenziswa kwesiliva, ukuze anciphise ukuncishiswa kwesiliva, futhi anciphise ukuncika kwezinsimbi eziyigugu, kanye nezindleko eziphansi zokukhiqiza, ezinye izinkampani ze-battery zebhethri sebeqalile ukuhlola enye indlela - zero burbar (0BB) ubuchwepheshe. Kubikwa ukuthi lobu buchwepheshe bunganciphisa ukusetshenziswa kwesiliva ngaphezulu kwama-10% futhi bandise amandla engxenye eyodwa nangaphezulu kwe-5W ngokunciphisa i-Front-Side Shading, okulingana nokukhulisa izinga elilodwa.
Ushintsho kubuchwepheshe luhambisana nokuthuthuka kwezinqubo nemishini. Phakathi kwazo, i-stringer njengemishini eyisisekelo yokukhiqiza ingxenye ehlobene kakhulu nentuthuko yobuchwepheshe be-gridline. Ochwepheshe bezobuchwepheshe baveze ukuthi umsebenzi oyinhloko we-Steringer ukuwela iribhoni liye esitokisini ngokushisa okushisa okuphezulu ukuze wakhe intambo, uthwele ikhwalithi ephimbili "yokuxhumana" kanye nekhwalithi yayo ye-welding thinta isivuno se-workshop kanye nezinkomba zamandla okukhiqiza. Kodwa-ke, ngokukhuphuka kobuchwepheshe be-zero busbar technology, izinqubo zokushisa izimoto eziphakeme zendabuko ziye zanda futhi zidinga ukushintshwa.
Kukulesi simo sokuthi inkomo encane ye-IFC eqondile yefilimu emboza ngayo. Kuyaqondakala ukuthi i-zero burbar ifakwe i-Little Cow IFC Direct Film Technology, eshintsha inqubo ye-Welding ye-Welding ye-String, yenza lula inqubo yokwenziwa kwenhlanganisela yeseli, futhi yenza umugqa wokukhiqiza uthembeke futhi ulawuleke.
Okokuqala, lobu buchwepheshe abusebenzisi i-solder flux noma ukunamathela ekukhiqizeni, okuholela ekungcoleni kanye nesivuno esikhulu kule nqubo. Ibuye igweme isikhathi sokuphumula semishini esibangelwa ukugcinwa kwe-solder flux noma ukunamathela, ngaleyo ndlela iqinisekise isikhathi esiphakeme.
Okwesibili, ubuchwepheshe be-IFC bushukumisela inqubo yokuxhuma insimbi yensimbi esigabeni se-laming, ukufeza ukufudumala ngasikhathi sinye kwalo lonke isakhi. Lo ntuthuko imiphumela ekuhlolweni okungcono kwe-welding lokushisa, kunciphisa amanani angenalutho, futhi kuthuthukise ikhwalithi ye-welding. Yize iwindi lokulungiswa kwezinga lokushisa le-laminator lincibilika ngalesi sigaba, umphumela we-welding ungaqinisekiswa ngokwenza kahle izinto zefilimu ukufanisa izinga lokushisa elidingekayo le-welding.
Okwesithathu, njengoba ukufunwa kwemakethe kwezinto ezinamandla amakhulu kukhula futhi ingxenye yamanani entengo yeseli incipha ezindlekweni zezakhi, ukunciphisa ukuhlukaniswa kwezikhala, noma ukusebenzisa izikhala ezingezinhle, iba "yinkambiso." Ngenxa yalokho, izingxenye zosayizi ofanayo zingafinyelela amandla aphezulu okukhipha, okubalulekile ekunciphiseni izindleko ezingezona ze-silicon kanye nezindleko zokulungisa ama-bos. Kubikwa ukuthi ubuchwepheshe be-IFC busebenzisa ukuxhumana okuguquguqukayo, futhi amaseli angafakwa kwifilimu, anciphise ngempumelelo ukuhlukaniswa kwe-Intercell nokuthola ukuqhekeka okufihliwe kwe-zero ngaphansi kwesikhala esincane noma esibi. Ngaphezu kwalokho, iribhoni elishisayo alidingi ukugcwala ngesikhathi sokukhiqiza, ukunciphisa ubungozi bokuqhekeka kweseli ngesikhathi sokukhanya, ngcono ukuthuthukisa ukukhiqiza kanye nokwethembeka kokukhiqiza.
Okwesine, Ubuchwepheshe be-IFC busebenzisa iribhoni eliphansi lokushisa ukushisa, ukunciphisa izinga lokushisa lokuxhumana kuya ngaphansi kuka-150°C. Lokhu okusha kunciphisa kakhulu ukulimala kwengcindezi eshisayo kumaseli, kunciphise ngempumelelo ubungozi bokuqhekeka okufihliwe kanye nokuqhekeka kwebhasi ngemuva kokuncipha kweseli, okwenza kube nobungane kakhulu kumaseli amancanyana.
Ekugcineni, njengoba amaseli we-0BB anawo ama-gridlines aphambili, ukunemba kwe-welding ribbon kuphansi, okwenza ukukhiqizwa okungcono kwengxenye futhi kusebenze kahle, kanye nokwenza ngcono isivuno ngezinga elithile. Eqinisweni, ngemuva kokususa ama-gridlines angaphambili, izakhi ngokwazo zijabulisa kakhulu futhi zithole ukuqashelwa okubanzi kumakhasimende eYurophu nase-United States.
Kuyafaneleka ukusho ukuthi inkomo encane yenkomo i-IFC eqondile yefilimu emboza ubuchwepheshe ixazulula ngokuphelele inkinga yokufaka amaseli we-welding XBC. Njengoba amaseli we-XBC anama-grideline kuphela ohlangothini olulodwa, i-welding evamile yokushisa i-welding ingadala ukwehla okukhulu kwamaseli ngemuva kokushiswa. Kodwa-ke, i-IFC isebenzisa ubuchwepheshe obuphansi bokushisa ifilimu ukunciphisa ukucindezelwa okushisayo, okuholele ekutheni izintambo zeseli ezifuywayo nezingezinhle ngemuva kokumboza ifilimu, ithuthukisa kakhulu ikhwalithi yomkhiqizo.
Kuyaqondakala njengamanje, izinkampani eziningana ze-HJT ne-XBC zisebenzisa ubuchwepheshe be-0BB ezingxenyeni zabo, futhi izinkampani ezimbalwa eziholayo zeTopcon ziveze nentshisekelo kulobu buchwepheshe. Kulindeleke ukuthi engxenyeni yesibili ka-2024, imikhiqizo eminingi ye-0BB izongena emakethe, ifaka ubungqabavu obusha ekuthuthukisweni okunempilo nokuzinzile kwemboni ye-Photovoltaic.
