Njengamanje, ukugqugquzelwa kwethagethi ye-carbon neutral sekuyisivumelwano somhlaba wonke, esiqhutshwa ukukhula okusheshayo kwesidingo esifakiwe se-PV, imboni ye-PV yomhlaba wonke iyaqhubeka nokuthuthuka.Emncintiswaneni wezimakethe okhulayo, ubuchwepheshe buvuselelwa njalo futhi buphindwaphindwa, usayizi omkhulu kanye nemikhiqizo yemojula yamandla aphezulu isiphenduke inkambiso enkulu, ngaphezu kwekhwalithi, izindleko nezinye izici, ukusungulwa kwezobuchwepheshe nakho kuyitshe legumbi elibalulekile lokuthuthukiswa kwezimboni.

Ingqungquthela yobuchwepheshe be-Solar PV ye-2023 yokusungula ubuchwepheshe obanjelwe ndawonye ukuze kubhekwe ikusasa elisha lokuthuthukiswa kwemojula ye-PV
NgoJanuwari 31, 2023, “i-2023 Solar PV Module Innovation Technology Summit”, eyayisingathwe abezindaba abadumile emhlabeni wonke i-TaiyangNews, yabanjwa njengoba kwakuhleliwe.Izinkampani eziningi ezidumile ze-PV ezivela ekhaya nakwamanye amazwe zahlangana ku-inthanethi ukuze zidingide umkhuba wokuthuthukiswa kobuchwepheshe bokusungula imojula ye-PV.

Kusemina yokusungula ubuchwepheshe, u-Xia Zhengyue, inhloko yokuthuthukiswa komkhiqizo wemojula ye-Tongwei, wamenywa ukuthi ethule inkulumo enesihloko esithi “Module Innovation evela kumkhiqizi wamaseli we-PV Omkhulu Kunawo Wonke Emhlabeni”, ukwabelana ngenqubekelaphambili yakamuva yobuchwepheshe bemojuli ethuthukiswe ngu-Tongwei.Ngaphezu kwalokho, i-TaiyangNews yenze ingxoxo noDkt. Xing Guoqiang, Isikhulu Esiyinhloko Sezobuchwepheshe se-PV yase-Tongwei, ukuze ethule umthamo wokukhiqiza we-Tongwei, i-R&D yobuchwepheshe nezinye izihloko ezihlobene, kanye nokubheka phambili kumzila wesikhathi esizayo wokuthuthukiswa kobuchwepheshe bemikhiqizo yamamojula.

Ukubukeza umlando wokuthuthukiswa kwemboni ye-Tongwei PV, i-Tongwei isungule izikhungo ezingu-3 ze-PV ubuchwepheshe be-R&D kazwelonke yokuqala, okuhloswe ngazo emngceleni wobuchwepheshe, ithuthukiswe ngokuzimela umugqa wokuqala wokukhiqiza we-1GW 210 TNC wemboni, umugqa wokuqala wokuhlola we-metalization we-metalization wokuqala omkhulu. , kanye nokwakhiwa kwamaseli amasha namamojula ulayini wokuhlola wemboni yezobuchwepheshe obujwayelekile, njll., ukuze kuqhutshekwe nokuqanjwa kabusha nokufaka ubungqabavu obunamandla ekuthuthukisweni kwemboni.

I-TOPCon kanye ne-HJT ehamba phambili yomzila okabili ekusungulweni kobuchwepheshe be-TNC okufanayo kuholela ekuthuthukisweni okusha
Okwamanje, amaseli e-PERC aseduze nokusebenza kahle komkhawulo wethiyori, futhi ingxenye yamaseli ohlobo lwe-N izokhula kancane kancane.Engxoxweni ekhethekile, uDkt. Xing Guoqiang, oyiChief Technical Officer we-PV yase-Tongwei, uveze ukuthi okwamanje, u-Tongwei uthuthuka ngokuhambisana nobuchwepheshe be-TNC kanye ne-THC.Uma kucatshangelwa isidingo esilandelayo sokuzivumelanisa ngokushesha nesidingo semakethe esishintshayo, ukwakheka kwemojula yemojula yamanje ye-Tongwei yakhelwe ukuthi ihambisane nobuchwepheshe obuhlukahlukene beseli kanye nemojula.

Ubuchwepheshe bohlobo lwe-N bungena ngokushesha.Izindleko, isivuno kanye nokuzinza kokusebenza kahle kokuguqulwa yizihluthulelo zokukhiqizwa kwenqwaba yohlobo lwe-N.Ngasikhathi sinye, imikhiqizo yohlobo lwe-N nayo iyiphuzu elikhathazeke kakhulu embonini ngokwezindleko namanani okuthengisa.Ngokuthuthukiswa okuqhubekayo kobuchwepheshe kanye nokusungula izinto ezintsha, imojula yamanje ye-TNC esebenza kahle kakhulu enenguqulo eyingilazi ephindwe kabili engu-182-72 njengesibonelo ingakhuphula amandla angaphezu kuka-20W uma iqhathaniswa nemikhiqizo yendabuko ye-PERC, futhi inezinga elicishe libe ngu-10% eliphakeme le-bifacial kune-PERC.Ngakho-ke, amamojula asebenza kahle kakhulu e-TNC asevele ayonga futhi azoba isizukulwane esisha semikhiqizo eletha ukukhiqizwa kwamandla aphezulu, ukwethembeka okuphezulu kanye nokuncishiswa okuphansi kwezitshalo zikagesi.

Njengomunye wabakhiqizi bokuqala abahamba phambili ukungena emkhakheni we-HJT, ukusebenza kahle okuphezulu kwe-R&D kwamaseli e-HJT amanje akwa-Tongwei sekufinyelele ku-25.67% (isitifiketi se-ISFH).Ngakolunye uhlangothi, ukusetshenziswa ngempumelelo kobuchwepheshe bokuxhumanisa ithusi nakho kunciphise kakhulu izindleko ze-metalization ze-HJT.Njengamanje, ubuchwepheshe be-HJT obusebenza kahle kakhulu ekuguquleni, ukuncipha kancane nezinye izinzuzo ezinikezwa imakethe okulindeleke kakhulu, kodwa okukhawulwe yizindleko eziphakeme zokutshala imali abukangenisi ukuqhuma.Ngokukhula okuphawulekayo kokusebenza kahle kwamaseli kanye nokuthuthuka kwezimo zokukhiqiza ngobuningi, unqenqema oluphambili lwesakhiwo sobuchwepheshe be-HJT ye-Tongwei luya ngokuya lubonakala, kuyilapho “ukunciphisa izindleko nokwandisa ukusebenza kahle” ngezandla zombili, i-HJT izoletha ingqopha-mlando ukuthuthukiswa kwayo.

Ngaphezu kwalokho, kusukela ngo-2020, i-Tongwei ithuthukise ngokuzimela ubuchwepheshe be-"TNC" (i-Tongwei N-passivated contact cell) kanye nokusebenza kahle kokuguqulwa kokukhiqiza okukhulu kwamaseli e-TNC kudlule ama-25.1%.Ngokuka-Xia Zhengyue, iseli ye-TNC inezinga eliphezulu le-bifacial, i-attenuation ephansi, i-coefficient yokushisa engcono, impendulo enhle ekukhanyeni okuphansi nezinye izinzuzo zokusebenza, inguqulo ezenzele yona engu-182 usayizi 72 uhlobo lwengxenye yeshidi amandla afinyelela ku-575W+, aphezulu kune-PERC 20W+ , izinga eliphezulu elingu-10% le-bifacial, selifinyelele izinga elihamba phambili embonini.Amamojula akabili akhiqizwe ngalobu buchwepheshe anenzuzo yokuphehla amandla engu-3-5% ephakeme nge-watt ngayinye kunamamojula e-PERC avamile, azuza ngempela inzuzo ephezulu yokuphehla amandla.

Amamojula we-Tongwei asebenza kahle kakhulu acabangela izinzuzo zemikhiqizo ehlukene ukuze afinyelele inhlobonhlobo yezinhlelo zokusebenza ezihlanganisa zonke izimo.Isibonelo, umkhiqizo we-182-72 onezinzuzo zesistimu ephezulu ukhethwa izimo ezinkulu zezitshalo zamandla omhlaba;umkhiqizo we-182-54 onokuzwela okuphezulu kwezidingo zesayizi ungakhethelwa izimo zokuhlala eziphezu kophahla.

Ngezinzuzo zomholi we-silicon cell ophindwe kabili, inqubo ka-Tongwei yokuhlanganisa mpo iqhubeka ngokugcwele
Unyaka ka-2022 bekuwunyaka ongavamile engxenyeni yemojuli kaTongwei.ngo-Agasti, i-Tongwei yamemezela ukusheshisa kwesakhiwo sebhizinisi lemojula yayo kanye nokuqaliswa okusheshayo kohlelo lwayo lokunwetshwa kwamamojula, ikhuthaza ngokugcwele inqubo yokuhlanganisa eqondile yemboni yayo ye-PV;kusukela lapho, iphumelele ngokulandelana inqwaba yamaphrojekthi okubhida amamojula ezinkampani zikahulumeni ezimaphakathi;ngo-Okthoba, u-Tongwei umemezele ukuthi lonke uchungechunge lwamamojula ahlanganisiwe we-Terra asephase isitifiketi se-carbon footprint esinikezwe isikhulu sase-France i-Certisolis Ngo-Okthoba, u-Tongwei wamemezela ukuthi uchungechunge lwayo olugcwele lwamamojula ahlanganisiwe we-Terra anikezwe isitifiketi se-carbon footprint yi-Certisol. , isikhulu saseFrance;ngoNovemba, ubuchwepheshe be-TNC obusebenza kahle kakhulu be-TNC baklonyeliswa njengobunye bobuchwepheshe obuphezulu obuyishumi obusha be-“Zero Carbon China” ngo-2022;ngemuva kwalokho, yakleliswa njengeTier 1 ohlwini lwe-BNEF lwabakhiqizi bemojula ye-PV Tier 1 yomhlaba wonke engxenyeni yesine ka-2022, okubonisa ngokugcwele ukuqashelwa okuphezulu kwemakethe kwamamojula asebenza kahle kakhulu e-Tongwei.Lokhu kukhombisa ukuqashelwa okuphezulu kwemakethe kwamamojula we-Tongwei asebenza kahle kakhulu.

NgokukaDkt. Xing Guoqiang, umthamo wemojula ye-Tongwei uzofinyelela ku-14GW ngo-2022, futhi umthamo wemojula usuwonke kulindeleke ukuthi ufinyelele ku-80GW ekupheleni kuka-2023. Isisekelo esiqinile sokuthuthukiswa okusheshayo kwebhizinisi lemojuli.

Lapho ukuncintisana kushube, kulapho umfutho wokusungula unamandla;uma sikhulu isikali semakethe, kubaluleke kakhulu ukwakhiwa kokuncintisana, ebhekene nemakethe ekhula ngokushesha, uTongwei usenokuzimisela ukuya phambili futhi athathe izinyathelo ezinkulu neziqinile.Ngokuzayo, i-Tongwei izoqhubeka nokuhlanganisa amandla ayo okuqanjwa kabusha kwezobuchwepheshe, ithuthukise futhi ukuncintisana kwayo yonke, ihlinzeke ngemikhiqizo esebenza kahle nesezingeni eliphezulu kubalingani abakhuphuka nomfula kanye nabangezansi komfula, futhi isize ukuthuthukiswa kwamandla aluhlaza futhi yakhe imvelo entsha yemboni ye-PV esimeme.
