Abenzi Bamaseli Abavamile Basemjahweni Wokuthola Isihloko Sokurekhoda Sokusebenza Kweseli Ye-Industrial Topcon

• Ngokombiko wakamuva we-TaiyangNews' TOPCon Solar Technology, i-ISFH Isetha ukusebenza kahle kwamaseli e-TOPCon ngokufinyelela ku-26.1%, kuyilapho amandla okucatshangelwa aphezulu kakhulu phakathi kwawo wonke ku-28.7%
• Kube khona umjaho phakathi kwabenzi beseli bokusakaza abaphambili berekhodi leseli le-TOPCon elikhiqizwe ngokwezimboni; ephezulu yamanje iku-25.5% ephethwe yi-Trina Solar
• I-Jolywood, umholi wezohwebo we-TOPCon usefinyelele ngaphezu kwe-24% ukusebenza kahle ekukhiqizeni

Ubuchwepheshe be-TOPCon inamandla aphakeme etiyetha angama-28.7%, angaphezulu ngisho kunalawo angama-27.5% e-HJT. Nokho, ukusebenza kahle kwe-TOPCon okungcono kakhulu okufinyelelwe kuze kube manje kube yi-ISFH ku-26.1%, kusengaphansi kokusebenza kahle kakhulu kweseli ye-HJT okungu-26.63% ngu-Kaneka. Lezi zibalo ezimbili eziphezulu empeleni zazuzwa ngokuhlanganisa izakhiwo ze-IBC nobuchwepheshe obufanele. I-ISFH isethe irekhodi layo ngokuhlanganisa isakhiwo sayo sokuphathelene se-POLO ne-IBC eguqulelwe ku-p-type base wafer. Ngeseli ethintwayo enezinhlangothi ezimbili, i-Fraunhofer ISE imemezele ukusebenza kahle okungama-26% kweseli yayo ye-TOPCoRE, isakhiwo esamukela ukwakheka kwenhlonhlo yangemuva esakhiweni se-TOPCon.

Umjaho phakathi kwabakhiqizi be-PV abajwayelekile ube yinto ethokozisayo, enochungechunge lwamarekhodi okusebenza amenyezelwe kusukela ekupheleni konyaka odlule. U-Trina Solar, ongomunye wabaqale ukusebenzisa ubuchwepheshe, usabambe isibalo sokusebenza okungcono kakhulu esingama-25.5%, kodwa futhi ube ngowokuqala phakathi kwezinkampani eziphezulu ukubamba irekhodi lomhlaba elisebenza kahle ngama-24.58% kusukela ngoMeyi 2019 kuze kube nguJulayi 2020, ukuze lidlulwe ngo-24.79% weJinkoSolar. Akuzange kuthathe isikhathi eside ukuthi iJinkoSolar yephule irekhodi layo, yashaya u-24.9% ekuqaleni kukaJanuwari 2021. ULONGi, umsekeli oqinile we-p-type PERC, umemezele ngo-April 2021 ukuthi yephule umgoqo ka-25% ngokuzuza u-25.09% ngo-242.77 cm wayo ongu-XNUMX cm.² I-TOPCon cell technology ebizwa nge-HPC. NgoJuni, cishe ezinyangeni ezi-2 kamuva, iJinkoSolar yaphinde yathola indawo ngokumemezela ukusebenza kahle okungama-25.25%. Vala, kodwa awukho ugwayi - i-LONGi yamemezela ngakusasa ukuthi ithole u-25.21%, yehla ngo-0.04% nje kuphela, kanti isilinganiso sokusebenza kahle komshayeli siku-24.34%. Hhayi nje ukusetha irekhodi, i-JinkoSolar ikhulise nemisebenzi yayo yezentengiselwano nge-TOPCon, yafinyelela ukusebenza kahle okungama-24.15% ekukhiqizeni ngobuningi, njengoba kuboniswe engqungqutheleni ebonakalayo ye-TaiyangNews yamaMojula Amandla Elanga Aphezulu Kakhulu. I-JA Solar ingenye inkampani esezingeni eliphezulu ebuye ihlole i-TOPCon. Njengamanje inkampani isesigabeni sokuhlola ukusebenza kahle okuphakathi kwama-24%. Kodwa-ke, muva nje (ngemuva kokushicilela umbiko wethu we-TOPCon), ngasekupheleni kukaMashi 2022, i-Trina Solar yamemezela irekhodi layo lomhlaba lakamuva lama-25.5%, okuyilona eliphakeme kakhulu kuze kube manje, futhi litholwa ngefomethi ye-G12 wafer.

Sekushiwo lokho, i-Jolywood ibilokhu ingumholi uma kukhulunywa ngohwebo kwe-TOPCon futhi mhlawumbe okuwukuphela kwenkampani esebenzisa ulayini wokukhiqiza we-GW esikalini we-TOPCon (yize kuneminye imigqa yokushayela yezinga le-GW embalwa). I-Jolywood iqale ngobuchwepheshe be-n-type PERT futhi yathuthukisa kusuka ku-21.5% kuya ku-22% phakathi kuka-2016 no-2018. Ngokuhambisanayo, iqale imisebenzi yokuthuthukisa i-TOPCon ngo-2017 ngokusebenza kahle kokuqala kwe-21.8%, okwamanje okumi ku-23.8% isilinganiso ekukhiqizeni ngobuningi. Ngobuchwepheshe bayo be-TOPCon 2.0 obusetshenziswe esikalini sokuhlola, i-Jolywood isivele izuze ukusebenza kahle kwesilinganiso esingu-24.09% ngesivuno esingu-97%, kuyilapho ukusebenza kahle kwe-R&D okuzuziwe kungu-24.5%. UDkt Du Zheren, uMqondisi we-Cell R&D e-Jolywood, ngoSuku lwesi-3 lwe-TaiyangNews Virtual Conference on High Efficiency Solar Technologies 2021 uthe uhlose ukuthuthukisa izinga lokusebenza kahle lobuchwepheshe babo be-TOPCon.

Ngezindlela zokuthuthukisa njengokusebenzisa ama-emitter akhethiwe, ukwenziwa kahle kwezingubo zokulwa nama-electrode nokunciphisa ukujiya kwefilimu ye-polycrystalline silicon, i-Jolywood ihlose ukushaya ukusebenza kahle okungama-25% ngesigamu sesibili sika-2022. Ukujwayela isakhiwo se-TOPCon futhi ngasohlangothini lwe-emitter, kodwa ngokukhetha ngaphansi kokuxhumana ne-polytelute yendawo, okulindeleke ukuba ithole i-polyteline% yendawo, okulindeleke ukuthi inkampani ithole i-polyteline. kuzofezwa ngo-0.2. Ukusebenzisa amawafa ekhwalithi ephezulu kulindeleke ukuthi kulethe umlenze wokugcina wokuthuthukiswa, kufinyelele ku-2024% ngo-25.52, ngokusho kweJolywood. Le nkampani futhi ihlela ukuqhubekela phambili kubuchwepheshe beselula besizukulwane esilandelayo, njengesakhiwo se-tandem, futhi esisekelwe ku-TOPCon, esetshenziswa njengesisekelo kanye ne-perovskite phezulu, ukuphula umgoqo we-2025% weseli ye-silicon ye-crystalline.

Lesi sihloko esifushane sithathwe embikweni wethu wakamuva we-TaiyangNews nge-TOPCon Solar Technology, etholakala ukuze ilandwe mahhala. ngokuchofoza inkinobho eluhlaza okwesibhakabhaka ngezansi.

I-TaiyangNews Conference on High Efficiency Solar Technologies, ngoSuku 3, igxile ku-TOPCon Cell. Ukuze ufunde kabanzi mayelana nengqungquthela futhi ubuke izethulo ezivela kubaholi bemakethe ye-varios chofoza lapha
