Abenzi beSeli abaPhambili bakuMdyarho wokufumana isihloko seRekhodi yokuSebenza kweSeli yeTopcon

• Ngokwengxelo yamva nje ye-TaiyangNews 'TOPCon Solar Technology, i-ISFH Imisela eyona TOPCon ukusebenza kakuhle kweeseli ngokufikelela kwi-26.1%, ngelixa amandla enkcazo aphezulu phakathi kwabo bonke kwi-28.7%
• Kubekho ugqatso phakathi kwabenzi beeseli ezingundoqo eziveliswa ngokwamashishini kwirekhodi yeseli ye-TOPCon; elona liphezulu langoku likwi-25.5% liphethwe yiTrina Solar
• I-Jolywood, inkokeli yorhwebo ye-TOPCon sele ifikelele ngaphezu kwe-24% yokusebenza kakuhle kwimveliso

Itekhnoloji ye-TOPCon inamandla okusebenza kwithiyori ephezulu kuma-28.7%, engaphezulu nangaphezulu kunaleyo ye-HJT's 27.5%. Nangona kunjalo, i-TOPCon engcono kakhulu efikeleleke ngoku ibe yi-ISFH kwi-26.1%, isengaphantsi kweyona ndlela ingcono ye-cell ye-HJT ye-26.63% ngu-Kaneka. La manani mabini aphezulu aphunyezwe ngokudibanisa uyilo lwe-IBC kunye neetekhnoloji ezifanelekileyo. I-ISFH ibeka irekhodi yayo ngokudibanisa isakhiwo sayo se-POLO sobunikazi kunye ne-IBC elungelelaniswe kwi-p-type base wafer. Kwiseli edibeneyo emacala amabini, iFraunhofer ISE ibhengeze irekhodi ye-26% esebenzayo kwiseli yayo ye-TOPCoRE, ulwakhiwo olwamkela ulwakhiwo lwangasemva kwisakhiwo se-TOPCon.

Umdyarho phakathi kwabavelisi be-PV abaqhelekileyo ngokwenene ube yinto enomdla, kunye nothotho lweerekhodi zokusebenza ezibhengezwe ukususela ekupheleni konyaka ophelileyo. U-Trina Solar, omnye wabamkeli bokuqala bobuchwephesha, usabambe owona msebenzi ugqwesileyo we-25.5%, kodwa wayengowokuqala phakathi kweenkampani eziphezulu ukubamba irekhodi lehlabathi elisebenzayo lama-24.58% ukusuka ngoMeyi 2019 ukuya kuJulayi ka-2020, ukuba yodlulwe yi-JinkoSolar's 24.79%. Akuzange kuthathe ixesha elide ukuba iJinkoSolar yaphule irekhodi layo, ibethe i-24.9% ekuqaleni kukaJanuwari 2021. ULONGi, umxhasi oqinileyo we-p-type PERC, ubhengeze ngo-Epreli 2021 ukuba waphule umqobo we-25% ngokufumana i-25.09% kwi-242.77 cm yayo ye-XNUMX cm.² Itekhnoloji yeseli ye-TOPcon ebizwa ngokuba yi-HPC. NgoJuni, malunga neenyanga ezi-2 kamva, iJinkoSolar yaphinda yafumana indawo ngokubhengeza ukusebenza kakuhle kwe-25.25%. Vala, kodwa akukho cigar - i-LONGi ibhengeze ngosuku olulandelayo ukuba iphumelele i-25.21%, iyancipha nge-0.04% nje, ngelixa i-avareji yokuqhuba i-pilot isebenza kwi-24.34%. Akukona nje ukuseta irekhodi, i-JinkoSolar iye yandisa imisebenzi yayo yokuthengisa kunye ne-TOPCon, ifikelela kwi-24.15% ukusebenza kakuhle kwimveliso yobuninzi, njengoko kubonisiwe kwinkomfa ye-TaiyangNews ebonakalayo kwiiModyuli zeSola eziPhezulu kakhulu. I-JA Solar yenye inkampani yenqanaba eliphezulu evavanya i-TOPCon. Inkampani kungoku nje ikwinqanaba lokulingwa ngobuchule obuphakathi obungaphezulu kwama-24%. Nangona kunjalo, kutsha nje (emva kokuba sipapashe ingxelo yethu ye-TOPCon), ngasekupheleni kuka-Matshi ka-2022, i-Trina Solar ibhengeze irekhodi layo lehlabathi lamva nje le-25.5%, eliye lelona liphezulu, kwaye lifunyenwe kwifomathi ye-G12 wafer.

Oko kwathiwa, i-Jolywood ibe yinkokeli xa kuziwa ekurhwebeni kwe-TOPCon kwaye mhlawumbi yinkampani kuphela eqhuba umgca wemveliso we-GW isikali se-TOPCon (nangona imbalwa eminye imigca yokulinga yenqanaba le-GW). I-Jolywood yaqala ngeteknoloji ye-n-type ye-PERT kwaye yaphucula ukusuka kwi-21.5% ukuya kwi-22% phakathi kwe-2016 kunye ne-2018. Ngokufanayo, iqalise imisebenzi yophuhliso ye-TOPCon kwi-2017 kunye nokusebenza kakuhle kokuqala kwe-21.8%, okwangoku imele i-23.8% ye-avareji kwimveliso yobuninzi. Ngeteknoloji ye-TOPCon 2.0 ephunyezwe kwisikali sokulinga, i-Jolywood sele iphumelele i-24.09% ye-avareji yokusebenza kakuhle kunye ne-97% yesivuno, ngelixa i-R & D esebenzayo ephunyeziweyo yi-24.5%. UGqr Du Zheren, uMlawuli weSeli yeR&D eJolywood, ngoMhla wesi-3 weTaiyangNews iNkomfa yeVirtual ngoBugcisa obuPhezulu beSolar Technologies ngo-2021 uthe ujonge ukuqhubela phambili nokuphucula umgangatho wobuchule bobuchwephesha be-TOPCon.

Ngeendlela zokuphucula ezifana nokuphumeza ii-emitters ezikhethiweyo, ukulungiswa kwee-anti-reflective coatings kunye ne-electrodes kunye nokunciphisa ubukhulu befilimu ye-polycrystalline ye-silicon, i-Jolywood ijolise ukubetha i-25% ngempumelelo ngesiqingatha sesibini se-2022. kufezwe ngo-0.2. Ukusetyenziswa kwee-wafers ezikumgangatho ophezulu kulindeleke ukuba kuzise umlenze wokugqibela wokuphucula, ukufikelela kwi-2024% ngo-25.52, ngokutsho kweJolywood. Inkampani iphinda icwangcise ukuqhubela phambili kwi-teknoloji yeseli yesizukulwana esilandelayo, esifana nesakhiwo se-tandem, esekelwe kwi-TOPCon, esetyenziswa njengesiseko kunye ne-perovskite phezulu, ukuphula umqobo we-2025% we-crystalline silicon cell.

Eli nqaku lifutshane lithatyathwe kwingxelo yethu yamva nje ye-TaiyangNews kwi-TOPCon Solar Technology, efumanekayo ukukhuphela mahala. ngokuchofoza iqhosha eliluhlaza ngezantsi.

INkomfa yeTaiyangNews kwiTekhnoloji yeSolar eSebenzayo, ngoSuku lwe-3, igxile kwi-TOPCon Cell. Ukuze ufunde ngakumbi malunga nenkomfa kwaye ujonge iintetho ezivela kwiinkokeli zemarike ze-varios cofa Apha
