Pakadali pano, kukwezedwa kwa chandamale cha kaboni kwakhala mgwirizano wapadziko lonse lapansi, motsogozedwa ndi kukula kwachangu kwakufunika kwa PV, msika wapadziko lonse wa PV ukupitilizabe.Pampikisano wochulukirachulukira wamsika, matekinoloje amasinthidwa nthawi zonse ndikubwerezabwereza, kukula kwakukulu ndi zida za module yamphamvu zakhala njira yayikulu, kuphatikiza pazabwino, mtengo ndi zinthu zina, luso laukadaulo ndimwala wofunika kwambiri pakukula kwa mafakitale.

2023 Solar PV module innovation technology summit yomwe inachitikira pamodzi kuti awone za tsogolo latsopano la PV module development
Pa Januware 31, 2023, "2023 Solar PV Module Innovation Technology Summit", yoyendetsedwa ndi atolankhani odziwika padziko lonse lapansi a TaiyangNews, adachitika monga momwe adakonzera.Makampani ambiri otchuka a PV ochokera kwawo ndi kunja adasonkhana pa intaneti kuti akambirane za chitukuko chaukadaulo wa PV module.

Pamsonkhano waukadaulo waukadaulo, Xia Zhengyue, wamkulu wa gawo lazotukuka ku Tongwei, adaitanidwa kuti alankhule mawu akuti "Module Innovation kuchokera ku World's Largest PV Cell Manufacturer", ndikugawana zaukadaulo waposachedwa kwambiri wopangidwa ndi Tongwei.Kuphatikiza apo, TaiyangNews idachita kuyankhulana ndi Dr. Xing Guoqiang, Chief Technical Officer wa PV wa Tongwei, kuti adziwitse luso la Tongwei yopanga, ukadaulo wa R&D ndi mitu ina yofananira, ndikuyembekezera njira yamtsogolo yaukadaulo yazinthu zama module.

Kuwunika mbiri ya chitukuko cha makampani Tongwei PV, Tongwei wakhazikitsa 3 dziko loyamba kalasi PV luso R & D malo, umalimbana ndi luso malire, paokha anayamba makampani woyamba 1GW 210 TNC kupanga misa mzere, makampani woyamba lalikulu-kukula patsogolo metallization mzere mayeso. , komanso yomanga maselo atsopano ndi ma modules makampani ukadaulo woyendetsa woyendetsa mzere, etc., kupitiriza luso ndi jekeseni wamphamvu nyonga mu chitukuko makampani.

TOPCon ndi HJT njira ziwiri zotsogola muukadaulo waukadaulo wa TNC wofananira zimatsogolera chitukuko chatsopano
Pakalipano, maselo a PERC ali pafupi ndi malire owerengera bwino, ndipo gawo la maselo amtundu wa N lidzawonjezeka pang'onopang'ono.Poyankhulana mwapadera, Dr. Xing Guoqiang, Chief Technical Officer wa PV ya Tongwei, adanena kuti panopa, Tongwei akupita patsogolo mofanana ndi teknoloji ya TNC ndi THC.Poganizira kufunikira kotsatira kusintha komwe kukufunika pamsika, mawonekedwe a Tongwei apano apangidwa kuti azigwirizana ndi ma cell ndi ma module osiyanasiyana.

Ukadaulo wamtundu wa N ukulowa mwachangu.Mtengo, zokolola ndi kukhazikika kwa kutembenuka mtima ndizofunika kwambiri pakupanga misa yamtundu wa N.Nthawi yomweyo, zinthu zamtundu wa N ndizomwe zimakhudzidwa kwambiri pamakampani potengera mtengo ndi mtengo wogulitsa.Kudzera mosalekeza luso Mokweza ndi luso, panopa TNC mkulu-mwachangu gawo ndi 182-72 Baibulo awiri galasi Mwachitsanzo akhoza kuonjezera mphamvu ndi oposa 20W poyerekeza ndi chikhalidwe PERC mankhwala, ndipo ali pafupifupi 10% apamwamba bifacial mlingo kuposa PERC.Chifukwa chake, ma module apamwamba kwambiri a TNC ali kale azachuma ndipo adzakhala mbadwo watsopano wazinthu zomwe zimabweretsa kutulutsa mphamvu kwamphamvu, kudalirika kwambiri komanso kutsika kwamphamvu kwamagetsi.

Monga m'modzi mwa opanga otsogola kulowa mu gawo la HJT, kugwiritsa ntchito bwino kwambiri kwa R&D pama cell a Tongwei a HJT afika pa 25.67% (chiphaso cha ISFH).Komano, kugwiritsa ntchito bwino kwaukadaulo wolumikizana ndi mkuwa kwachepetsanso mtengo wazitsulo wa HJT.Pakalipano, teknoloji ya HJT yokhala ndi kutembenuka kwakukulu, kuchepa pang'ono ndi zabwino zina zomwe zimayembekezeredwa ndi msika, koma zochepa chifukwa cha kukwera mtengo kwa ndalama sizinayambe kuphulika.Chifukwa cha kuchulukirachulukira kwa ma cell komanso kupita patsogolo kwa kupanga zinthu zambiri, tsogolo laukadaulo la Tongwei la HJT likuwonekera mokulirakulira, pomwe "kuchepetsa ndalama ndi kukulitsa magwiridwe antchito" ndi manja onse awiri, HJT ibweretsa gawo lofunika kwambiri pakupanga zinthu. chitukuko chake.

Komanso, kuyambira 2020, Tongwei paokha anayamba "TNC" (Tongwei N-passivated kukhudzana cell) luso, ndipo panopa misa kupanga kutembenuka dzuwa la TNC maselo wadutsa 25.1%.Malinga ndi Xia Zhengyue, TNC cell ali mkulu mlingo bifacial, otsika attenuation, bwino kutentha koyenerera, kuyankha bwino kuwala otsika ndi ubwino zina ntchito, kudzipangira 182 kukula 72 mtundu theka-pepala gawo mphamvu mpaka 575W +, apamwamba kuposa PERC 20W + , 10% apamwamba bifacial mlingo, wafika makampani kutsogolera mlingo.Ma module awiri omwe amapangidwa ndi ukadaulo uwu ali ndi 3-5% yowonjezereka yamagetsi opangira mphamvu pa watt iliyonse kuposa ma module achikhalidwe a PERC, akukwaniritsadi kupindula kwakukulu kwamagetsi.

Ma module apamwamba a Tongwei amaganizira za ubwino wa zinthu zosiyanasiyana kuti akwaniritse ntchito zosiyanasiyana zomwe zimakhudza zochitika zonse.Mwachitsanzo, mankhwala a 182-72 omwe ali ndi ubwino wapamwamba amasankhidwa pazochitika zazikulu zamagetsi apansi;Chogulitsa cha 182-54 chokhala ndi chidwi chachikulu pazofunikira zakukula chitha kusankhidwa pazithunzi zapadenga.

Chaka cha 2022 chinali chaka chodabwitsa kwambiri pagawo la Tongwei.mu August, Tongwei analengeza mathamangitsidwe wa gawo ntchito masanjidwe ake ndi kukhazikitsa mofulumira ndondomeko kukula gawo, mokwanira kulimbikitsa ndondomeko ofukula kuphatikiza PV makampani ake;kuyambira pamenepo, yapambana motsatizana ndi ma module angapo abizinesi apakati aboma;mu Okutobala, Tongwei adalengeza kuti mndandanda wonse wa ma module a Terra adadutsa chiphaso cha carbon footprint chomwe chinaperekedwa ndi akuluakulu aku France Certisolis Mu Okutobala, Tongwei adalengeza kuti mndandanda wake wonse wama module a Terra omwe adasungidwa adalandira satifiketi ya carbon footprint ndi Certisolis. , boma la France;mu Novembala, ukadaulo wa Tongwei wodziyimira pawokha wa TNC wotsogola kwambiri adaperekedwa ngati imodzi mwaukadaulo khumi wapamwamba wa "Zero Carbon China" mu 2022;pambuyo pake, idasankhidwa kukhala Gawo 1 pamndandanda wa BNEF wa opanga ma module a PV Tier 1 padziko lonse lapansi mu kotala yachinayi ya 2022, kuwonetsa bwino msika kuzindikira kwakukulu kwa ma module a Tongwei ochita bwino kwambiri.Izi zikuwonetsa kuzindikira kwakukulu kwa msika kwa ma module apamwamba a Tongwei.

Malinga ndi Dr. Xing Guoqiang, mphamvu ya module ya Tongwei idzafika ku 14GW mu 2022, ndipo mphamvu yonse ya module ikuyembekezeka kufika 80GW kumapeto kwa 2023. Maziko olimba a chitukuko chofulumira cha bizinesi ya module.

Mpikisano ukachulukirachulukira, m'pamenenso mphamvu yaukadaulo yamphamvu;kukula kwa msika, ndikofunika kwambiri kumanga mpikisano, kuyang'anizana ndi msika womwe ukukula mofulumira, Tongwei akadali ndi chikhumbo chopita patsogolo ndi kutenga masitepe akuluakulu ndi okhazikika.M'tsogolomu, Tongwei ipitiliza kulimbitsa luso lake laukadaulo, kupititsa patsogolo kupikisana kwake, kupereka zinthu zotsogola komanso zapamwamba kwambiri kwa mabwenzi akumtunda ndi kumunsi kwa mtsinje, ndikuthandizira kukulitsa mphamvu zobiriwira ndikumanga chilengedwe chatsopano chamakampani okhazikika a PV.
