Kubudirira kukuru kweindasitiri yekubatana kwemagetsi muna 2023 kwave kuri kubudirira mukuderedza kushandiswa kwesirivha, zvichiratidza danho rakakosha mukuderedza mitengo uye kusimudzira kukwikwidzana kwechikamu ichi. Kubudirira kwekusimbisa mashandisirwo emagetsi ekubatana kwemagetsi muzviteshi zvemagetsi zvemumba chiratidzo chakanaka, kunyangwe purofiti yevagadziri isati yagadzikana zvizere.
Muna Chikumi 2024, cell yekutanga yeHJT+THL yakagadzirwa paTongwei's Global Innovation and R&D Center, nekubudirira mukubatanidza mhangura kwe gigawatt-scale kwakawanikwa panguva yekuyedza kwepilot. Simba repamusoro reDongfang Sunrise's heterojunction solar module rakasvika 767.38 Wp, ne module conversion efficiency ye24.70%, zvichiisa rekodhi itsva.
Pakati pekukwira kwemitengo yesirivha, matekinoroji akaita sesirivha yakaputirwa nemhangura, tekinoroji ye0BB, uye kudhinda stencil zvave kukosha zvikuru. Kufambira mberi uku hakungoderedzi kushandiswa kwesirivha mumabhatiri eHJT chete asiwo kunowedzera kushanda zvakanaka kwekushandura, zvichiwedzera kuvandudza kushanda zvakanaka kwetekinoroji yeHJT.
Kudiwa kwezvikamu zvemagetsi zvisina kuenzana kwakawedzera zvakanyanya, sezvinoratidzwa nekutengeswa kukuru kwemagetsi kubva kumafekitori emagetsi emuno uye kune dzimwe nyika. Nekutumira zvikamu kusvika 8-10 GW muna 2023, kudiwa kwemusika kwetekinoroji yemagetsi asina kuenzana kuri kuramba kuchikwira.
Muna 2024, kuvandudza kushanda zvakanaka kwe heterojunction kwave kukurumidzira kupfuura kuderedza mari, kunyanya sezvo tekinoroji ye TOPCon ichifambira mberi nekukurumidza. Tekinoroji ye heterojunction inofanira kuvandudza kuti iwane hutungamiriri hwemasimba hunosvika mawati makumi matatu.
Kuedza kuderedza mitengo kwachinja pfungwa kuenda pakuderedza kana kubvisa kushandiswa kwesirivha musirivha. Kunyangwe munzvimbo yekurasikirwa muindasitiri yese, tinotarisira kuti zvigadzirwa zvekubatana kwemarudzi akasiyana-siyana zviratidze purofiti, zvichiramba zvichichengetedza mukana wepamusoro uye wemutengo kupfuura zvigadzirwa zveTOPCon. Kutarisa pamusika kuriwo pakukura kwevagadziri vanotungamira, izvo zvichakanganisa kumhanya kwekudyara kwechikamu ichi.
Kuchinja kuviri kukuru kwakaitika munguva pfupi yapfuura: kudzikira kwemari yesirivha mupaste uye kudzikira kwemari yekugadzirisa paste yesirivha inodziya zvishoma. Kubudirira kwetekinoroji, kunyanya kubva kukambani inogadzira paste yekunze kwenyika KE, kwakaita kuti paste yesirivha ine 30% ibudirire, zvichideredza mitengo zvakanyanya. Pamusoro pezvo, kusanganisa tekinoroji ye0BB nepaste yesirivha ine 30% kwakapa tekinoroji ye heterojunction mukana wekushandisa sirivha shoma, zvichiita kuti ikwanise kuramba ichikura zvakanaka kana mitengo yesirivha yachinja.
Kunyangwe mitengo yesirivha iri kukwira zvichiwedzera mutengo wetekinoroji ye heterojunction, kukwikwidzana kwayo kukuru kuri mukushandiswa kwayo kwesirivha kushoma, zvichibatanidza mutengo wayo nekuchinja-chinja kwemitengo yesirivha. Zvisinei, kuvandudzwa kwesimba remagetsi kuchiri kukosha pakukura kwetekinoroji. Parizvino, tekinoroji ye heterojunction iri pamberi peTOPCon ne10 watts chete yezvigadzirwa zvikuru mu210 version.
Mumakota maviri kusvika matatu anotevera, kuvandudzwa kwesimba rekubatana kwemagetsi kunotarisirwa kupfuura TOPCon, zvichikonzerwa nekufambira mberi muPVD coating, secondary flocking, uye stencil printing technology. Izvi zvitsva zvinotarisirwa kuvandudza mashandiro emasero ne0.6-0.7%, zvichishandura kusvika kuma watts gumi nemashanu ekuvandudza simba mumamodules. Kudhinda mastencil chete kunotarisirwa kuwedzera 0.3% ekushanda zvakanaka nekuvandudza mapesta emhangura akaputirwa nesirivha.
Tekinoroji yemafirimu inopenya ndeimwe nzira inokosha. Sezvo vagadziri vakawanda vachipinda mumusika wemafirimu anopenya, mutengo/kushanda kwayo kwavandudzika, uye mitengo yadzikira, zvichiita kuti ive yakajairwa mukati megore. Pamwe chete nekuvandudzwa kwemabhatiri, mukana wesimba rekubatana kwemafirimu unotarisirwa kupfuura TOPCon unopfuura 4% kune 210 version uye anenge 30 watts kune 20 version panosvika kupera kwa2024.
Simba re2% kusvika ku5% mukuchinja kwakafanana kwe tekinoroji rinogona kukurudzira tekinoroji kubva pakubuda kuenda kune yakajairika. Musiyano we30-watts, zvichibva pamapatani ekare ekudzokorora tekinoroji, wakakosha. Semuenzaniso, mukana wesimba reTOPCon pamusoro pePERC wakawedzera kubva pa10-15 watts (2%) mukupera kwa2022 kusvika pa30 watts (5%) pakupera kwa2023, zvichiita kuti TOPCon ive tekinoroji inonyanya kukosha.
Simba re4% rinogona kukurudzira kuwedzera kwekubatana kwemagetsi. Zviziviso zveTOPCon zvazvino zvinoratidza kusununguka kune matekinoroji esirivha neakafukidzwa nemhangura, nekuvandudzwa kwekushanda zvakanaka kwekugadzira, mitengo isiri yesilicon, uye mari yekudyara mumidziyo. Kana kushanda zvakanaka uye kudzora mitengo yeGW line yazvino zvikazadzisa zvinotarisirwa, tekinoroji yekubatana kwemagetsi ichawana mabhenefiti akasimba emutengo uye kukura.
Kutarisa kunofanira kutarisa pakushambadzira kwetekinoroji yekudhinda mastencil, kuvandudza mashandiro, uye kushandiswa kwesimba revagadziri vakakosha vakaita seOrient Sunrise neChain Rise Technology. Kushanda kwemari kwevagadziri vakuru muchikamu chechitatu chegore kuchava chiratidzo chakakosha chekubudirira kwekushambadzira kwetekinoroji yekubatana.
