Kodi HJT solar cell ndi chiyani?

Kwa zaka zambiri, ukadaulo wa heterojunction (HJT) udanyalanyazidwa, koma wakula kwambiri m'zaka zaposachedwa, kuwonetsa kuthekera kwake kwenikweni. Ma module wamba a photovoltaic (PV) amawongolera zolepheretsa zomwe zafala kwambiri za ma module wamba a photovoltaic (HJT), monga kutsitsa kuyambiranso ndi kulimbikitsa magwiridwe antchito m'madera otentha.

Nkhaniyi ndi yanu ngati mukufuna kudziwa zambiri zaukadaulo wa HJT.

HJT Solar Cell Kutengera N-mtundu wa Silicon Wafer 

Monga ukadaulo wokhwima wa ma cell a solar, ukadaulo wa heterojunction watsimikiziridwa kuti umapereka magwiridwe antchito apamwamba, magwiridwe antchito abwino, komanso kulimba. 

Kapangidwe ka cell ya HJT ndiyothandiza kwambiri komanso sikuyenda pang'ono poyerekeza ndi ukadaulo wina wokonza ma cell.

HJT solar cell ndi cell yachilengedwe yapawiri, yokhala ndi mtundu wokhazikika wa solar.

Kodi HJT Solar Cell Imatanthauza Chiyani?

HJT ndi maselo a dzuwa a Hetero-Junction. Monga nthawi yolemba, HJT ndi wolowa m'malo mwa cell yotchuka ya solar ya PERC ndi matekinoloje ena monga PERT ndi TOPCON. Sanyo adayiyambitsa koyamba mu 1980s ndipo pambuyo pake idagulidwa ndi Panasonic mu 2010s.

Kupanga kumeneku kungapangitse kugwiritsa ntchito mizere yopangira ma cell a solar yomwe imagwiritsa ntchito ukadaulo wa PERC kukhala wosavuta chifukwa HJT ili ndi magawo ochepa kwambiri a magawo opangira ma cell komanso kutentha kocheperako kuposa PERC.

Chithunzi 1: PERC p-mtundu vs. HJT n-mtundu wa selo solar.

Chithunzi 1 chikuwonetsa momwe HJT imasiyanirana ndi mawonekedwe wamba a PERC. Zotsatira zake, njira zopangira ma topology awiriwa zimasiyana kwambiri. Mosiyana ndi n-PERT kapena TOPCON, yomwe ingasinthidwe kuchokera ku mizere yomwe ilipo ya PERC, HJT imafuna ndalama zambiri kuti igule zipangizo zatsopano isanayambe kupanga ndalama zambiri.

Kuphatikiza apo, monga ndi matekinoloje ambiri atsopano, ntchito yanthawi yayitali ya HJT ndi kukhazikika kwa kupanga zikufufuzidwa. Izi ndichifukwa chakukonza zovuta, kuphatikiza chidwi cha amorphous Si panjira zotentha kwambiri.

Kodi HJT Imagwira Ntchito Motani?

Pansi pa photovoltaic effect, heterojunction solar panels imagwira ntchito mofanana ndi ma modules a PV ochiritsira, kupatulapo kuti teknolojiyi imagwiritsa ntchito zigawo zitatu za zipangizo zoyamwitsa, kuphatikizapo mafilimu opyapyala ndi matekinoloje a photovoltaic. Mu chitsanzo ichi, tidzalumikiza katunduyo ku module, ndipo gawoli limasintha ma photon kukhala magetsi. Magetsi amenewa amayenda mu katundu.

Photon ikagunda cholumikizira cholumikizira cha PN, chimasangalatsa electron, yomwe imapangitsa kuti isamukire ku gulu la conduction ndikupanga awiri a electron-hole (eh).

The terminal pa P-doped wosanjikiza amatenga electron wokondwa, zomwe zimapangitsa magetsi kuyenda mu katundu.

Pambuyo podutsa katunduyo, electron imabwerera kumbuyo kwa selo ndikugwirizanitsa ndi dzenje, kubweretsa eh pair kuti itseke. Pamene ma modules amapanga mphamvu, izi zimachitika nthawi zonse.

Chodabwitsa chomwe chimadziwika kuti kuyambiranso kwapamwamba chimalepheretsa magwiridwe antchito a c-Si PV modules. Zinthu ziwirizi zimachitika pamwamba pa chinthu pamene electron ikusangalala. Kenako amatha kuyanjananso popanda electron kutengedwa ndikuyenda ngati mphamvu yamagetsi.

Kodi Maselo a Dzuwa a HJT Amagwira Bwino Komanso Ndi Odalirika?

Chifukwa cha hydrogenated intrinsic amorphous Si (a-Si:H mu chithunzi 1) yomwe ingapereke chilema ku mbali zonse za kumbuyo ndi kutsogolo kwa Si wafers, HJT imasonyeza bwino kwambiri ma cell a dzuwa (onse p-mtundu ndi n-mtundu polarity ).

ITO ngati maulumikizidwe owoneka bwino imathandizira kuyenda kwapano pomwe ikugwira ntchito ngati anti-reflection wosanjikiza kuti muzitha kujambula bwino. Njira ina yoyikira ITO pansi ndikuyigwiritsa ntchito potulutsa madzi otentha, zomwe zimapangitsa kuti amorphous wosanjikiza asawonekerenso. Izi zingapangitse kuchuluka kwa Si pamwamba kukhala kosavuta kwa zida zomwe zili pamenepo.

Ngakhale kuti ali ndi vuto lokonzekera komanso mtengo wake woyamba, HJT ikadali ukadaulo wotchuka. Poyerekeza ndi matekinoloje a TOPCON, PERT, ndi PERC, njirayi yawonetsa kuthekera kopanga > 23% mphamvu ya ma solar cell.

Makina a HJT Solar Panel?

makina a HJT solar Panel kupanga pafupifupi zofanana ndi zachilendo makina opanga ma solar, koma makina ochepa osiyana 

mwachitsanzo: HJT solar cell tabber stringer, HJT solar cell tester, ndi HJT solar panel laminator.

ndi makina opumula pafupifupi ofanana ndi abwinobwino, pangani mayankho athu amodzi omwe titha kupereka makina onse a mapanelo a dzuwa a HJT
