Machina eHJT Solar Panel?

Kwemakore akawanda, tekinoroji yeheterojunction (HJT) yakafuratirwa, asi yakawana tsigiro mumakore achangopfuura, ichiratidza kugona kwayo chaiko. Ordinary photovoltaic (PV) modules inogadzirisa zvimwe zvezvakanyanya kuganhurirwa zveyakajairwa photovoltaic (HJT) modules, sekudzikisa recombination uye kuwedzera kushanda munzvimbo dzinopisa.

Ichi chinyorwa ndechenyu kana iwe uchida kudzidza zvakawanda nezve HJT tekinoroji.

HJT Solar Cell Yakavakirwa paN-mhando Silicon Wafer

Seyakakura solar cell tekinoroji, heterojunction tekinoroji yakaratidza kuendesa kugona kwepamusoro, kuita zvirinani, uye kusimba.

Iyo nzira yekugadzira yeHJT Cell inoshanda zvakanyanya uye inotora nhanho shoma kana ichienzaniswa nemamwe maseru ekugadzirisa tekinoroji.

HJT solar cell zvakare yakasikwa bifacial cell, ine yakanyanya kugadzikana solar cell color.

Chii Chinorevei HJT Solar Cell?

HJT inonzi Hetero-Junction solar masero. Sezvenguva yekunyora, HJT ndeye angango tsiva kune yakakurumbira PERC solar cell uye mamwe matekinoroji akaita sePERT uye TOPCON. Sanyo akatanga kuisuma kuma1980 uye yakazotengwa nePanasonic kuma2010.

Iyi dhizaini inogona kuita kuti kushandisa mitsara yekugadzira masero ezuva anoshandisa tekinoroji yePERC kuve nyore nekuti HJT ine nhamba diki yematanho ekugadzirisa masero uye tembiricha yakadzikira sero pane PERC.

Mufananidzo 1: PERC p-mhando vs. HJT n-mhando solar cell.

Mufananidzo 1 unoratidza kuti HJT inosiyana sei kubva kune yakajairwa PERC chimiro. Nekuda kweizvozvo, nzira dzekugadzira dzeaya maviri topology dzinosiyana zvakanyanya. Kusiyana ne-n-PERT kana TOPCON, iyo inogona kuchinjwa kubva kumiganhu yePERC iripo, HJT inoda mari yakawanda kutenga michina mitsva isati yatanga kuita mari yakawanda.

Uyezve, senge matekinoroji mazhinji matsva, kushanda kwenguva refu kweHJT uye kugadzikana kwekugadzira kuri kuongororwa. Izvi zvinokonzerwa nekugadzirisa nyaya, kusanganisira amorphous Si's sensitivity kune yakakwirira-tembiricha maitiro.

HJT Inoshanda Sei?

Pasi pe photovoltaic effect, heterojunction solar panels inoshanda zvakafanana kune yakajairwa PV modules, kunze kwekuti iyi tekinoroji inoshandisa matatu akaturikidzana ekutora zvinhu, kubatanidza yakaonda-firimu uye yakajairwa photovoltaic tekinoroji. Mumuenzaniso uyu, tichabatanidza mutoro kune module, uye module inoshandura mafotoni kuita magetsi. Magetsi aya anoyerera nemutoro.

Kana photon ikarova PN junction absorber, inofadza erekitironi, izvo zvinoita kuti iende kune conduction band uye kuita electron-hole (eh) pair.

Iyo terminal iri paP-doped layer inotora erekitironi inofara, izvo zvinoita kuti magetsi ayerere nemutoro.

Mushure mokupfuura nemutoro, erekitironi inodzokera kumashure kwesero uye inosanganazve negomba, ichiunza eh pair kusvika pakuvhara. Sezvo ma modules achigadzira simba, izvi zvinoitika nguva dzose.

Chiitiko chinozivikanwa sekubatanidzwazve kwepasi chinodzikamisa kushanda kweakajairwa c-Si PV modules. Zvinhu zviviri izvi zvinoitika pamusoro pechinhu kana elekitironi richifara. Vanogona kuzobatana zvakare pasina erekitironi inotorwa uye ichiyerera semagetsi.

Iyo HJT Solar Cell Inoshanda uye Yakavimbika here?

Nekuda kwekunakisisa hydrogenated intrinsic amorphous Si (a-Si:H muMufananidzo 1) iyo inogona kupa yakanakisa kuremara kune ese ari maviri kumashure nepamberi penzvimbo dzeSi wafers, HJT inoratidzira yakasarudzika solar cell kushanda zvakanaka (zvose p-mhando uye n-mhando polarity. )

ITO seyakajeka yekubatika inosimudzira kuyerera kwazvino panguva imwe chete ichishanda senge anti-reflection layer yekuvandudza kutorwa kwechiedza. Imwe nzira yekuisa ITO pasi ndeyekuzviita kuburikidza nekupuruzira pane yakaderera tembiricha, izvo zvinozochengeta iyo amorphous layer kubva pakugadzirisa zvakare. Izvi zvaizoita kuti iyo yakawanda Si yepamusoro isanyanya kupfuudza kune zvinhu zviri pairi.

Kunyangwe matambudziko ayo ekugadzirisa uye mutengo wekutanga unodhura, HJT inoramba iri tekinoroji yakakurumbira. Tichienzanisa neTOPCON, PERT, uye PERC tekinoroji, nzira iyi yakaratidza kugona kugadzira. > 23% solar cell kunyatsoshanda.
