Mumakore achangopfuura, nekuvandudzwa uye kushandiswa kwematekinoroji matsva, maitiro matsva uye zvimiro zvitsva zve photovoltaic masero, photovoltaic cell industry yakagadzira nokukurumidza. Seyakakosha tekinoroji inotsigira kuvandudzwa kwesimba idzva uye smart grids, n-mhando masero ave nzvimbo inopisa mukusimudzira maindasitiri epasirese.
Nekuti iyo n-mhando tunneling oxide layer passivation yekubata photovoltaic cell (inozonzi "n-type TOPCon cell") ine mukana wekuita basa rekuvandudza zvakanyanya kushanda zvakanaka kana ichienzaniswa neyakajairwa photovoltaic masero, nekuwedzera kwemutengo unodzoreka uye wakakura shanduko yemidziyo, iyo n-mhando TOPCon sero Kuwedzera kuwedzera kwesimba rekugadzira mudzimba rave iro guru rekusimudzira danho repamusoro-kushanda photovoltaic masero.
Kumisikidzwa kwen-mhando TOPCon mabhatiri anotarisana nematambudziko sekutadza kuvhara zviyero zvazvino uye kukosha kwekuvandudza kushanda kwemazinga. Iri bepa richaita tsvakiridzo uye ongororo pamusoro pekumisikidzwa kwen-mhando TOPCon mabhatiri, uye kupa mazano ekumisikidza.Mamiriro ekuvandudza yen-mhando TOPCon cell tekinorojiChimiro chep-mhando silicon base zvinhu zvinoshandiswa mune zvakajairwa photovoltaic masero ndeye n + pp +, iyo inogashira mwenje nzvimbo ndeye n + pamusoro, uye phosphorus diffusion inoshandiswa kugadzira emitter.Kune mhando mbiri huru dzehomojunction photovoltaic cell zvimiro zve n-mhando silicon base zvinhu, imwe n+np+, uye imwe iri p+nn+.Kana ichienzaniswa ne-p-mhando silicon, n-mhando silicon ine zvirinani vashoma mutakuri hupenyu hwese, yakaderera attenuation, uye yakakura kugona kugona.Iyo n-mhando yakapetwa kaviri-sero yakagadzirwa ne-n-mhando silicon ine zvakanakira kushanda kwepamusoro, yakanaka yakaderera mwenje mhinduro, yakaderera tembiricha coefficient, uye mamwe maviri-mativi emagetsi ekugadzira.Sezvo zvinodikanwa zveindasitiri zvephotoelectric kutendeuka kushanda zvakanaka kwephotovoltaic masero zvichiramba zvichiwedzera, n-mhando yepamusoro-soro photovoltaic maseru akadai TOPCon, HJT, uye IBC zvishoma nezvishoma inotora musika unotevera.Zvinoenderana ne2021 International Photovoltaic Roadmap (ITRPV) yepasi rose photovoltaic indasitiri tekinoroji uye fungidziro yemusika, n-mhando masero anomiririra tekinoroji yeramangwana uye kutungamira kwemusika kutungamira kwemafotovoltaic maseru kumba nekune dzimwe nyika.Pakati penzira dzehunyanzvi dzemhando nhatu dze-n-mhando mabhatiri, n-mhando TOPCon mabhatiri ave nzira yetekinoroji ine hukuru hukuru hwemaindasitiri nekuda kwekunakirwa kwavo kwehuwandu hwekushandisa kwemidziyo iripo uye nepamusoro pekushandura.
Parizvino, n-mhando TOPCon mabhatiri muindastiri anowanzo gadzirirwa zvichibva paLPCVD (yakaderera-pressure vapor-phase kemikari deposition) tekinoroji, ine maitiro mazhinji, kushanda nesimba uye goho zvinorambidzwa, uye michina inovimba nekunze. Inoda kuvandudzwa. Iyo yakakura-yakakura kugadzirwa kwen-mhando TOPCon maseru anotarisana nematambudziko ehunyanzvi akadai semutengo wepamusoro wekugadzira, maitiro akaomarara, chiyero chegoho rakaderera, uye kusakwana kwekushandura.Iyo indasitiri yakaedza kwakawanda kuvandudza tekinoroji yen-mhando TOPCon maseru. Pakati pavo, iyo in-situ doped polysilicon layer tekinoroji inoiswa mune imwechete-maitiro deposition ye tunneling oxide layer uye doped polysilicon (n + -polySi) layer isina kuputira plating;Iyo simbi electrode yen-mhando TOPCon bhatiri inogadzirirwa nekushandisa tekinoroji nyowani yekusanganisa aluminium paste uye sirivheri paste, iyo inoderedza mutengo uye inovandudza kupikisa kubata; inotora iyo yekumberi yakasarudzika emitter chimiro uye kumashure akawanda-layer tunneling passivation yekubata chimiro tekinoroji.Uku kukwidziridzwa kwetekinoroji uye mashandiro ekuita zvakapa mamwe mipiro mukusimudzirwa kwen-mhando TOPCon maseru.Tsvagiridzo yekumira kwen-mhando TOPCon bhatiriPane mimwe misiyano yehunyanzvi pakati pen-mhando TOPCon maseru uye akajairwa p-mhando photovoltaic masero, uye mutongo wemasero ephotovoltaic pamusika unoenderana neyakajairwa bhatiri zviyero, uye hapana chakajeka chinodiwa chen-mhando photovoltaic masero. .I-n-type TOPCon cell ine maitiro ekuderedza attenuation, kutsika kwekushisa kwepasi, kushanda kwepamusoro, high bifacial coefficient, high opening voltage, etc. Yakasiyana neyakajairwa photovoltaic masero maererano nemitemo.
Ichi chikamu chinotanga kubva pakutemerwa kweakajairwa zviratidzo zven-mhando TOPCon bhatiri, ita inowirirana verification yakatenderedza curvature, electrode tensile simba, kuvimbika, uye yekutanga chiedza-induced attenuation performance, uye kurukurai mhinduro dzechokwadi.Kutsunga kwezviratidzo zvakajairikaConventional photovoltaic masero akavakirwa pane chigadzirwa standard GB/T29195-2012 "General Specifications for Ground-Used Crystalline Silicon Solar Cells", izvo zvinoda zvakajeka hunhu parameters photovoltaic masero.Zvichienderana nezvinodiwa zveGB/T29195-2012, zvakasanganiswa nehunyanzvi hunhu hwen-mhando TOPCon mabhatiri, kuongororwa kwakaitwa chinhu nechinhu.Ona Tafura 1, n-mhando TOPCon mabhatiri anonyanya kufanana nemabhatiri akajairika maererano nehukuru uye chitarisiko;
Tafura 1 Kuenzanisa pakati n-mhando TOPCon bhatiri uye GB/T29195-2012 zvinodiwa
Panyaya yemagetsi ekuita ma parameter uye tembiricha coefficient, bvunzo dzinoitwa zvinoenderana neIEC60904-1 uye IEC61853-2, uye nzira dzekuyedza dzinoenderana neyakajairwa mabhatiri; izvo zvinodikanwa zvema mechanical properties zvakasiyana nemabhatiri akajairwa maererano nekukotama degree uye electrode tensile simba.Mukuwedzera, maererano nemamiriro chaiwo ekushandiswa kwechigadzirwa, muedzo wekupisa wakanyorova unowedzerwa sechinhu chakavimbika chinodiwa.Kubva pane ongororo iri pamusoro, zviedzo zvakaitwa kuti zvionekwe ma mechanic zvivakwa uye kuvimbika kwen-mhando TOPCon mabhatiri.Photovoltaic cell zvigadzirwa kubva kune vakasiyana vagadziri vane imwechete tekinoroji nzira yakasarudzwa seyekuyedza samples. Iwo masampuli akapihwa neTaizhou Jolywood Optoelectronics Technology Co., Ltd.Kuedza uku kwakaitwa mumarabhoritari ebato rechitatu uye marabhoritari ebhizinesi, uye maparamendi akadai sedhigirii rekukotama uye kusimba kwemagetsi emagetsi, kuyedza kutenderera kwekupisa uye bvunzo yekudziya kwekunyorova, uye kwekutanga-kukonzeresa kudzoreredza kuita kwakaedzwa nekusimbiswa.Kuongororwa kweMechanical Properties ye Photovoltaic CellsIyo yekukotama dhigirii uye electrode tensile simba mune mechaniki zvinhu zven-mhando TOPCon mabhatiri anoedzwa zvakananga pabhatiri shiti pacharo, uye kusimbiswa kweiyo nzira yekuyedza kunotevera.Curvature inoreva kutsauka pakati pepakati penzvimbo yepakati yemuenzaniso wakaedzwa uye ndege yereferensi yenzvimbo yepakati. Chiratidzo chakakosha chekuongorora flatness yebhatiri pasi pekunetseka nekuyedza kubhenda deformation ye photovoltaic cell.Yayo yekutanga bvunzo nzira ndeyekuyera chinhambwe kubva pakati pechifukidziro kuenda kundege yereferensi uchishandisa yakaderera dhizaini yekutamisa chiratidzo.Jolywood Optoelectronics uye Xi'an State Power Investment yakapa zvidimbu makumi maviri zveM20 saizi n-mhando TOPCon mabhatiri imwe neimwe. Kudzikama kwepasi kwaive nani pane 10mm, uye bhatiri curvature yakaedzwa nechiyereso chishandiso chine resolution iri nani pane 0.01mm.Iyo bhatiri yekubhenda bvunzo inoitwa zvinoenderana nezvinopihwa zve4.2.1 muGB/T29195-2012.Mhinduro dzebvunzo dzinoratidzwa muTable 2.
Tafura 2 Kupeta bvunzo mhinduro dzen-mhando TOPCon maseru
Iyo bhizinesi yemukati kudzora zviyero zveJolywood neXi'an State Power Investment zvese zvinoda kuti dhigirii rekukotama risakwira kupfuura 0.1mm. Zvinoenderana nekuongororwa kwemhedzisiro yebvunzo dzesampling, avhareji yekubhenda degree yeJolywood Optoelectronics uye Xi'an State Power Investment ndeye 0.056mm uye 0.053mm zvakateerana. Izvo zviyero zvakanyanya ndeye 0.08mm uye 0.10mm, zvichiteerana.Zvinoenderana nemhedzisiro yekuongororwa kwebvunzo, chinodiwa chekuti curvature yen-mhando TOPCon bhatiri haina kukwira kupfuura 0.1mm inotsanangurwa.Electrode tensile simba test verificationIyo simbi ribhoni yakabatana kune grid waya ye photovoltaic cell ne welding kuitisa ikozvino. Iyo solder ribhoni uye electrode inofanirwa kubatanidzwa zvakadzikama kuti ideredze kupikisa kwekubata uye kuve nechokwadi chekuita kwazvino kuita.Nechikonzero ichi, iyo electrode tensile simba bvunzo pane gidhi waya yebhatiri inogona kuongorora iyo electrode weldability uye welding mhando yebhatiri, inova yakajairika nzira yekuyedza yekunamatira kusimba kweiyo photovoltaic bhatiri mota.<section style="margin: 0px 0px 16px;padding: 0px;outline
