1. Mushure mekushanda kwechikamu chezuva chapedzwa, kuedza kwesimba kunoitwa, uye simba rechikamu rinowanzoitika, asi mutengi akagamuchira simba rekudzivirira apo chikamu chacho chakaiswa uye chinoshandiswa. Zvizhinji zvechiitiko ichi chinokonzerwa ne photolithosis yebhatiri.

Ichi chinyorwa chichaita zvakarongeka, kutsanangura muchidimbu chiitiko chephotoloration. 2. Photoelectric attenuation ye photovoltaic components inogona kukamurwa kuita nhanho mbiri: yekutanga photolithonal kuora uye kuchembera attenuation.

2.1 Iyo yekutanga photolithoma yekutanga photolithosis, ndiko kuti, simba rekubuda re photovoltaic module rine kuderera kukuru mumazuva ekutanga ekutanga kushandiswa, asi zvino inowanzoita kugadzikana. Chikonzero chakakosha chinokonzera chiitiko ichi ndechekuti borogenic complex mu-p-type (borborid) crystalline silicon inoderedzwa.

Nokushandura p-type dopant, iyo photovollection ye photovollection inonyatso kuderedzwa nekutsiva boron; kana bheti rebhatiri riri kuenderera mberi, inova yekutanga photolithonal attenuation yebhatiri pamberi pegungano. Inogona kudzorwa mukati mechikamu chidiki uku ichivandudzawo kugadzikana kwekubuda kwechikamu. Photocatalysts ine hukama nebhatiri mapaketi, uye zvinorehwa zvevagadziri vechikamu ndezvekusarudza emhando yepamusoro bhatiri zvimedu kudzikisa pesvedzero yephotoloration.

2.2. Kuchembera kuchembera kuchembera kuderera kunoreva kuderera kwesimba kunonoka mukushandiswa kwenguva refu, uye chikonzero chakakosha chebhatiri chine chekuita nekunonoka kunonoka kwebhatiri, uye zvakare zvine chekuita nekuderera kwekuita kwepakeji zvinhu.

Pakati pavo, ndicho chikonzero chakakosha chekuparara kwechikamu chekugadzirisa kushanda panguva yekuvhenekera kwe ultraviolet chiedza. Kwenguva yakareba irradiation ye ultraviolet rays, inobvumira EVA uye backplane (TPE chimiro) chekare yero-kuchinja chiitiko, zvichiita kuti chiedza chekufambisa kwegungano chiwire, uye chinokonzera simba kudonha. Izvi zvinoda kuti vatengesi vechikamu vanofanirwa kudzora zvakanyanya pakusarudza EVA uye backplanes, uye zvinhu zvakasarudzwa zvinofanirwa kuve zvakanakisa mukuramba kuchembera kudzikisa kudzikisira kwese nekuda kwekuchembera.

3. Iyo yekutanga foto attenuation chiitiko cheiyo p-mhando (borborid) crystal silicon solar cell inocherechedzwa anopfuura makore makumi matatu apfuura, uye ipapo vanhu vakaita yakawanda tsvakiridzo yesainzi. Kunyanya, mumakore achangopfuura, tsvakurudzo yesayenzi yakawana kuti yakabatana neboron oxygen concentration musilicon wafer, uye maonero emunhu wese anonyatsoenderana anovhenekerwa kana kuti iye zvino anodzivisa boron uye oksijeni mumucheka wesilicon kuti uite boron oxygen complexes, nokudaro kuderedza hupenyu hwemwana. firimu richava nemadhigirii akasiyana ekuora mushure mechiedza, uye boron, okisijeni mumucheka wesilicon.

Iyo yakakura zviri mukati, iyo yakanyanya boraboalaxic composites inoonekwa mumuviri pasi pekuvhenekerwa kana chiitiko chezvino, iyo inowedzera kuwedzera muhupenyu hwakaderera. Mune yakaderera okisijeni, yakasanganiswa, phosphorous silicon wafer, hupenyu hwayo hwe colossono hwawedzera nenguva nyowani yekutora mifananidzo, kuora kwese kudiki zvakanyanya. 4.

Solution 4.1. Kuvandudza yekutanga photolithix phenomena yekushanda kwesilicon single crystal quality solar masero Yakakosha pane imwechete crystal silicon solar masero, uye yekutanga photolithonal attenuation amplitude yekushandura inoshanda idiki.

Saka, zvimiro zvesilicon plate pachayo zvinotarisa dhigirii rekutanga photorelation ye solar cell performance. Nokudaro, kugadzirisa dambudziko rekutanga photolithosis yezvikamu zve photovoltaic. Izvo zvinodiwa kugadzirisa dambudziko resilicon.

Zvinotevera zvichakurukura nzira dzinoverengeka. A. Hunhu hwemamwe mabhawa ekristaro anovandudza boron-doped yakatwasuka imwe crystal silicon rod iri kunetsa chaizvo.

Kana mamiriro aya achakanganisa zvakanyanya kukura kwehutano hwe photovoltaic industry mumusanganiswa weDragonflite single crystal products Kuvandudza matambudziko nekuvandudzwa muChina: 1) Kubva pakatanga kushayikwa kwepamusoro-kuchena kwepolycrystalline silicon, mamwe makambani ekudhonza tsvimbo akabatanidza mamwe macerate asingafaniri kushandiswa uye zvimwe zvinokuvadza zvinosvibisa zviri mukati. Mabhatiri ezuva anogadzirwa achishandisa zvinhu zvakadaro haasi kungoita zvishoma, asi yekutanga photolithosis yakakura zvikuru. Isu tinokumbira zvakasimba kune yakaderera mhando silicon zvinhu.

2) Waste N-mhando silicon wafers mune yakakwirira-kuchena polycrystalline silicon inosanganiswa mune yakakwirira-kuchena polycrystalline silicon zvinhu, nezvimwe. Iyo boron silicon tsvimbo inogadzirwa yakakwira yakabhadharwa P-mhando imwe crystal zvinhu. Kunyangwe iyo resistivity yakakodzera, iyo boron oxygen concentration yakakwira zvakanyanya, zvichikonzera yakakura photolithonal attenuation yesolar cell performance.

Isu tinoda zvakanyanya hapana yakaderera resistivity N-mhando silicon. 3) Mamwe makambani anodhonza nzira yetsvimbo haina kuganhurirwa, iyo okisijeni yemukati mucrystalline silicon yakanyanya, kushushikana kwemukati kwakakura, kukanganiswa kweiyo dislocation kwakakwira, uye resistivity haina kuenzana, zvese zvinokanganisa kushanda uye kugadzikana kwesolar cell. Tinoshuvira kuvandudza hunyanzvi hwekudhonza.

Dzora okisijeni zvirimo. Iyo solar sero yakagadzirwa nepamusoro silicon wafer ine yakakura photolithonal attenuation, iyo inodarika chiyero chemutengi chinogamuchirwa. Muchokwadi, iyo yakatwasuka yekudhonza imwe chete crystal process yakakura.

Chero bedzi isu tichiisa hutano hwezvinhu, maererano nemaitiro ekugadzirisa tsvimbo, kunaka kwesilicon tsvimbo inogona kudzorwa zviri nani. B. Yakavandudzwa imwe crystal silicon rod chigadzirwa chemhando Iyi nzira haigone kungodzora iyo oxygen kuunganidzwa mumakristasi imwe chete, asi zvakare inovandudza iyo silicon single crystal, radial resistivity kufanana.

Chirongwa ichi chatanga kuyedza kuChina. C. Yakavandudzwa Single Crystal Silicon Process (FZ) yekuvandudza imwechete crystal silicon process neyedunhu yakanyungudutswa imwe chete crystal silicon process (Fz) kudzivirira huwandu hukuru hweokisijeni mumvura yesilicon crystal mune yakatwasuka nzira yekudhonza, nekudaro kunyatsogadzirisa P-mhando (boron boron) ) Pakutanga photolithix chiitiko chemasero ezuva.

Nekuda kwemutengo wakakwira weFZ, zvakakosha kune silicon wafers yeIC nemimwe semiconductor zvishandiso, asi mamwe makambani akagadziridza FZ process, kuderedza mutengo. Yakagadzirwa nesolar bhatiri silicon wafers. Mimwe yetsvimbo yemumba yakaita iyi chikamu chebasa rekuyedza D, kushandura dopant, uchishandisa bhatiri rakagadzirwa nesilicon-doped silicon ine ballium, haina kuwana yekutanga photoreal phenomenon yesolar cell, asi zvakare yakagadzirisa danho rekutanga resolar cell.

Imwe yenzira. E, shandisa p-mhando N-mhando yesilicon-doped N-mhando yesilicon sheet uchishandisa silicon wafer uye nzira yekugadzirisa dambudziko rekutanga kuyedzwa bhatiri, asi kubva kune yazvino maindasitiri skrini yekudhinda 诰 bhatiri maitiro, 诰 Hapana chakanakira mukutendeuka uye mutengo wekugadzira. Mamwe maitiro akakosha anodiwa kugadzirisa 4.

2. Kuvhenekera kwekare kuderedzwa kwebhatiri kunokonzerwa nekutanga pikicha attenuation yemusangano we photovoltaic, uye bhatiri rinovhenekerwa. Plearance, kuitira kuti yekutanga photoa yebhatiri iitike chikamu chisati chagadzirwa.

Early photolithonization ye photovoltaic components iduku zvikuru, inogona kudzorwa mukati mezvikanganiso zvekuyera. Panguva imwecheteyo, inoderedzawo zvakanyanya mukana wezvitsva zvinopisa muzvikamu zve photovoltaic. 5.

Pfupiso inowedzera kugadzikana kwekubuda kwe photovoltaic components, kuunza mamwe mabhenefiti kune vashandisi vedu. Pasinei nemararamiro echiedza, inzira yekuzadzazve musungwa, asi musati wehutano hwesilicon wafer isati yanyatsogadziriswa, kushandiswa kweiyi nzira ndeyekugadzirisa matanho anobudirira ekutanga photolithitation ye photovoltaic components.
