1. Emva kokusebenza kwecandelo lelanga ligqityiwe, uvavanyo lwamandla luyenziwa, kwaye amandla amacandelo aqhelekileyo, kodwa umthengi ufumene ukutshatyalaliswa kwamandla xa icandelo lifakwe kwaye lisebenza. Uninzi lwale nto ibangelwa yifotolithosis yebhetri.

Eli nqaku liza kuchaza ngokucwangcisiweyo, ngokufutshane isenzeko sokufota. 2. I-Photoelectric attenuation yamacandelo e-photovoltaic inokwahlulwa ibe ngamanyathelo amabini: ukubola kokuqala kwe-photolithonal kunye nokuguga.

2.1 I-photolithoma yokuqala ye-photolithosis, oko kukuthi, amandla okuvelisa imodyuli ye-photovoltaic inokwehla okukhulu kwiintsuku zokuqala zokusetyenziswa kokuqala, kodwa ke ijwayele ukuzinza. Isizathu esibalulekileyo esibangela le nto kukuba i-borogenic complex in the p-type (borborid) crystalline silicon iyancipha.

Ngokutshintsha i-p-type dopant, i-photovollection ye-photovollection iyancitshiswa ngokufanelekileyo ngokutshintshwa kwe-boron; okanye ishiti lebhetri libheke phambili, ekukuqala ukuthotywa kwefotolithonal yebhetri phambi kwendibano. Inokulawulwa ngaphakathi kwinqanaba elincinci ngelixa likwaphucula ukuzinza kwemveliso yecandelo. I-Photocatalysts inxulumene neepakethi zebhetri, kwaye intsingiselo yabavelisi becandelo kukukhetha izilayi zebhetri eziphezulu zokunciphisa impembelelo ye-photoloration.

2.2. Ukuthomalalisa ukuthomalalisa ukwaluphala kubhekiselele ekwehleni okucothayo kwamandla kusetyenziso lwexesha elide, kwaye unobangela obalulekileyo webhetri unxulumene nokucutha kancinci kwebhetri, kwaye ikwanxulumene nokuthotywa kokusebenza kwempahla yephakheji.

Phakathi kwabo, isizathu esibalulekileyo sokuthotywa kokusebenza kokugcinwa kwecandelo ngexesha lokukhanya kwe-ultraviolet. I-irradiation yexesha elide lemisebe ye-ultraviolet, ivumela i-EVA kunye ne-backplane (isakhiwo se-TPE) esineminyaka engama-yellow-eguqukayo, ebangela ukuba ukuhanjiswa kokukhanya kwendibano kuwele, kwaye kubangele ukuba amandla awele. Oku kufuna ukuba abathengisi becandelo kufuneka balawule ngokungqongqo xa bekhetha i-EVA kunye ne-backplanes, kwaye izinto ezikhethiweyo kufuneka zibe zibalaseleyo kakhulu ekuxhathiseni ukuguga ukuze kuncitshiswe ukucutha okuhlangeneyo ngenxa yokuguga ngokubanzi.

3. Isiganeko sokuqala sokuthomalalisa ifoto yohlobo lwe-p (i-borbord) ye-crystal silicon yeseli yelanga ibonwa ngaphezu kweminyaka engama-30 eyadlulayo, emva koko abantu baye benza uphando oluninzi lwezenzululwazi. Ngokukodwa, kwiminyaka yakutshanje, uphando lwezenzululwazi lufumene ukuba lunxulumene noxinaniso lwe-oksijini ye-boron kwi-silicon wafer, kwaye imbono yomntu wonke ehambelanayo iyakhanyiswa okanye ngoku inqanda i-boron kunye neoksijini kwi-silicon wafer ukwenza i-boron oxygen complexes, ngaloo ndlela inciphisa ubomi bomntwana. ifilimu iya kuba needigri ezahlukeneyo zokubola emva kokukhanya, kunye ne-boron, ioksijini kwi-silicon wafer.

Ubuninzi bomxholo, i-boraboalaxic composites engaphezulu ibonakala emzimbeni phantsi kokukhanya okanye isiganeko sangoku, ukwanda okukhulu kobomi obuphantsi. Kwioksijini ephantsi, edityanisiweyo, iphosphorous silicon wafer, ubomi bayo be-colossono bonyukile kunye nexesha elitsha lokufota, ukubola kukonke kuncinci kakhulu. 4.

Isisombululo 4.1. Ukuphucula i-photolithix phenomena yokuqala yokusebenza kwe-silicon enye yekristale esemgangathweni yeeseli zelanga Kubalulekile kwiiseli zelanga ze-crystal silicon enye, kunye ne-photolithonal attenuation amplitude yokuqala yokusebenza kakuhle kokuguqulwa kuncinci.

Ke, iipropathi ze-silicon plate ngokwayo zimisela inqanaba le-photorelation yokuqala yokusebenza kweeseli zelanga. Ngoko ke, ukusombulula ingxaki ye-photolithosis yokuqala yamacandelo e-photovoltaic. Kuyimfuneko ukusombulula ingxaki ye-silicon.

Oku kulandelayo kuza kuxubusha iindlela ezininzi. A. Umgangatho weminye imivalo yekristale enye ephucula intonga ye-boron-doped ethe tye ye-silicon yekristale iyaxhalabisa ngokwenene.

Ukuba le meko iya kuchaphazela kakhulu uphuhliso oluphilileyo lwemboni ye-photovoltaic kumxube we-Dragonflite imveliso ye-crystal eyodwa Ukuphucula iingxaki kunye nokuphuculwa kwe-China: 1) Ukususela ekunqongopheni kwe-silicon ye-polycrystalline ye-polycrystalline yasekuqaleni, ezinye iinkampani zentonga zokutsala ziye zadibanisa ubunzima be-macerates obungafuneki ukuba busetyenziswe kunye nezinye izinto ezinobungozi eziqulethe izinto ezingcolileyo. Iibhetri zelanga eziveliswayo kusetyenziswa izinto ezinjalo azikho nje ukusebenza okuphantsi, kodwa i-photolithosis yokuqala inkulu kakhulu. Sicela ngamandla izixhobo ze-silicon ezisezantsi.

2) Inkunkuma yohlobo lwe-N-uhlobo lwe-silicon yafers kwi-high-purity polycrystalline silicon idibanisa kwizinto eziphakamileyo ze-polycrystalline silicon, njl. Intonga ye-silicon eyenziweyo yimbuyekezo ephezulu yohlobo lwe-P yemathiriyeli yekristale enye. Nangona i-resistivity ifanelekile, i-boron oxygen concentration iphezulu kakhulu, ibangela ukuthotywa kwe-photolithonal enkulu yokusebenza kweeseli zelanga.

Sifuna ngamandla ukuba akukho ukumelana ne-N-uhlobo lwesilicon. I-3) Ezinye iinkampani zidonsa inkqubo yentonga ayikhawulelwanga, umxholo we-oksijini kwi-silicon ye-crystalline iphezulu kakhulu, uxinzelelo lwangaphakathi lukhulu, i-defect dislocation iphezulu, kwaye ukuxhathisa akulingani, zonke zichaphazela ukusebenza kakuhle kunye nokuzinza kweseli yelanga. Sinqwenela ukuphucula umsebenzi wokutsala.

Lawula umxholo weoksijini. Iseli yelanga eyenziwe ngesisica sesilicon esingentla sine-photolithonal attenuation enkulu, eya kuthi ibe ngaphaya kobubanzi bomthengi owamkelekileyo. Ngapha koko, inkqubo yokutsala ngokuthe tye kwekristale enye ivuthiwe.

Ngethuba nje sibeka umgangatho wezinto eziphathekayo, ngokwenkqubo yentonga esemthethweni, umgangatho wentonga ye-silicon unokulawulwa ngcono. B. Ukuphucula umgangatho wemveliso ye-crystal ye-silicon yentonga Le nkqubo ayikwazi ukulawula kuphela ukuxinwa kwe-oksijini kwi-crystals enye, kodwa iphinde iphucule i-silicon enye yekristale, ukufana kwe-radial resistivity.

Inkqubo iqalile ukulingwa eTshayina. C. Ukuphuculwa kweSilicon ye-Crystal Silicon Process (FZ) yokuphucula inkqubo ye-crystal silicon enye yinkqubo ye-silicon etyhidiweyo enye ye-crystal silicon (Fz) ukukhusela inani elikhulu le-oksijini kwikristale ye-silicon ye-liquid kwinkqubo yokutsala ngokuthe tye, ngaloo ndlela isombulula ngokucokisekileyo i-P-uhlobo (i-boron boron) ) Isiganeko sokuqala se-photolithix yeeseli zelanga.

Ngenxa yeendleko eziphezulu ze-FZ, kubalulekile kwi-silicon wafers ye-IC kunye nezinye izixhobo ze-semiconductor, kodwa ezinye iinkampani ziye zahlaziya inkqubo ye-FZ, ukunciphisa iindleko. Yenziwe ngeentsimbi ze-silicon zebhetri yelanga. Ezinye zeentonga zasekhaya ziye zenza le nkalo yomsebenzi wokuvavanya D, ukutshintsha i-dopant, usebenzisa ibhetri eyenziwe nge-silicon-doped silicon kunye ne-ballum, ayizange ifumane into yokuqala ye-photorealic yeseli yelanga, kodwa yasombulula inqanaba lokuqala leseli yelanga.

Enye yeendlela. E, sebenzisa i-p-uhlobo lwe-N-uhlobo lwe-silicon-doped N-uhlobo lwe-silicon sheet usebenzisa i-silicon wafer kunye nendlela yokusombulula ingxaki yovavanyo lokuqala lwebhetri, kodwa ukusuka kushicilelo lwangoku lwesikrini soshicilelo 诰 inkqubo yebhetri, 诰 Akukho nzuzo ekuguquleni ukusebenza kakuhle kunye neendleko zokuvelisa. Ezinye iinkqubo eziphambili ziyafuneka ukusombulula 4.

2. Ukutshatyalaliswa kwangaphambili kokukhanya kwebhetri kubangelwa ukutshatyalaliswa kwesithombe sokuqala kwendibano ye-photovoltaic, kwaye ibhetri iyakhanyiswa. I-Plearance, ukuze ifotoa yokuqala yebhetri yenzeke ngaphambi kokuba icandelo lenziwe.

I-photolithonization yokuqala yamacandelo e-photovoltaic incinci kakhulu, inokulawulwa ngaphakathi kweempazamo zokulinganisa. Ngexesha elifanayo, kwakhona kunciphisa kakhulu ithuba leendawo ezishushu kumacandelo e-photovoltaic. 5.

Isishwankathelo sonyusa ukuzinza kwemveliso yamacandelo e-photovoltaic, kuzisa izibonelelo ezininzi kubasebenzisi bethu. Ngaphandle kokukhanya kwangaphambili, yindlela yokuzalisa ibanjwa, kodwa ngaphambi kokuba umgangatho we-silicon wafer ungaphuculwanga ngokufanelekileyo, ukusetyenziswa kwale ndlela kukusombulula amanyathelo asebenzayo kwi-photolithitation yokuqala yamacandelo e-photovoltaic.
