1. Ngemva kokuqedwa kokusebenza kwengxenye yelanga, ukuhlolwa kwamandla kuyenziwa, futhi amandla engxenye avamile, kodwa ikhasimende lithole ukuncishiswa kwamandla lapho ingxenye ifakiwe futhi isetshenziswa. Iningi lalesi simo sibangelwa i-photolithosis yebhethri.

Lesi sihloko sizochaza ngokuhlelekile, kafushane ukwenzeka kwezithombe. 2. I-Photoelectric attenuation yezingxenye ze-photovoltaic ingahlukaniswa ngezigaba ezimbili: ukubola kokuqala kwe-photolithonal kanye nokuguga ukuguga.

2.1 I-photolithoma yokuqala ye-photolithosis, okungukuthi, amandla okukhipha imodyuli ye-photovoltaic inokwehla okukhulu ezinsukwini zokuqala zokusetshenziswa kokuqala, kodwa-ke ijwayele ukuzinza. Isizathu esibalulekile esibangela lesi simo ukuthi inkimbinkimbi ye-borogenic ku-p-type (borborid) crystalline silicon yehliswa.

Ngokushintsha i-p-type dopant, i-photovollection ye-photovollection iyancipha ngokuphumelelayo ngokushintshwa kwe-boron; noma ishidi lebhethri liya phambili, okuwukucushwa kwebhethri kokuqala ngaphambi kokuhlanganisa. Ingalawulwa phakathi kwebanga elincane kuyilapho ithuthukisa nokuqina kokukhiphayo kwengxenye. Ama-Photocatalyst ahlobene namaphakethe ebhethri, futhi incazelo yabakhiqizi bezingxenye ukukhetha izingcezu zebhethri zekhwalithi ephezulu ukunciphisa umthelela wokuthwebula izithombe.

2.2. Ukunciphisa ukuguga kokunciphisa ukuguga kubhekisela ekwehleni kwamandla okunensa ekusetshenzisweni kwesikhathi eside, futhi imbangela ebalulekile yebhethri ihlobene nokuncipha kancane kwebhethri, futhi ihlobene nokuwohloka kokusebenza kwempahla yephakheji.

Phakathi kwabo, kuyisizathu esibalulekile sokuwohloka kokusebenza kokugcinwa kwengxenye ngesikhathi sokushiswa kokukhanya kwe-ultraviolet. Ukukhanya okuhlala isikhathi eside kwemisebe ye-ultraviolet, kuvumela i-EVA kanye ne-backplane (isakhiwo se-TPE) isenzakalo esidala esishintsha umbala ophuzi, okubangela ukuba ukudluliswa kokukhanya komhlangano kwehle, futhi kubangele amandla ehle. Lokhu kudinga ukuthi abathengisi bezingxenye kufanele balawule ngokuqinile lapho bekhetha i-EVA nezindiza ezingemuva, futhi izinto ezikhethiwe kufanele zibe zinhle kakhulu ekumelaneni nokuguga ukuze kuncishiswe ukuncishiswa okuhlanganisiwe ngenxa yokuguga okuphelele.

3. Isimo sokuqala sokunciphisa isithombe sohlobo lwe-p-type (borbord) crystal silicon solar cell sibonwa eminyakeni engaphezu kwengu-30 edlule, bese abantu benze ucwaningo oluningi lwesayensi. Ikakhulukazi, eminyakeni yamuva nje, ucwaningo lwesayensi lwathola ukuthi luhlobene nokuhlushwa kwe-boron oxygen esisicwecweni se-silicon, futhi umbono wawo wonke umuntu ongaguquguquki uyakhanyiswa noma uvimbela okwamanje i-boron nomoya-mpilo ku-silicon wafer ukuze kwakhiwe ama-boron oxygen complexes, ngaleyo ndlela kunciphisa ukuphila kwengane. ifilimu izoba namazinga ahlukene okubola ngemva kokukhanya, kanye ne-boron, umoya-mpilo ku-wafer ye-silicon.

Uma kukhulu okuqukethwe, kuyanda izinhlanganisela ze-boraboalaxic ezivela emzimbeni ngaphansi kokukhanya noma isigameko samanje, ukwanda okukhulu kwempilo ephansi kakhulu. Ngomoya-mpilo ophansi, ohlanganisiwe, i-silicon wafer ye-phosphorus, impilo yayo ye-colossono inyukile ngesikhathi esisha sokuthatha izithombe, ukubola sekukonke kuncane kakhulu. 4.

Isixazululo 4.1. Thuthukisa izenzakalo zangaphambi kwesikhathi ze-photolithix zokusebenza kwamaseli elanga e-silicon eyodwa yekristalu Okubalulekile kumaseli elanga e-crystal silicon eyodwa, kanye ne-amplitude yokuqala ye-photolithonal attenuation yokusebenza kahle kokuguqulwa kuncane.

Ngakho-ke, izakhiwo ze-silicon plate ngokwayo zinquma izinga le-photorelation yokuqala yokusebenza kwamaseli elanga. Ngakho-ke, ukuxazulula inkinga yokuqala ye-photolithosis yezingxenye ze-photovoltaic. Kuyadingeka ukuxazulula inkinga ye-silicon.

Okulandelayo kuzoxoxa ngezindlela eziningana. A. Ikhwalithi yamabha ekristalu eyodwa athuthukisa i-boron-doped straight single crystal silicon rod iyakhathaza ngempela.

Uma lesi simo sizothinta kakhulu ukuthuthukiswa okunempilo kwemboni ye-photovoltaic ekuxubeni kwemikhiqizo ye-crystal eyodwa ye-Dragonflite Ukuthuthukisa izinkinga nokuthuthukiswa e-China: 1) Kusukela ukushoda kwasekuqaleni kwe-silicon ye-polycrystalline ephezulu ye-high-purity, ezinye izinkampani zokudonsa izintambo ziye zahlanganisa ezinye izinqwaba zama-macerate okungafanele zisetshenziswe kanye nokunye okuqukethwe kokungcola okuyingozi. Amabhethri elanga akhiqizwa esebenzisa izinto ezinjalo awagcini nje ngokusebenza kahle, kodwa i-photolithosis yokuqala inkulu kakhulu. Sicela kakhulu ngezinto ezisezingeni eliphansi ze-silicon.

2) Imfucuza yohlobo lwe-N-silicon wafers ekuhlanganisweni okuphezulu kwe-polycrystalline silicon ezintweni ezisezingeni eliphakeme ze-silicon ye-polycrystalline, njll. I-boron silicon rod eyakhiwe iwuhlobo oluphezulu lwe-P-crystal material enxeshezelwe. Nakuba i-resistivity ifanelekile, ukugxiliswa kwe-boron oxygen kuphezulu kakhulu, okuholela ekunciphiseni okukhulu kwe-photolithonal yokusebenza kwamaseli elanga.

Asidingi kakhulu i-silicon yohlobo lwe-N-resistivity ephansi. I-3) Ezinye izinkampani zidonsa inqubo yenduku ayinqunyelwe, okuqukethwe kwe-oksijini ku-silicon ye-crystalline kuphezulu kakhulu, ukucindezeleka kwangaphakathi kukhulu, ukukhubazeka kwe-dislocation kuphezulu, futhi ukuphikiswa akulingani, konke kuthinta ukusebenza kahle nokuzinza kweseli yelanga. Sifisa ukuthuthukisa umsebenzi wokudonsa.

Lawula okuqukethwe komoyampilo. Iseli lelanga elenziwe nge-silicon wafer engenhla line-photolithonal attenuation enkulu, ezodlula ububanzi bekhasimende obamukelekayo. Eqinisweni, inqubo yokudonsa okuqondile kwekristalu eyodwa ivuthiwe.

Uma nje sibeka ikhwalithi yezinto ezibonakalayo, ngokusho kwenqubo yenduku ehlelekile, ikhwalithi yenduku ye-silicon ingalawulwa kangcono. B. Ikhwalithi yomkhiqizo we-crystal silicon rod ethuthukisiwe Le nqubo ayikwazi ukulawula kuphela ukuhlushwa komoya-mpilo ku-crystal eyodwa, kodwa futhi ithuthukise i-silicon single crystal, ukufana kwe-radial resistivity.

Inqubo isiqalile ukulingwa e-China. C. I-Single Crystal Silicon Process (FZ) ethuthukisiwe ukuze kuthuthukiswe inqubo ye-crystal silicon eyodwa ngenqubo yesifunda encibilikisiwe ye-crystal crystal silicon (Fz) ukuvimbela inani elikhulu le-oksijini ku-crystal crystal ewuketshezi enqubweni yokudonsa okuqondile, ngaleyo ndlela kuxazululwe kahle i-P-uhlobo (i-boron boron) ) Into yokuqala ye-photolithix yamaseli elanga.

Ngenxa yezindleko eziphezulu ze-FZ, kubalulekile kuma-wafers e-silicon e-IC namanye amadivaysi e-semiconductor, kodwa ezinye izinkampani ziye zalungisa inqubo ye-FZ, ukunciphisa izindleko. Yenziwe nge-solar battery silicon wafers. Ezinye zezinduku zasekhaya zenze lesi sici somsebenzi wokuhlola D, ukushintsha i-dopant, kusetshenziswa ibhethri elenziwe nge-silicon-doped silicon ene-ballium, ayitholanga into yokuqala ye-photoreal ye-solar cell, kodwa futhi yaxazulula isigaba sokuqala se-solar cell.

Enye yezindlela. E, sebenzisa ishidi le-silicon lohlobo lwe-P lohlobo lwe-N-silicon-doped N usebenzisa iwafa ye-silicon kanye nendlela yokuxazulula inkinga yokuhlolwa kokuqala kwebhethri, kodwa kusukela kunqubo yamanje yebhethri yokunyathelisa kwesikrini sezimboni, 诰Ayikho inzuzo ekusebenzeni kahle kokuguqulwa kanye nezindleko zokukhiqiza. Ezinye izinqubo ezibalulekile ziyadingeka ukuze kuxazululwe 4.

2. Ukuncishiswa kokukhanya kwangaphambilini kwebhethri kubangelwa ukuncishiswa kwesithombe kwangaphambi kwesikhathi komhlangano we-photovoltaic, futhi ibhethri liyakhanyiswa. I-Plearance, ukuze i-photoa yakuqala yebhethri yenzeke ngaphambi kokuba ingxenye ikhiqizwe.

I-photolithonization yokuqala yezingxenye ze-photovoltaic incane kakhulu, ingalawulwa ngaphakathi kwamaphutha okulinganisa. Ngesikhathi esifanayo, futhi kunciphisa kakhulu ithuba lezindawo ezishisayo ezingxenyeni ze-photovoltaic. 5.

Isifinyezo sinyusa ukuqina kokukhiphayo kwezingxenye ze-photovoltaic, kuletha izinzuzo eziningi kubasebenzisi bethu. Naphezu kwezibikezelo zokukhanya, kuyindlela yokugcwalisa isiboshwa, kodwa ngaphambi kokuba izinga le-silicon wafer lingathuthukisiwe ngokuphumelelayo, ukusetshenziswa kwale ndlela ukuxazulula izinyathelo ezisebenzayo ze-photolithitation yokuqala yezingxenye ze-photovoltaic.
