Ukugcinwa kwamamojula we-photovoltaic kuyisiqinisekiso esiqondile kakhulu sokwandisa ukukhiqizwa kwamandla nokunciphisa ukulahlekelwa kwamandla.Khona-ke ukugxila kokusebenza kwe-photovoltaic kanye nabasebenzi besondlo ukufunda ulwazi olufanele lwamamojula we-photovoltaic.
Okokuqala, ake ngikutshele mayelana nokukhiqiza amandla e-photovoltaic nokuthi kungani sithuthukisa ngamandla amandla e-photovoltaic.Isimo samanje sezemvelo yaseShayina kanye nezindlela zokuthuthuka, ukuthuthukiswa okukhulu nokungalawuleki kanye nokusetshenziswa kwezibaseli ezimbiwa phansi, akusheshisi nje kuphela ukuqedwa kwale mithombo eyigugu, kodwa futhi kubangela izinkinga ezinkulu ngokwandayo.Ukulimala kwemvelo.
I-China ingumkhiqizi nomthengi omkhulu wamalahle emhlabeni, futhi cishe u-76% wamandla ayo ahlinzekwa ngamalahle.Lokhu kuthembela ngokweqile kwesakhiwo samandla kaphethiloli kubangele imithelela emibi kakhulu kwezemvelo, ezomnotho nezenhlalo.Inani elikhulu lezimayini zamalahle, ezokuthutha kanye nokushiswa kwalo lidale umonakalo omkhulu endaweni ezungezile yezwe lethu.Ngakho-ke, sithuthukisa ngamandla ukusetshenziswa kwemithombo yamandla avuselelekayo njengamandla elanga.Lokhu ukukhetha okungenakugwenywa kokuvikeleka kwamandla kwezwe lethu kanye nentuthuko esimeme.
Ukwakhiwa kwesistimu yokukhiqiza amandla e-Photovoltaic
Isistimu yokukhiqiza amandla e-photovoltaic ngokuyinhloko iqukethe i-module ye-photovoltaic array, ibhokisi lokuhlanganisa, i-inverter, ukuguqulwa kwesigaba, i-switch cabinet, bese kuba uhlelo oluhlala lungashintshiwe, futhi ekugcineni lufika kugridi yamandla ngemigqa.Ngakho-ke uyini umgomo wokukhiqiza amandla we-photovoltaic?
Ukukhiqizwa kwamandla e-Photovoltaic ikakhulukazi ngenxa yomphumela we-photoelectric wama-semiconductors.Lapho i-photon ikhanyisa insimbi, wonke amandla ayo angamuncwa i-electron ensimbi.Amandla amuncwa i-electron makhulu ngokwanele ukuba anqobe amandla adonsela phansi ngaphakathi kwensimbi futhi enze umsebenzi, ashiye ingaphezulu lensimbi futhi aphunyuke abe yi-Optoelectronics, ama-athomu e-silicon anama-electron angu-4 angaphandle.Uma ama-athomu e-phosphorus, angama-athomu e-athomu e-phosphorus anama-electron angaphandle angu-5, efakwa ku-silicon ehlanzekile, kwakheka i-semiconductor yohlobo lwe-n.
Uma ama-athomu anama-electron amathathu angaphandle, njengama-athomu e-boron, exutshwe ku-silicon ehlanzekile ukuze akhe i-semiconductor yohlobo lwe-p, lapho uhlobo lwe-p nohlobo lwe-n kuhlanganiswe ndawonye, indawo yokuxhumana izokwakha igebe leseli futhi ibe ilanga. iseli.
Amamojula we-Photovoltaic
Imojula ye-photovoltaic iyisisetshenziswa esincane kunazo zonke esingahlukaniseki sokuhlanganiswa kwamaseli elanga anesikhungo kanye noxhumano lwangaphakathi olunganikeza ukuphuma kwe-DC kuphela.Ibizwa nangokuthi iphaneli yelanga.Imojula ye-photovoltaic iyingxenye eyinhloko yalo lonke uhlelo lokukhiqiza amandla we-photovoltaic.Umsebenzi wawo ukusebenzisa umphumela wemisebe ye-photoacoustic kumandla eSolar aguqulwa abe yi-DC power output.Lapho ukukhanya kwelanga kukhanya kuseli yelanga, ibhethri lidonsa amandla kagesi ukuze likhiqize izimbobo ze-photoelectron.Ngaphansi kwesenzo senkambu kagesi ebhethrini, ama-electron akhiqiziwe nama-spins ayahlukaniswa, futhi ukunqwabelana kwamashaji ezimpawu ezihlukene kuvela emaphethelweni womabili ebhethri.Futhi ukhiqize ingcindezi engalungile ekhiqizwe yisithombe, okuyilokho esikubiza ngokuthi umphumela we-photovoltaic owenziwe ngesithombe.
Ake ngethule kuwe imojula ye-polycrystalline silicon photovoltaic ekhiqizwa inkampani ethile.Le modeli ine-voltage yokusebenza engu-30.47 volts namandla aphezulu angama-255 watts.Ngokumunca amandla elanga, amandla emisebe yelanga aguqulwa ngokuqondile noma ngokungaqondile abe amandla kagesi ngokusebenzisa umphumela we-photoelectric noma umphumela we-photochemical.Khiqiza ugesi.
Uma kuqhathaniswa nezingxenye ze-silicon ye-monocrystalline, izakhi ze-polycrystalline silicon zilula ukuzenza, zonga ukusetshenziswa kwamandla, futhi zinezindleko eziphansi zokukhiqiza zizonke, kodwa ukusebenza kahle kokuguqulwa kwe-photoelectric nakho kuphansi kakhulu.
Amamojula we-Photovoltaic angakhiqiza ugesi ngaphansi kokukhanya kwelanga okuqondile.Ziphephile futhi zithembekile, azinamsindo futhi azikhiphi ukungcola, futhi zihlanzeke ngokuphelele futhi azingcoli.
Okulandelayo, sethula isakhiwo sedivayisi futhi siyihlakaze.
Ibhokisi Le-Junction
Ibhokisi le-photovoltaic junction liyisixhumi phakathi kwe-solar cell array eyakhiwe amamojula weseli yelanga kanye nedivayisi yokulawula ukushaja kwelanga.Ngokuyinhloko ixhuma amandla kagesi akhiqizwa amaseli elanga kumasekhethi angaphandle.
Ingilazi Epholile
Ukusetshenziswa kwengilazi epholile enokudlulisa ukukhanya okuphezulu ikakhulukazi ukuvikela amaseli ebhethri emonakalweni, okulingana ne-Jian Bai ethi ifilimu yethu epholile yomakhalekhukhwini idlala indima yokuvikela.
I-Ecapsulation
Ngenxa yokuthi ifilimu isetshenziselwa kakhulu ukuhlanganisa nokulungisa ingilazi epholile kanye namaseli ebhethri, inokucaca okuphezulu, ukuguquguquka, ukumelana nokushisa okuphansi kakhulu nokumelana namanzi.
Ibha kathayela isetshenziswa ngokuyinhloko ukuxhuma amabhethri avumayo noma angalungile ukuze enze isekethe yochungechunge, ekhiqiza amandla kagesi futhi ayiholele ebhokisini lokuhlangana.
I-Aluminium Alloy Frame
Uhlaka lwemodyuli ye-photovoltaic yenziwe nge-alloy aluminium engunxande, engasindi futhi esindayo.Isetshenziselwa ikakhulukazi ukuvikela ungqimba lwe-crimping futhi idlale indima ethile yokuvala nokusekela, okuwumgogodla weseli.
Amaseli elanga e-Polycrystalline Silicon
Amaseli elanga e-polycrystalline silicon ayingxenye eyinhloko yemojula.Umsebenzi wabo oyinhloko ukwenza ukuguqulwa kwe-photoelectric futhi kukhiqize inani elikhulu lamandla kagesi.Amaseli elanga e-crystalline silicon anezinzuzo zezindleko eziphansi kanye nomhlangano olula.
Indiza engemuva
I-backsheet ixhumene ngqo nemvelo yangaphandle ngemuva kwemojula ye-photovoltaic.Izinto zokupakisha ze-photovoltaic zisetshenziselwa ikakhulukazi ukupakisha izingxenye, ukuvikela izinto ezingavuthiwe neziyisizayo, nokuhlukanisa amamojula elanga ebhandeni lokugeleza kabusha.Le ngxenye inezakhiwo ezinhle ezifana nokumelana nokuguga, ukumelana nokushisa, ukumelana namanzi, nokumelana negesi.Izici.
Isiphetho
I-axis yefreyimu eyinhloko yemodyuli ye-photovoltaic yenziwe ngengilazi ye-photovoltaic tempered ehlanganiswe ifilimu encane, amaseli, imigoqo yamathini, amafreyimu we-aluminium alloy, namabhokisi okuhlangana kwe-backplane ukuze enze ama-plug we-SC nezinye izingxenye eziyinhloko.
Phakathi kwawo, amaseli e-silicon e-crystalline ahlanganiswe ukuze axhume amaseli amaningi phambili futhi ahlehle ukuze akhe uchungechunge lokuxhunywa, abese eholelwa ebhokisini lokuhlangana ngebhande lebhasi ukuze akhe imojuli yebhethri yamandla okukhipha amandla aphezulu.Lapho ukukhanya kwelanga kusethwe ebusweni bemodyuli, ibhodi likhiqiza okwamanje ngokuguqulwa kukagesi., isiqondiso samanje sigeleza sisuka ku-electrode eqondile siye ku-electrode engalungile.Kunongqimba lwefilimu enohlangothi olulodwa ezinhlangothini ezingenhla nezingezansi zengqamuzana ezisebenza njengento enamathelayo.Ingaphezulu libonisa ngale kakhulu futhi alikwazi ukumelana nokufutheka.Ingemuva lengilazi i-backsheet ye-PPT efakwe i-laminated ngokushisisa nokuhlanza.Ngoba i-PPT nengilazi kuncibilika kucezu lweseli futhi kunamathele kuphelele.Uhlaka lwe-aluminium alloy lusetshenziselwa ukuvala unqenqema lwemojuli nge-silicone.Kukhona imikhondo yamabhasi ngemuva kwephaneli yeseli.Ibhokisi eliholayo lebhethri lilungiswe ukumelana nezinga lokushisa eliphezulu.Sisanda kwethula imishini yemojula ye-photovoltaic ngokuhlakazeka.Isakhiwo kanye nomgomo wokusebenza.
