Ukugcinwa kweemodyuli ze-photovoltaic sesona siqinisekiso sithe ngqo sokunyusa ukuveliswa kwamandla kunye nokunciphisa ukulahlekelwa kwamandla.Emva koko ugxininiso lomsebenzi we-photovoltaic kunye nabasebenzi bokugcinwa kukufunda ulwazi olufanelekileyo lweemodyuli ze-photovoltaic.
Okokuqala, makhe ndikuxelele malunga nokuveliswa kwamandla e-photovoltaic kwaye kutheni siphuhlisa ngamandla ukuveliswa kwamandla e-photovoltaic.Ubume bangoku bemeko yendawo yaseTshayina kunye neendlela zophuhliso, uphuhliso olukhulu nolungalawulekiyo kunye nokusetyenziswa kwamafutha efosili, akukhawulezi nje ukuphela kobu butyebi buxabisekileyo, kodwa kubangela iingxaki eziya zisanda.Ukonakaliswa kwendalo.
I-China lelona lizwe livelisa amalahle nabathengi likhulu, kwaye phantse i-76% yamandla ayo inikezelwa ngamalahle.Oku kuthembela ngokugqithisileyo kubume bamandla efosili kubangele iimpembelelo ezimbi kakhulu kokusingqongileyo, kwezoqoqosho nakwezentlalo.Isixa esikhulu sokumbiwa kwamalahle, ukuthuthwa nokutshiswa kubangele umonakalo omkhulu kubume belizwe lethu.Ngoko ke, siphuhlisa ngamandla ukusetyenziswa kwemithombo yamandla avuselelekayo njengamandla elanga.Olu lukhetho olungenakuthintelwa kukhuseleko lwamandla elizwe lethu kunye nophuhliso oluzinzileyo.
Ukuqulunqwa kwenkqubo yokuvelisa amandla e-Photovoltaic
Inkqubo yokuvelisa amandla e-photovoltaic ikakhulu iqulethe uluhlu lwemodyuli ye-photovoltaic, ibhokisi yokudibanisa, i-inverter, utshintsho lwesigaba, i-cabinet yokutshintsha, kwaye emva koko inkqubo ehlala ingatshintshi, kwaye ekugqibeleni iza kwigridi yamandla ngokusebenzisa imigca.Ngoko yintoni umgaqo wokuvelisa amandla e-photovoltaic?
Ukuveliswa kwamandla e-Photovoltaic ikakhulu ngenxa yempembelelo ye-photoelectric yee-semiconductors.Xa i-photon ikhupha isinyithi, onke amandla ayo anokufunxwa yi-electron ekwintsimbi.Amandla afunxwa yi-electron makhulu ngokwaneleyo ukoyisa amandla omxhuzulane ngaphakathi kwesinyithi kwaye enze umsebenzi, eshiya umphezulu wesinyithi aze abaleke abe yi-Optoelectronics, iiathom zesilicon zinee-electron ezi-4 zangaphandle.Ukuba ii-athomu ze-phosphorus, ezi-athomu ze-athomu ze-phosphorus ezinee-electron ezi-5 zangaphandle, zifakwe kwi-silicon ecocekileyo, i-semiconductor yohlobo lwe-n yenziwa.
Ukuba iiathom ezineelektroni ezintathu zangaphandle, ezifana ne-athom ye-boron, zixutywe kwisilicon ecocekileyo ukwenza i-semiconductor yohlobo lwe-p, xa uhlobo lwe-p kunye nohlobo lwe-n zidityanisiwe, umphezulu woqhagamshelwano uya kwenza umsantsa weseli kwaye ube yilanga. iseli.
Iimodyuli zePhotovoltaic
Imodyuli ye-photovoltaic iyona nto encinci ye-solar edibeneyo yokudibanisa i-solar eneziko kunye noqhagamshelwano lwangaphakathi olunokubonelela ngemveliso ye-DC yodwa.Ikwabizwa ngokuba yiphaneli yelanga.Imodyuli ye-photovoltaic iyona nxalenye ephambili yenkqubo yokuvelisa amandla e-photovoltaic.Umsebenzi wayo kukusebenzisa isiphumo semitha ye-photoacoustic kwi-Solar energy iguqulwa ibe yimveliso yamandla e-DC.Xa ukukhanya kwelanga kukhanya kwiseli yelanga, ibhetri ifunxa amandla ombane ukwenza imingxunya yeefotoelectron.Ngaphantsi kwesenzo sentsimi yombane kwibhetri, ii-electron ezifotweyo kunye ne-spins ziyahlukana, kwaye ukuqokelela kweentlawulo zeempawu ezahlukeneyo kubonakala kuzo zombini iziphelo zebhetri.Kwaye uvelise uxinzelelo olubi oluveliswe ngesithombe, yiloo nto esiyibiza ngokuba yi-photovoltaic effect.
Makhe ndikwazise imodyuli ye-polycrystalline silicon photovoltaic eveliswe yinkampani ethile.Lo mzekelo unombane wokusebenza we-30.47 volts kunye namandla aphezulu angama-255 watts.Ngokufunxa amandla elanga, amandla emitha yelanga aguqulwa ngokuthe ngqo okanye ngokungathanga ngqo abe ngamandla ombane ngesiphumo sefotoelectric okanye isiphumo sefotochemical.Yenza umbane.
Xa kuthelekiswa namacandelo e-silicon e-monocrystalline, izinto ze-silicon ze-polycrystalline zilula ukwenza, zonga ukusetyenziswa kwamandla, kwaye zineendleko eziphantsi zokuvelisa, kodwa ukusebenza kakuhle kokuguqulwa kwe-photoelectric nako kuphantsi.
Iimodyuli ze-Photovoltaic zinokuvelisa umbane phantsi kokukhanya kwelanga.Zikhuselekile kwaye zithembekile, azinangxolo kwaye azikhuphi kungcoliseko, kwaye zicoceke ngokupheleleyo kwaye azilungcolisi.
Emva koko, sazisa isakhiwo sesixhobo kwaye siyiqhawule.
Ibhokisi yokuhlangana
Ibhokisi ye-photovoltaic junction yi-connector phakathi kwe-solar cell array ehlanganiswe neemodyuli zeseli zelanga kunye nesixhobo sokulawula ukutshaja kwelanga.Ikakhulu idibanisa amandla ombane avela kwiiseli zelanga kwiisekethe zangaphandle.
Iglasi epholileyo
Ukusetyenziswa kweglasi epholileyo kunye nokuhanjiswa kokukhanya okuphezulu ikakhulu ukukhusela iiseli zebhetri kumonakalo, olingana noJian Bai esithi ifilimu yethu yefowuni enomsindo idlala indima yokukhusela.
I-encapsulation
Ngenxa yokuba ifilimu isetyenziselwa ukudibanisa kunye nokulungisa iglasi epholileyo kunye neeseli zebhetri, inokucaca okuphezulu, ukuguquguquka, ukumelana nobushushu obuphantsi kakhulu kunye nokuxhathisa amanzi.
Ibha ye-tin isetyenziselwa ukudibanisa iibhetri ezintle kunye nezibi ukwenza isekethe yechungechunge, eyenza amandla ombane kwaye iholele kwibhokisi ye-junction.
Isakhelo seAluminiyam yeAluminiyam
Isakhelo semodyuli ye-photovoltaic yenziwe nge-alloy aluminium exande, enobunzima kunye nobunzima.Isetyenziselwa kakhulu ukukhusela i-crimping layer kwaye idlale indima ethile yokutywinwa kunye nenkxaso, eyona nto ingundoqo yeseli.
Iiseli zelanga ze-Polycrystalline Silicon
Iiseli zelanga ze-polycrystalline ze-silicon ziyinxalenye ephambili yemodyuli.Umsebenzi wabo oyintloko kukwenza ukuguqulwa kwe-photoelectric kunye nokuvelisa umthamo omkhulu wamandla ombane.Iiseli zelanga ze-crystalline ze-silicon zineenzuzo zeendleko eziphantsi kunye nendibano elula.
Inqwelomoya
I-backsheet inxibelelana ngokuthe ngqo nendawo yangaphandle ngasemva kwimodyuli ye-photovoltaic.Izinto zokupakisha ze-photovoltaic zisetyenziselwa ukupakisha amacandelo, ukukhusela izinto eziluhlaza kunye nezinto ezincedisayo, kwaye zihlukanise iimodyuli zelanga kwibhanti yokuphindaphinda.Eli candelo lineempawu ezintle ezifana nokuchasana nokuguga, ukuxhathisa ukugquma, ukuxhathisa amanzi, kunye nokumelana negesi.Iimbonakalo.
Ukuqukumbela
I-axis yefreyimu ephambili yemodyuli ye-photovoltaic yenziwe ngeglasi epholileyo ye-photovoltaic efakwe kwi-micro-film, iiseli, imivalo yetin, iifreyimu ze-aluminium alloy, kunye neebhokisi ze-backplane junction ukwenza iiplagi ze-SC kunye nezinye izinto eziphambili.
Phakathi kwazo, iiseli ze-silicon zekristale zilungelelaniswa ukudibanisa iiseli ezininzi phambili kwaye zibuyele umva ukuze zenze uqhagamshelo olulandelelanayo, kwaye emva koko zikhokelwe kwibhokisi yokuhlangana ngebhanti yebhasi ukwenza imodyuli yebhetri ephezulu yombane.Xa ukukhanya kwelanga kubekwe phezu komhlaba kwimodyuli, ibhodi ivelisa okwangoku ngokuguqulwa kombane., isalathiso sangoku sihamba ukusuka kwi-electrode efanelekileyo ukuya kwi-electrode engalunganga.Kukho umaleko wefilimu enecala elinye kumacala angasentla nasezantsi eseli esebenza njengento yokuncamathelisa.Umphezulu ucace kakhulu kwaye awuchaphazeleki bubushushu.Ngasemva kweglasi yi-backsheet ye-PPT eye yahlanjululwa ngokufudumeza kunye nokucoca.Ngenxa yokuba i-PPT kunye neglasi zinyibilika kwiqhekeza leseli kwaye zihambelana ngokupheleleyo.Isakhelo se-aluminium alloy sisetyenziselwa ukutywina umda wemodyuli kunye ne-silicone.Kukho iibhasi ezikhokelela ngasemva kwiphaneli yeseli.Ibhokisi yokukhokela ibhetri igxininiswe ngokumelana nokushisa okuphezulu.Sisanda kwazisa izixhobo zemodyuli ye-photovoltaic ngokuqhawula.Ubume kunye nomgaqo wokusebenza.
