Umbulali ongabonakali wokuphepha kwesiteshi samandla e-photovoltaic——Ukufakwa okuxubile kwesixhumi

I-solar cell ingenye yezingxenye eziyinhloko ohlelweni lokuphehla amandla elanga, futhi iseli lelanga lingakwazi ukukhiqiza kuphela i-voltage engaba ngu-0.5-0.6 volts, ephansi kakhulu kune-voltage edingekayo ukuze isetshenziswe ngempela.Ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezingokoqobo, amangqamuzana elanga amaningi adinga ukufakwa izintambo kumamojula elanga, bese amamojula amaningi akhiwa abe yiqoqo ngokusebenzisa izixhumi ze-photovoltaic ukuze athole i-voltage edingekayo kanye namanje.Njengenye yezingxenye, isixhumi se-photovoltaic siphinde sithintwe yizinto ezifana nemvelo yokusetshenziswa, ukuphepha kokusetshenziswa, nempilo yesevisi.Ngakho-ke,isixhumi siyadingeka ukuze sibe nokwethembeka okuphezulu.

Izixhumi ze-Photovoltaic, njengengxenye yamamojula we-solar cell, kufanele zikwazi ukusetshenziswa ngaphansi kwezimo ezinzima zemvelo ngezinguquko ezinkulu zokushisa.Nakuba isimo sezulu semvelo ezindaweni ezahlukene zomhlaba sihlukile, futhi isimo sezulu endaweni efanayo sihluka kakhulu, umthelela wesimo sezulu semvelo ezintweni kanye nemikhiqizo ungafingqwa ngezinto ezine ezinkulu: okokuqala,imisebe yelanga, ikakhulukazi imisebe ye-ultraviolet.Umthelela ezintweni ze-polymer ezifana nepulasitiki nenjoloba;ulandelwa nguizinga lokushisa, lapho ukushintshana kokushisa okuphezulu nokuphansi kuyisivivinyo esinzima sezinto ezibonakalayo nemikhiqizo;Ngaphezu kwalokho,umswakamanjengemvula, iqhwa, isithwathwa, njll. nezinye izinto ezingcolisayo njengemvula ene-asidi, i-ozone, njll. Umthelela ezintweni.Ngaphezu kwalokho,isixhumi sidingeka ukuthi sibe nokusebenza okuphezulu kokuvikela ukuphepha kukagesi, futhi impilo yesevisi kufanele ibe ngaphezu kweminyaka engama-25.Ngakho-ke, izidingo zokusebenza kwezixhumi ze-photovoltaic yilezi:

(1) Isakhiwo siphephile, sithembekile futhi kulula ukusisebenzisa;
(2) Inkomba ephezulu yokumelana nemvelo nesimo sezulu;
(3) Izidingo zokuqina okuphezulu;
(4) Ukusebenza okuphezulu kokuphepha kukagesi;
(5) Ukuthembeka okuphezulu.

Uma kuziwa kuzixhumi ze-photovoltaic, umuntu kufanele acabange nge-Stäubli Group, lapho kwazalwa khona isixhumi sokuqala se-photovoltaic emhlabeni.“I-MC4", omunye weStäubli'sI-Multi-Contactuhla olugcwele lwezixhumi zikagesi, luhlangabezane neminyaka eyi-12 selokhu lwasungulwa ngo-2002. Lo mkhiqizo usuphenduke indinganiso nendinganiso embonini, ngisho nomqondo ofanayo nezixhumi.

U-Shen Qianping, uphothule eNyuvesi yaseStuttgart, eJalimane ngeziqu ze-master engineering kagesi.Usebenze embonini ye-photovoltaic iminyaka eminingi futhi unolwazi olucebile emkhakheni wokuxhuma kagesi.Ujoyine i-Stäubli Group ngo-2009 njengenhloko yokusekelwa kwezobuchwepheshe kumnyango wemikhiqizo ye-photovoltaic.

UShen Qianping uthe izixhumi ze-photovoltaic ezisezingeni eliphansi zingadalaizingozi zomlilo, ikakhulukazi amasistimu asabalalisiwe ophahleni namaphrojekthi we-BIPV.Uma kwenzeka umlilo, ukulahlekelwa kuyoba kukhulu.Entshonalanga yeChina, kunomoya nesihlabathi esiningi, umehluko wezinga lokushisa phakathi kwemini nobusuku mkhulu, futhi amandla emisebe ye-ultraviolet aphakeme kakhulu.Umoya nesihlabathi kuzothinta ukugcinwa kwezitshalo zamandla e-photovoltaic.Izixhumi ezisezingeni eliphansi ziyaguga futhi zikhubazekile.Uma sezihlakaziwe, kuba nzima ukuzifaka futhi.Uphahla olusempumalanga yeChina luneziphephetha-moya, imibhoshongo yokupholisa, oshimula nezinye izinto ezingcolisa umoya, kanye nesimo sezulu esifutha ngosawoti ngasolwandle kanye ne-ammonia ekhiqizwa izimboni zokuhlanza amanzi angcolile, ezizocekela phansi uhlelo, futhiimikhiqizo yesixhumi esisezingeni eliphansi inokumelana nokugqwala okuphansi kusawoti kanye ne-alkali.

Ngaphezu kwekhwalithi yesixhumi se-photovoltaic ngokwayo, enye inkinga ezodala izingozi ezifihliwe ekusebenzeni kwesiteshi samandlaukufakwa okuxubile kwezixhumi zemikhiqizo ehlukene.Enkambweni yokwakhiwa kwesistimu ye-photovoltaic, ngokuvamile kudingekile ukuthenga izixhumi ze-photovoltaic ngokwehlukana ukuze uqaphele ukuxhumeka kwentambo yemojula ebhokisini lokuhlanganisa.Lokhu kuzobandakanya ukuxhumana phakathi kwesixhumi esithengiwe nesixhumi semojula uqobo, futhi ngenxa yeimininingwane, ubukhulu kanye nokubekezelelananezinye izici, izixhumi zemikhiqizo ehlukene azikwazi ukumataniswa kahle, futhiukumelana nokuxhumana kukhulu futhi akuzinzile, okuzothinta kakhulu ukuphepha nokusebenza kahle kokukhiqizwa kwamandla kwesistimu, futhi kunzima ukuthola umenzi ukuthi abhekane nezingozi zekhwalithi.

Isibalo esilandelayo sibonisa ukukhuphuka kwezinga lokushisa lokuxhumana nokumelana okutholwe ngemuva kwe-TUV exutshwe nezixhumi ezifakiwe zemikhiqizo ehlukene, bese ihlolwa i-TC200 ne-DH1000.Okubizwa nge-TC200 kubhekisela ekuhlolweni komjikelezo wokushisa okuphezulu nokuphansi, ebangeni lokushisa lika -35 ℃ kuya ku-+85 ℃, kwenziwa izivivinyo zomjikelezo wama-200.Futhi i-DH1000 ibhekisela ekuhlolweni kokushisa okumanzi, okuhlala amahora angu-1000 ngaphansi kwezinga lokushisa eliphezulu nezimo eziphezulu zomswakama.

 Ukuqhathanisa kokushisisa kwesixhumi (kwesokunxele: izinga lokushisa elikhuphukayo lesixhumi esifanayo; kwesokudla: ukukhuphuka kwezinga lokushisa kwezixhumi zemikhiqizo ehlukene)

Esivivinyweni sokwenyuka kwezinga lokushisa, izixhumi zemikhiqizo ehlukene zixhunywa kwelinye, futhi ukukhuphuka kwezinga lokushisa ngokusobala kukhulu kunebanga lokushisa elivumelekile.

(Ukumelana nokuxhumana ngaphansi kokufakwa okuxubile kwezixhumi zemikhiqizo ehlukene)

Ngokumelana nokuxhumana, uma kungekho zimo zokuhlola ezisetshenziswayo, ayikho inkinga ngezixhumi zemikhiqizo ehlukene ezixhumene zodwa.Nokho, ekuhlolweni kweqembu le-D (ukuhlolwa kokuzivumelanisa nemvelo), izixhumi zomkhiqizo ofanayo nemodeli zigcina ukusebenza okuzinzile, kuyilaphoukusebenza kwezixhumi zemikhiqizo ehlukene kuyehluka kakhulu.

Ezixhunyweni zemikhiqizo ehlukene exhumeke kwenye, ileveli yayo yokuvikela i-IP inzima kakhulu ukuyiqinisekisa.Esinye sezizathu eziyinhloko ukuthiukubekezelelana kwemikhiqizo ehlukene yezixhumi kuhlukile.

Ngisho noma izixhumi zemikhiqizo ehlukene zingafaniswa uma zifakiwe, kusazoba khona ukudonsa, ukukhwehlela, nokokusebenza (amagobolondo avikelayo, izindandatho zokuvala, njll.) imiphumela yokungcolisana.Lokhu ngeke kuhlangabezane nezidingo ezijwayelekile futhi kuzodala izinkinga ekuhlolweni.

Imiphumela yokufakwa okuxubile kwezixhumi zemikhiqizo ehlukene:izintambo ezixegayo;ukwanda okuphawulekayo kwezinga lokushisa likhuphuka futhi kuholela engozini yomlilo;ukuwohloka kwesixhumi kuholela ekushintsheni kokugeleza komoya kanye nebanga elinyakazayo, okuholela engozini yokuchofoza.

Ezitshalweni zamanje zamandla e-photovoltaic, ukwenzeka kokuxhunywa phakathi kwezixhumi zemikhiqizo ehlukene kusengabonakala.Lolu hlobo lomsebenzi olungalungile ngeke lubangele ubungozi bobuchwepheshe kuphela kodwa futhi nezingxabano zomthetho.Ngaphezu kwalokho, ngenxa yokuthi imithetho efanelekile namanje ayiphelele, isifaki sesiteshi samandla se-photovoltaic sizoba nesibopho sezinkinga ezibangelwa ukufakwa okuhlangene kwemikhiqizo ehlukene yezixhumi.

Njengamanje, ukuqashelwa “kokuxhumanisa” (noma “okuhambisanayo”) kwezixhumi kukhawulelwe ekusetshenzisweni kochungechunge olufanayo lwemikhiqizo ekhiqizwe umkhiqizi womkhiqizo ofanayo (kanye nesisekelo sayo).Ngisho noma kukhona izinguquko, i-Foundry ngayinye izokwaziswa ukuze yenze izinguquko ezivumelanisiwe.Imiphumela yamanje yemakethe yokuhlolwa kwezixhumi zemikhiqizo ehlukene efakwe ngokuhlanganyela, ibonisa kuphela isimo samasampuli okuhlola ngalesi sikhathi.Nokho, lo mphumela awusona isitifiketi esifakazela ukufaneleka kwesikhathi eside kwezixhumi ze-interplug.

Ngokusobala, ukumelana nokuxhumana kwezixhumi zemikhiqizo ehlukene akuzinzile kakhulu, ikakhulukazi ukuzinza kwayo isikhathi eside kunzima ukuqinisekiswa, futhi ukushisa kukhulu, okungase kubangele umlilo esimweni esibi kakhulu.

Mayelana nalokhu, izinhlangano zokuhlola ezigunyaziwe i-TUV ne-UL zikhiphe izitatimende ezibhaliwe ezithiabasekeli ukusetshenziswa kwezixhumi zemikhiqizo ehlukene.Ikakhulukazi e-Australia, kuyimpoqo ukungavumeli ukuziphatha kokufakwa kwesixhumi esixubile.Ngakho-ke, isixhumi esithengwe ngokwehlukana kuphrojekthi kumele sibe yimodeli efanayo nesixhumi engxenyeni, noma uchungechunge olufanayo lwemikhiqizo yomkhiqizi ofanayo.

Ukwengeza, isixhumi se-photovoltaic kumojula ngokuvamile sifakwe umkhiqizi webhokisi le-junction ngokusebenzisa imishini ezenzakalelayo, futhi iphrojekthi yokuhlola iphelile, ngakho ikhwalithi yokufaka ithembekile.Kodwa-ke, endaweni yephrojekthi, ukuxhumana phakathi kweyunithi yezinhlamvu zemojuli nebhokisi lesihlanganisi ngokuvamile kudinga ukufakwa ngesandla ngabasebenzi.Ngokwezilinganiso, okungenani amasethi angu-200 ezixhumi ze-photovoltaic kufanele afakwe ngesandla kusistimu ye-photovoltaic ye-megawatt ngayinye.Njengoba ikhwalithi yobungcweti yethimba lamanje lobunjiniyela bokufakwa kwesistimu ye-photovoltaic ngokuvamile liphansi, amathuluzi okufaka asetshenziswayo awawona umsebenzi, futhi ayikho indlela enhle yokuhlola ikhwalithi yokufaka, ikhwalithi yokufaka isixhumi esizeni sephrojekthi ngokuvamile ayilungile, okuba yikhwalithi. Uhlelo lwe-photovoltaic Iphuzu elibuthakathaka.

Isizathu esenza i-MC4 ithandwe imakethe ukuthi ngaphezu kokukhiqizwa kwekhwalithi ephezulu, iphinde ihlanganise ilungelo lobunikazi lika-Stäubli:Ubuchwepheshe be-Multilam.Ubuchwepheshe be-Multilam ngokuyinhloko ukwengeza i-shrapnel yensimbi ekhethekile emise okwebhande phakathi kwezixhumi zesixhumi zesilisa nesifazane, esikhundleni sendawo yokuxhumana engavamile, ikhulise kakhulu indawo yokuxhumana ephumelelayo, yakha isekethe efanayo efanayo, futhi ibe nomthamo omkhulu wamanje wokuthwala. , Ukulahlekelwa kwamandla kanye nokumelana okuncane kokuxhumana, ukumelana nomthelela, ukumelana nokugqwala nokumelana nokushisa okuphezulu, futhi kungagcina ukusebenza okunjalo isikhathi eside.

Izixhumi ze-Photovoltaic ziyingxenye ebalulekile yokuxhumana kwangaphakathi kwezinhlelo zokukhiqiza amandla e-photovoltaic, hhayi kuphela ngamanani amakhulu, kodwa futhi kuhlanganisa nezinye izingxenye.Ngenxa yekhwalithi yomkhiqizo ngokwawo kanye nekhwalithi yokufaka, uma kuqhathaniswa nezinye izingxenye, izixhumi ze-photovoltaic ziwumthombo ovame kakhulu wokuhluleka kwesistimu, futhi zinomthelela obalulekile ekusebenzeni kahle kokukhiqizwa kwamandla kanye nezinzuzo zezomnotho zalo lonke uhlelo.Ngakho-ke,isixhumi se-photovoltaic esikhethiwe kufanele sibe nokumelana okuphansi kakhulu kokuxhumana, futhi singagcina ukumelana nokuxhumana okuphansi isikhathi eside.Ngokwesibonelo, iI-Slocable mc4 isixhumiinokumelana nokuxhumana okungu-0.5mΩ kuphela futhi ingagcina ukumelana nokuxhumana okuphansi isikhathi eside.
