Iphaneli yelanga yenye yezona zinto zibalulekileyo kwinkqubo yokuvelisa amandla elanga.Umsebenzi wayo kukuguqula amandla elanga kumandla ombane, kwaye emva koko ukhuphe umbane weDC ukugcina kwibhetri.Izinga lokuguqulwa kwayo kunye nobomi benkonzo zizinto ezibalulekileyo zokuqinisekisa ukuba iseli yelanga inexabiso lokusetyenziswa.
Iiseli zelanga zipakishwe nge-high-efficiency (ngaphezulu kwe-21%) iiseli ze-silicon ze-monocrystalline ze-solar ukuqinisekisa ukuba amandla aneleyo aveliswa ngamapaneli elanga.Iglasi yenziwe ngentsimbi esezantsi epholileyo yeglasi yesuede (ekwabizwa ngokuba yiglasi emhlophe), ene-transmittance engaphezu kwe-91% ngaphakathi koluhlu lwamaza okukhanya kweeseli zelanga, kwaye inokukhanya okuphezulu kokukhanya kwe-infrared okungaphezulu kwe-1200 nm.Kwangaxeshanye, iglasi inokumelana nemitha yokukhanya kwe-ultraviolet yelanga ngaphandle kokunciphisa ukuhanjiswa.I-EVA ithatha ifilimu ye-EVA ephezulu kunye nobukhulu be-0.78mm eyongeziweyo kunye ne-anti ultraviolet agent, i-antioxidant kunye ne-ejenti yokunyanga njenge-agent yokutywina kwiiseli zelanga kunye ne-agent edibanisayo phakathi kweglasi kunye ne-TPT, enokudluliselwa okuphezulu kunye nokukwazi ukuguga.
Ikhava yangasemva ye-TPT yeseli yelanga - ifilimu ye-fluoroplastic imhlophe, ebonisa ukukhanya kwelanga, ngoko ke ukusebenza kakuhle kwemodyuli kuphuculwe kancinci.Ngenxa yokukhutshwa kwayo okuphezulu kwe-infrared, inokunciphisa ubushushu bokusebenza bemodyuli, kwaye ikwanceda ekuphuculeni ukusebenza kakuhle kwemodyuli.Isakhelo se-aluminiyam ye-alloy esetyenziselwa isakhelo sinamandla aphezulu kunye nokumelana nefuthe elinamandla lomatshini.Ikwalelona candelo lixabisekileyo lenkqubo yokuvelisa amandla elanga.Umsebenzi wayo kukuguqula amandla emitha yelanga kumandla ombane, okanye ukuyithumela kwibhetri yokugcina ukugcinwa, okanye ukukhuthaza umsebenzi womthwalo.
Umgaqo wokuSebenza wePaneli yeSolar
Iphaneli yelanga sisixhobo semiconductor esinokuguqula ngokuthe ngqo amandla okukhanya abe ngamandla ombane.Isakhiwo sayo esisisiseko senziwe nge-semiconductor PN junction.Ukuthatha i-silicon ye-solar ye-silicon eqhelekileyo njengomzekelo, ukuguqulwa kwamandla okukhanya kumandla ombane kuxoxwa ngokubanzi.
Njengoko sonke sisazi, izinto ezinenani elikhulu lamasuntswana ahlawulelwayo ahamba simahla kwaye kulula ukuqhuba okwangoku zibizwa ngokuba zii-conductor.Ngokuqhelekileyo, isinyithi zi-conductor.Ngokomzekelo, i-conductivity yobhedu malunga ne-106 / (Ω. cm).Ukuba i-voltage ye-1V isetyenziswe kwiindawo ezimbini ezihambelanayo ze-1cm x 1cm x 1cm yetyhubhu yethusi, i-current ye-106A iya kuhamba phakathi kweendawo ezimbini.Kwesinye isiphelo zizinto ezinzima kakhulu ukuqhuba okwangoku, ezibizwa ngokuba yi-insulators, njenge-ceramics, i-mica, igrisi, i-rubber, njl. Umzekelo, ukuqhutyelwa kwe-quartz (SiO2) malunga ne-10-16 / (Ω. cm) .I-semiconductor ine-conductivity phakathi komqhubi kunye ne-insulator.I-conductivity yayo yi-10-4 ~ 104 / (Ω. cm).I-semiconductor inokutshintsha i-conductivity yayo kuluhlu olungentla ngokongeza inani elincinci lokungcola.I-conductivity ye-semiconductor ecocekileyo eyaneleyo iya kunyuka ngokukhawuleza ngokunyuka kweqondo lokushisa.
I-semiconductors ingaba yizinto, ezifana ne-silicon (Si), i-germanium (Ge), i-selenium (Se), njl.Inokuthi ibe yinto edibeneyo, efana ne-cadmium sulfide (i-Cds), i-gallium arsenide (i-GaAs), njl.Isenokuba yi-alloy, njenge-Ga, AL1~XAs, apho x naliphi na inani phakathi kwe-0 kunye ne-1. Iimpawu ezininzi zombane ze-semiconductors zinokuchazwa ngemodeli elula.Inani le-atom le-silicon li-14, ngoko ke kukho ii-electron ezili-14 ngaphandle kwe-nucleus ye-athomu.Phakathi kwazo, ii-electron ezili-10 kumaleko angaphakathi zibotshelelwe ngokuqinileyo yinucleus yeathomu, ngelixa ii-electron ezi-4 kumaleko angaphandle zibotshelelwe ngaphantsi yinucleus yeathomu.Ukuba amandla aneleyo afunyenwe, anokwahlulwa kwi-nucleus ye-athomu kwaye abe ngama-electron akhululekile, ashiye umngxuma kwindawo yokuqala ngexesha elifanayo.Ii-electron zihlawuliswa kakubi kwaye imingxuma ihlanjwe kakuhle.Ii-electron ezine kumaleko angaphandle e-silicon nucleus zikwabizwa ngokuba yi-valence electrons.
Kwikristale yesilicon, kukho iiathom ezine ezikufutshane ezijikeleze iathom nganye kunye nee-elektroni ezimbini ze-valence ezineathom nganye emeleneyo, zenza iqokobhe le-athom ezi-8.Kuthatha amandla e-1.12eV ukwahlula i-electron kwi-athomu ye-silicon, ebizwa ngokuba yi-silicon band gap.Ii-electron ezihlukanisiweyo ziyi-electrons conduction zamahhala, ezinokuhamba ngokukhululekile kwaye zisasaze ngoku.Xa i-electron iphuma kwi-athom, ishiya isithuba, esibizwa ngokuba ngumngxuma.Ii-electron ezisuka kwii-athom ezimeleneyo zinokuzalisa umngxuma, zibangele ukuba umngxuma uhambe ukusuka kwindawo ethile ukuya kwenye, ngaloo ndlela wenze umsinga.Ikhoyo ngoku eveliswa ukuhamba kwee-electron ilingana nokhoyo owenziweyo xa umngxuma ohlanjwe kakuhle uhamba kwicala elichaseneyo.
