I-solar panel ingenye yezingxenye ezibaluleke kakhulu ohlelweni lokuphehla amandla elanga.Umsebenzi wawo ukuguqula amandla elanga abe amandla kagesi, bese ukhipha ugesi we-DC ukuze ugcinwe ebhethri.Izinga layo lokuguqulwa nempilo yesevisi yizici ezibalulekile zokunquma ukuthi iseli lelanga linenani lokusetshenziswa.
Amaseli elanga ahlanganiswe nokusebenza kahle okuphezulu (ngaphezu kwe-21%) amaseli elanga e-silicon e-monocrystalline ukuze kuqinisekiswe amandla anele akhiqizwa ama-solar panel.Ingilazi yenziwe ngengilazi ye-suede yensimbi ephansi (eyaziwa nangokuthi ingilazi emhlophe), enokudlulisa okungaphezu kuka-91% phakathi kobubanzi be-wavelength bokusabela kwe-solar cell spectral, futhi inokukhanya okuphezulu kokukhanya kwe-infrared okukhulu kuno-1200 nm.Ngesikhathi esifanayo, ingilazi ingakwazi ukumelana nemisebe yokukhanya kwe-ultraviolet yelanga ngaphandle kokunciphisa ukudlulisa.I-EVA yamukela ifilimu yekhwalithi ephezulu ye-EVA enogqinsi olungu-0.78mm engezwe nge-anti ultraviolet ejenti, i-antioxidant kanye ne-ejenti yokwelapha njenge-ejenti yokuvala amaseli elanga kanye ne-ejenti exhumanisayo phakathi kwengilazi ne-TPT, enekhono eliphezulu lokudlulisela kanye nekhono lokulwa nokuguga.
Isembozo sangemuva se-TPT cell cell - ifilimu ye-fluoroplastic imhlophe, ebonisa ukukhanya kwelanga, ngakho-ke ukusebenza kahle kwemodyuli kuthuthukiswa kancane.Ngenxa yokukhishwa kwayo okuphezulu kwe-infrared, inganciphisa izinga lokushisa lokusebenza kwemojula, futhi ibuye ibe ngcono ekuthuthukiseni ukusebenza kahle kwemojuli.Uhlaka lwe-aluminium alloy olusetshenziselwa ifreyimu lunamandla aphezulu kanye nokumelana nomthelela oqinile wokusebenza.Futhi kuyingxenye ebaluleke kakhulu yesistimu yokuphehla amandla elanga.Umsebenzi wawo ukuguqula umthamo wemisebe yelanga ube amandla kagesi, noma uwuthumele ebhethrini lokugcina ukuze ugcinwe, noma ukhuthaze umsebenzi wokulayisha.
Umgomo Wokusebenza Wephaneli Yelanga
Iphaneli yelanga iyisisetshenziswa se-semiconductor esingaguqula ngokuqondile amandla okukhanya abe amandla kagesi.Isakhiwo sayo esiyisisekelo sakhiwe i-semiconductor PN junction.Ukuthatha i-silicon PN cell cell ejwayelekile kakhulu njengesibonelo, ukuguqulwa kwamandla okukhanya abe amandla kagesi kuxoxwa ngokuningiliziwe.
Njengoba sonke sazi, izinto ezinenani elikhulu lezinhlayiya ezihamba mahhala ezihambayo futhi okulula ukuziqhuba zamanje zibizwa ngokuthi ama-conductor.Ngokuvamile, izinsimbi ziyi-conductor.Isibonelo, ukuqhutshwa kwethusi cishe ku-106/(Ω. cm).Uma i-voltage engu-1V isetshenziswa ezindaweni ezimbili ezihambisanayo ze-cube yethusi engu-1cm x 1cm x 1cm, i-current ye-106A izogeleza phakathi kwezindawo ezimbili.Ngakolunye uhlangothi kukhona izinto okunzima kakhulu ukuqhuba zamanje, ezibizwa ngokuthi ama-insulators, njenge-ceramics, i-mica, igrisi, irabha, njll. Isibonelo, ukuqhutshwa kwe-quartz (SiO2) cishe ku-10-16/(Ω. cm) .I-semiconductor ine-conductivity phakathi kwe-conductor ne-insulator.I-conductivity yayo ingu-10-4~104/(Ω. cm).I-semiconductor ingashintsha ukuqhutshwa kwayo ebangeni elingenhla ngokungeza inani elincane lokungcola.I-conductivity ye-semiconductor ehlanzekile ngokwanele izokhuphuka kakhulu ngokukhuphuka kwezinga lokushisa.
Ama-semiconductors angaba izakhi, njenge-silicon (Si), i-germanium (Ge), i-selenium (Se), njll;Kungase futhi kube inhlanganisela, njenge-cadmium sulfide (Cds), i-gallium arsenide (GaAs), njll;Kungase futhi kube ingxubevange, njenge-Ga, AL1~XAs, lapho u-x eyinoma iyiphi inombolo phakathi kuka-0 no-1. Izici eziningi zikagesi zama-semiconductors zingachazwa ngemodeli elula.Inombolo ye-athomu ye-silicon yi-14, ngakho-ke kukhona ama-electron angu-14 ngaphandle kwe-nucleus ye-athomu.Phakathi kwazo, ama-electron angu-10 ongqimbeni lwangaphakathi aboshwe ngokuqinile yi-nucleus ye-athomu, kuyilapho ama-electron angu-4 oqweqwe lwangaphandle eboshwe kancane yi-nucleus ye-athomu.Uma amandla anele atholakala, angahlukaniswa ne-nucleus ye-athomu futhi abe ama-electron mahhala, ashiye imbobo endaweni yokuqala ngesikhathi esifanayo.Ama-electron ashajwe kabi futhi izimbobo zishajwe kahle.Ama-electron amane ongqimbeni lwangaphandle lwe-silicon nucleus abizwa nangokuthi ama-electron e-valence.
Ku-silicon crystal, kunama-athomu amane aseduze azungeze i-athomu ngayinye nama-electron amabili e-valence ane-athomu ngayinye eseduze, akha igobolondo le-athomu elingu-8 elizinzile.Kuthatha amandla angu-1.12eV ukuhlukanisa i-electron ku-athomu ye-silicon, ebizwa ngokuthi i-silicon band gap.Ama-electron ahlukanisiwe angama-electron conduction mahhala, angahamba ngokukhululekile futhi adlulisele okwamanje.Lapho i-electron iphuma e-athomu, ishiya isikhala, esibizwa ngokuthi imbobo.Ama-electron avela kuma-athomu aseduze angagcwalisa imbobo, enze imbobo isuke endaweni eyodwa iye kwentsha, ngaleyo ndlela yakhe umsinga.I-current ekhiqizwa ukuhamba kwama-electron ilingana neyamanje ekhiqizwayo lapho imbobo ene-positive inyakaza ibheke kolunye uhlangothi.
