Amaphaneli elanga

Iseli yelanga, eyaziwa nangokuthi "i-solar chip" noma "photovoltaic cell", iyishidi le-optoelectronic semiconductor elisebenzisa ukukhanya kwelanga ukukhiqiza ugesi ngokuqondile.Amaseli elanga elilodwa awakwazi ukusetshenziswa ngokuqondile njengomthombo wamandla.Njengomthombo wamandla, amaseli amaningana elanga elilodwa kufanele axhunywe ochungechungeni, axhunywe ngokuhambisana futhi ahlanganiswe ngokuqinile abe yizingxenye.

Iphaneli yelanga (ebuye ibizwe ngokuthi imojula yeseli yelanga) iwukuhlanganiswa kwamaseli elanga amaningi ahlanganisiwe, okuyingxenye eyinhloko yesistimu yokuphehla amandla elanga kanye nengxenye ebaluleke kakhulu yesistimu yokuphehla amandla elanga.

Ukwahlukanisa

Iphaneli yelanga ye-silicon ye-Monocrystalline

Ukusebenza kahle kokuguqulwa kwesithombe sikagesi we-monocrystalline silicon solar panels kumayelana ne-15%, futhi ephakeme kakhulu yi-24%, okuyindlela ephakeme kakhulu yokuguqulwa kwesithombe sikagesi kuzo zonke izinhlobo zamaphaneli elanga, kodwa izindleko zokukhiqiza ziphezulu kangangokuthi azikwazi ukusetshenziswa kabanzi ezindaweni ezinkulu. amanani.esetshenzisiwe.Njengoba i-silicon ye-monocrystalline ngokuvamile imbozwa ngengilazi epholile kanye ne-resin engangeni manzi, iqinile futhi ihlala isikhathi eside, futhi impilo yayo yesevisi ngokuvamile ifinyelela eminyakeni engu-15, kuze kufike eminyakeni engu-25.

I-Polycrystalline Silicon Solar Panel

Inqubo yokukhiqiza yamaphaneli elanga e-polycrystalline silicon iyafana naleyo yamaphaneli elanga e-monocrystalline silicon, kodwa ukusebenza kahle kokuguqulwa kwe-photoelectric kwamaphaneli elanga e-polycrystalline silicon kuphansi kakhulu, futhi ukusebenza kahle kokuguqulwa kwe-photoelectric kucishe kube yi-12% (ngoJulayi 1, 2004, ukusebenza kahle). ohlwini lwe-Sharp e-Japan yayingu-14.8%).amaphaneli elanga e-polycrystalline silicon asebenza kahle kakhulu emhlabeni).Mayelana nezindleko zokukhiqiza, ishibhile kunamaphaneli elanga e-monocrystalline silicon, impahla ilula ukwenza, ukusetshenziswa kwamandla kugcinwa, futhi izindleko zokukhiqiza eziphelele ziphansi, ngakho-ke iye yathuthukiswa kakhulu.Ngaphezu kwalokho, impilo yesevisi yamaphaneli elanga e-polycrystalline silicon nayo imfushane kunaleyo yamaphaneli elanga e-monocrystalline silicon.Mayelana nokusebenza kwezindleko, amaphaneli elanga e-monocrystalline silicon angcono kancane.

I-Amorphous Silicon Solar Panel

I-amorphous silicon solar panel iwuhlobo olusha lwephaneli yelanga elincane lefilimu elavela ngo-1976. Ihluke ngokuphelele endleleni yokukhiqiza ye-silicon ye-monocrystalline kanye ne-polycrystalline silicon solar panels.Inqubo yenziwa lula kakhulu, ukusetshenziswa kwezinto ze-silicon kuncane kakhulu, futhi ukusetshenziswa kwamandla kuphansi.Inzuzo enkulu ukuthi ingakwazi ukukhiqiza ugesi ngisho nasezimweni eziphansi zokukhanya.Kodwa-ke, inkinga enkulu yamaphaneli elanga e-amorphous silicon ukuthi ukusebenza kahle kokuguqulwa kwe-photoelectric kuphansi, izinga elithuthukile lamazwe ngamazwe limayelana ne-10%, futhi alizinzile ngokwanele.Ngokunwetshwa kwesikhathi, ukusebenza kahle kokuguqulwa kwayo kuyehla.

Iphaneli yelanga enezinhlanganisela eziningi

Amaphaneli elanga anenhlanganisela eminingi abhekisela kumaphaneli elanga angenziwanga ngezinto ezisetshenziswa yi-semiconductor ye-single-element.Kunezinhlobo eziningi zocwaningo emazweni ahlukahlukene, iningi lawo elingakenziwa izimboni, ikakhulukazi okuhlanganisa okulandelayo:

a) Amaphaneli elanga e-Cadmium sulfide

b) Iphaneli yelanga ye-GaAs

c) Iphaneli yelanga ye-Copper indium selenide
