Iiphaneli zelanga

Iseli yelanga, ekwabizwa ngokuba yi "solar chip" okanye "photovoltaic cell", lishiti le-optoelectronic semiconductor elisebenzisa ukukhanya kwelanga ukuvelisa umbane ngokuthe ngqo.Iiseli zelanga enye ayinakusetyenziswa ngokuthe ngqo njengomthombo wamandla.Njengomthombo wamandla, iiseli ezininzi zelanga enye kufuneka zidityaniswe kuthotho, ziqhagamshelwe ngokufana kwaye zipakishwe ngokuqinileyo kumacandelo.

Iphaneli yelanga (ekwabizwa ngokuba yimodyuli yeeseli zelanga) yindibano yeeseli ezininzi zelanga ezidityanisiweyo, eziyinxalenye engundoqo yenkqubo yokuvelisa amandla elanga kunye neyona nxalenye ibalulekileyo yenkqubo yokuvelisa amandla elanga.

Ukuhlelwa

Iphaneli yelanga ye-silicon ye-Monocrystalline

Ukusebenza kokuguqulwa kwe-photoelectric ye-monocrystalline silicon iipaneli zelanga malunga ne-15%, kwaye iphakamileyo yi-24%, eyona nto iphezulu yokuguqula i-photoelectric yokuguqulwa kokusebenza kakuhle kwazo zonke iintlobo zeepaneli zelanga, kodwa iindleko zokuvelisa ziphezulu kangangokuthi azikwazi ukusetyenziswa ngokubanzi kwiindawo ezinkulu. izixa.esetyenzisiweyo.Ekubeni i-silicon ye-monocrystalline ngokubanzi ifakwe kwiglasi epholileyo kunye ne-resin engenamanzi, yomelele kwaye yomelele, kwaye ubomi bayo benkonzo buhlala bufikelela kwiminyaka eyi-15, ukuya kuma-25 eminyaka.

Iphaneli yeSolar ye-Polycrystalline Silicon

Inkqubo yokuvelisa i-polycrystalline silicon solar panels iyafana naleyo ye-monocrystalline silicon solar panels, kodwa i-photoelectric conversion performance ye-polycrystalline silicon solar panels iphantsi kakhulu, kwaye i-photoelectric conversion performance imalunga ne-12% (ngoJulayi 1, 2004, ukusebenza kakuhle). kuluhlu lukaSharp eJapan lwaluyi-14.8%).ezona paneli zelanga ze-polycrystalline zesilicon ezisebenza kakhulu kwihlabathi).Ngokwexabiso lemveliso, lixabiso eliphantsi kuneepaneli zelanga ze-silicon ze-monocrystalline, izinto eziphathekayo zilula ukwenza, ukusetyenziswa kwamandla kugcinwa, kwaye ixabiso elipheleleyo lokuvelisa liphantsi, ngoko liphuhliswe kakhulu.Ukongeza, ubomi benkonzo yeepaneli zelanga ze-polycrystalline silicon bufutshane kunobo be-monocrystalline silicon solar panels.Ngokubhekiselele ekusebenzeni kweendleko, iiphaneli zelanga ze-silicon ze-monocrystalline zingcono kancinci.

Iphaneli yelanga yeAmorphous Silicon

Iphaneli yelanga ye-amorphous silicon luhlobo olutsha lwepaneli yelanga yefilimu enqabileyo ebonakala kwi-1976. Ihluke ngokupheleleyo kwindlela yokuvelisa i-silicon ye-monocrystalline kunye ne-polycrystalline silicon solar panels.Inkqubo yenziwe lula kakhulu, ukusetyenziswa kwezinto ze-silicon kuncinci kakhulu, kwaye ukusetyenziswa kwamandla kuphantsi.Inzuzo ephambili kukuba inokuvelisa umbane nakwiimeko eziphantsi zokukhanya.Nangona kunjalo, ingxaki ephambili yeepaneli zelanga ze-amorphous silicon kukuba ukuguqulwa kwe-photoelectric ukusebenza kakuhle kuphantsi, inqanaba eliphezulu lamazwe ngamazwe li malunga ne-10%, kwaye alizinzile ngokwaneleyo.Ngokwandiswa kwexesha, ukusebenza kakuhle kokuguqulwa kwayo kuyehla.

Multi-compound solar panel

Ii-multi-compound solar panels zibhekisela kwiipaneli zelanga ezingenziwanga ngezixhobo ze-semiconductor enye.Kukho iintlobo ezininzi zophando kumazwe ahlukeneyo, uninzi lwawo angakhange aphuhliswe, ingakumbi kubandakanywa oku kulandelayo:

a) Iiphaneli zelanga zeCadmium sulfide

b) Iphaneli yelanga yeGaAs

c) Copper indium selenide solar panel
