Iiseli zelanga ziye zaphuhliswa ukuya kwisizukulwana sesithathu, apho isizukulwana sokuqala ziiseli zelanga ze-silicon ezi-monocrystalline, isizukulwana sesibini ziiseli zelanga ze-silicon ezi-amorphous kunye ne-polycrystalline silicon, kwaye isizukulwana sesithathu yi-copper-steel-gallium-selenide (CIGS) njengommeli weeseli zelanga ezidityanisiweyo zefilimu.
Ngokwendlela ibhetri elungiselelwa ngayo kusetyenziswa izinto ezahlukeneyo, iiseli zelanga zinokwahlulwahlulwa zibe ziindidi ezilandelayo.
Iiseli zelanga zeSilicon zahlulwe zibe ziiseli zelanga zesilicon ezi-monocrystalline, iiseli zelanga zesilicon ezi-polycrystalline kunye neeseli zelanga zesilicon ezi-amorphous ezi-thin-film ze-solar zeentlobo ezintathu.
Iiseli zelanga ze-silicon ezi-monocrystalline zisebenza kakuhle kakhulu ekuguquleni kunye netekhnoloji evuthiweyo. Ukusebenza kakuhle kakhulu ekuguquleni kwilebhu yi-23%, kwaye ukusebenza kakuhle kwimveliso yi-15%, nto leyo esalawulayo kwizicelo ezinkulu nakwimveliso yemizi-mveliso. Nangona kunjalo, ngenxa yexabiso eliphezulu le-silicon e-monocrystalline, kunzima ukunciphisa kakhulu iindleko zayo, ukuze kongiwe izixhobo ze-silicon, uphuhliso lwefilimu e-silicon thin yemveliso emininzi kunye nefilimu e-amorphous silicon thin njengendlela eyahlukileyo kwiiseli zelanga ze-silicon ezi-monocrystalline.
Iiseli zelanga ze-silicon ezibhityileyo ze-polycrystalline kunye neeseli zelanga ze-silicon ezibhityileyo ze-monocrystalline, ixabiso liphantsi, ngelixa ukusebenza kakuhle kuphezulu kuneeseli zelanga ze-silicon ezibhityileyo ze-amorphous, ukusebenza okuphezulu kokuguqulwa kwelebhu yayo yi-18%, ukusebenza kakuhle kokuguqulwa kwemveliso yomgangatho wemizi-mveliso yi-10%. Ke ngoko, iiseli zelanga ze-silicon ezibhityileyo ze-polycrystalline ziya kulawula imarike yeeseli zelanga kungekudala.
Iiseli zelanga ze-silicon ezithambileyo ezi-amorphous zibiza kancinci, zinobunzima obulula, zisebenza kakuhle ekuguquleni, zilula ukuvelisa ngobuninzi, zinamandla amakhulu. Nangona kunjalo, ngenxa yesiphumo sayo sokuwohloka kokusebenza kwe-photoelectric okubangelwa zizinto ezibonakalayo, uzinzo aluphezulu, nto leyo echaphazela ngokuthe ngqo ukusetyenziswa kwayo. Ukuba singasombulula ingxaki yozinzo kwaye siphucule izinga lokuguqulwa, ngoko iiseli zelanga ze-silicon ezi-amorphous ngokuqinisekileyo luphuhliso oluphambili lweeseli zelanga zemveliso!
(2) Iiseli zelanga ezibhityileyo ezineefilimu ezininzi
Izixhobo zeseli zelanga ezibhityileyo ezininzi ezidityanisiweyo zeetyuwa ezingaphiliyo, kuquka iikhompawundi ze-gallium arsenide, i-cadmium sulfide, i-cadmium sulfide kunye neebhetri zefilimu ezibhityileyo zeselenium ezivalelwe ngekopolo.
I-Cadmium sulfide, i-cadmium telluride polycrystalline thin-film solar cells iphezulu kunee-non-pin silicon thin-film solar cells, ixabiso liphantsi kunee-monocrystalline silicon solar cells, kwaye kulula ukuvelisa ngobukhulu, kodwa ngenxa yokuba i-cadmium inetyhefu ephezulu, iya kubangela ungcoliseko olukhulu lwendalo, ngoko ke ayisiyondlela ifanelekileyo kunee-pin body zee-silicon solar cells.
