iiseli zelanga ziye zaphuhliswa kwisizukulwana sesithathu, isizukulwana sokuqala i-monocrystalline silicon iiseli zelanga, isizukulwana sesibini yi-silicon ye-amorphous kunye neeseli ze-silicon ze-polycrystalline, kwaye isizukulwana sesithathu yi-copper-steel-gallium-selenide (CIGS) njengommeli wefilimu encinci yeeseli zelanga.
Ngokutsho kokulungiswa kwebhetri usebenzisa izinto ezahlukeneyo, iiseli zelanga zingahlulwa zibe ngamacandelo alandelayo.
Iiseli zelanga ze-silicon zahlulwe zaba ziiseli zelanga ze-monocrystalline silicon, iiseli zelanga ze-polycrystalline silicon ezibhityileyo kunye neeseli zelanga ze-amorphous ze-silicon ezibhityileyo zeentlobo ezintathu.
Iiseli zelanga ze-silicon ze-Monocrystalline zineyona ndlela iphezulu yokuguqula kunye neyona teknoloji ikhulileyo. Eyona mpumelelo iphezulu yokuguqulwa kwilabhoratri yi-23% yesikali, kwaye ukusebenza kakuhle kwimveliso yi-15%, esalawulayo kwizicelo ezinkulu kunye nemveliso yeshishini. Nangona kunjalo, ngenxa yeendleko eziphezulu ze-silicon ye-monocrystalline, kunzima ukunciphisa kakhulu iindleko zayo, ukuze kugcinwe izinto ze-silicon, ukuphuhliswa kwefilimu encinci ye-silicon yemveliso kunye nefilimu ye-amorphous ye-silicon njengenye indlela kwiiseli zelanga ze-silicon ze-monocrystalline.
Iiseli zelanga ze-polycrystalline ze-silicon ezicwecwe kunye ne-monocrystalline silicon iiseli zelanga zelanga, ixabiso liphantsi, ngelixa ukusebenza kakuhle kuphezulu kune-amorphous silicon ifilimu encinci yeeseli zelanga zelanga, ukuguqulwa okuphezulu kokuguqulwa kwebhubhoratri yayo yi-18%, ukuguqulwa kokusebenza kwemveliso ye-industrial-scale yi-10%. Ke ngoko, iiseli zelanga ze-polycrystalline zesilicon ezicekethekileyo ziya kulawula ngokukhawuleza imarike yeeseli zelanga.
I-silicon ye-amorphous ifilimu encinci yeeseli zelanga zinexabiso eliphantsi, ubunzima obulula, ukusebenza kakuhle kokuguqulwa, kulula ukuvelisa ubuninzi, inamandla amakhulu. Nangona kunjalo, ukunyanzelwa yimpembelelo ye-photoelectric-induced ye-photoelectric effect yokwehla, uzinzo aluphezulu, luchaphazela ngokuthe ngqo usetyenziso lwalo. Ukuba sinokuqhubeka sisombulula ingxaki yozinzo kunye nokuphucula izinga lokuguqulwa, ngoko iiseli ze-amorphous silicon zelanga ngokungangabazeki ziluphuhliso oluphambili lweeseli zelanga zemveliso!
(2) Iiseli zelanga zelanga ezineembumba ezininzi ezicekethekileyo
Multi-compound ifilimu obhityileyo izixhobo zeseli solar iityuwa inorganic, kubandakanywa iikhompawundi gallium arsenide, cadmium sulfide, cadmium sulfide kunye nobhedu entolongweni selenium iibhetri film obhityileyo.
I-Cadmium sulfide, i-cadmium telluride polycrystalline ebhityileyo-ifilimu yesolar esebenza kakuhle iphezulu kune-non-pin ye-silicon ecwengileyo yeeseli zelanga zelanga, ixabiso lingaphantsi kune-monocrystalline silicon iiseli zelanga zelanga, kwaye kulula nokuveliswa kwemveliso enkulu, kodwa ngenxa ye-cadmium inetyhefu ephezulu, iya kubangela ukungcoliseka okunzulu kokusingqongileyo, ngoko ke i-silicon ayifanelekanga.
