Iiseli zelanga ezinefilim ezincinci bezisoloko ziyindawo yophando kushishino, uguqulo olusebenzayo lunokufikelela ngaphezulu kwe-20% yetekhnoloji yebhetri ecekethekileyo, kubandakanya i-cadmium telluride (CdTe) ibhetri yefilim encinci kunye ne-copper indium gallium selenide (CICS, Cu, In, Ga, Sefinyeta) ibhetri yefilim ebhityileyo, ithatha enye ibhetri yefilim ethathwa njengenye ibhetri. ukuze sibe yiteknoloji yesizukulwana esilandelayo esibalulekileyo, masazise iibhetri zefilimu yeCdTe encinci.
I-CdTe yi-direct bandgap semiconductor ene-coefficient yokufunxa ephezulu yokukhanya kwelanga kunye ne-bandwidth engavumelekanga ye-1.5eV, ekulungele ukufunxa i-spectrum yelanga. I-CdTe ifuna kuphela ubungqingqwa befilimu obungaphantsi kwe-3um ukufunxa ukukhanya ngokufanelekileyo, obungaphantsi kakhulu kunobungqingqwa be-silicon yekristale eyi-150 ~ 180pm, izixhobo zokonga.
Ifilimu ye-TCO kunye ne-metal contact layer ifakwe kwi-CVD kunye ne-PVD. Iifilim ze-CdTe ezifunxa ukukhanya zifakwe kwiplating ephuphumayo, i-sputtering kunye ne-electrochemical deposition. Indlela yokufaka umphunga kwimizi-mveliso ixhaphake kakhulu, zimbini iindlela zokubeka umphunga ezingundoqo zimbini: indlela emxinwa yendawo yokuthotywa kwe-sublimation kunye nesigaba sothutho segesi.
