Ma cell a solar amtundu wocheperako nthawi zonse amakhala malo opangira kafukufuku wamakampani, kutembenuka kochulukirapo kumatha kufika kupitilira 20% yaukadaulo wamabatire amafilimu, kuphatikiza batri ya cadmium telluride (CdTe) ndi copper indium gallium selenide (CICS, Cu, In, Ga, Se abbreviation) batire laling'ono lafilimu, limakhala ndi gawo lina la batri la batri. kukhala ukadaulo wofunikira wam'badwo wotsatira, tiyeni tidziwitse mabatire a CdTe woonda-filimu.
CdTe ndi semiconductor ya bandgap yomwe imakhala ndi mphamvu yoyamwitsa kwambiri ya dzuwa komanso bandwidth yoletsedwa ya 1.5eV, yomwe ndi yabwino kutengera mawonekedwe a solar. CdTe imangofunika makulidwe a filimu osakwana 3um kuti atenge kuwala bwino, komwe kumakhala kotsika kwambiri kuposa makulidwe a crystalline 150 ~ 180pm, zida zopulumutsira.
Filimu ya TCO ndi wosanjikiza wolumikizana ndi zitsulo zimayikidwa ndi CVD ndi PVD. Mafilimu a CdTe oyamwa kuwala amayikidwa ndi evaporation plating, sputtering ndi electrochemical deposition. Industrial evaporation plating njira ndiyofala kwambiri, pali njira ziwiri zazikulu za evaporation plating ndi ziwiri: njira yopapatiza danga ndi gawo la gasi.
