Ukadaulo wopaka utoto mu maselo a dzuwa a CdTe

Maselo a dzuwa opyapyala akhala malo ofufuzira kwambiri mumakampaniwa, magwiridwe antchito angapo osinthira mphamvu amatha kufikira 20% ya ukadaulo wa batri wopyapyala, kuphatikiza batri wopyapyala wa cadmium telluride (CdTe) ndi batri wopyapyala wa copper indium gallium selenide (CICS, Cu, In, Ga, Se abbreviation) wopyapyala wa copper indium gallium selenide (CICS, Cu, In, Ga, Se abbreviation), womwe uli ndi gawo lina pamsika, batri lina lopyapyala lomwe ndi batri la chalcogenide limaonedwa kuti ndi ukadaulo wofunikira wa m'badwo wotsatira, tiyeni tiyambe ndi mabatire opyapyala a CdTe.

CdTe ndi semiconductor yolunjika yokhala ndi bandgap yokhala ndi mphamvu yayikulu yoyamwa kwa dzuwa komanso bandwidth yoletsedwa ya 1.5eV, yomwe ndi yabwino kuyamwa mawonekedwe a solar spectrum pamwamba. CdTe imangofunika makulidwe osakwana 3um film kuti inyamule kuwala bwino, komwe kuli kotsika kwambiri kuposa makulidwe a crystalline silicon a 150 ~ 180pm, kusunga zinthu.

Filimu ya TCO ndi gawo lolumikizirana ndi zitsulo zimayikidwa ndi CVD ndi PVD. Mafilimu a CdTe opepuka amayikidwa ndi evaporation plating, sputtering ndi electrochemical deposition. Njira yopangira evaporation plating ya mafakitale ndi yofala kwambiri, pali njira ziwiri zazikulu zopangira evaporation plating ndi ziwiri: njira yopapatiza sublimation ndi gas phase transport deposition.
