Masero ezuva akaonda-firimu agara ari indasitiri yekutsvagisa hotspot, akati wandei ekushandura anogona kusvika kupfuura makumi maviri muzana ehutete-firimu bhatiri tekinoroji, kusanganisira cadmium telluride (CdTe) nhete-firimu bhatiri uye mhangura indium gallium selenide (CICS, Cu, In, Ga, Se abbreviation) bhatiri refirimu, rinotora imwe chikamu chebhatiri rakatetepa. kuti ive yakakosha-inotevera-chizvarwa tekinoroji, ngatiunze iyo CdTe yakaonda-firimu mabhatiri.
CdTe ndeye yakananga bandgap semiconductor ine yakakwira kunyura coefficient yechiedza chezuva uye inorambidzwa bandwidth ye1.5eV, iyo inokodzera kutora pamusoro pesolar spectrum. CdTe inongoda isingasviki 3um firimu ukobvu kuti itore mwenje zvinobudirira, iyo yakadzikira kupfuura iyo 150 ~ 180pm ukobvu hwecrystalline silicon, kuchengetedza zvinhu.
Iyo TCO firimu uye simbi yekusangana layer inoiswa neCVD nePVD. Mafirimu eCdTe anonwisa chiedza anoiswa ne evaporation plating, sputtering uye electrochemical deposition. Maindasitiri evaporation plating nzira yakajairika, kune maviri makuru evaporation eplating nzira mbiri: nhete nzvimbo sublimation nzira uye gasi chikamu chekufambisa deposition.
