Nyias-film solar cells ib txwm yog kev lag luam kev tshawb fawb hotspot, ntau qhov kev hloov pauv tau tuaj yeem ncav cuag ntau dua 20% ntawm cov khoom siv roj teeb nyias nyias, suav nrog cadmium telluride (CdTe) cov roj teeb nyias nyias thiab tooj liab indium gallium selenide (CICS, Cu, Hauv, Ga, Se abbreviation) nyias-zaj duab xis roj teeb, lwm yam ntawm cov khoom lag luam yog nyias. chalcogenide roj teeb tau suav hais tias yog ib qho tseem ceeb ntawm cov thev naus laus zis tshiab, cia peb qhia CdTe cov roj teeb nyias nyias.
CdTe yog ib tug ncaj bandgap semiconductor nrog lub siab nqus coefficient ntawm lub hnub ci thiab txwv tsis pub bandwidth ntawm 1.5eV, uas yog qhov zoo rau absorbing lub hnub ci spectrum nto. CdTe tsuas yog xav tau tsawg dua 3um zaj duab xis tuab kom nqus lub teeb kom zoo, uas yog qis dua li 150 ~ 180pm thickness ntawm crystalline silicon, txuag cov ntaub ntawv.
TCO zaj duab xis thiab hlau tiv thaiv txheej yog tso los ntawm CVD thiab PVD. Lub teeb-absorbing CdTe zaj duab xis yog tso los ntawm evaporation plating, sputtering thiab electrochemical deposition. Muaj evaporation plating txoj kev yog ntau dua, muaj ob lub ntsiab evaporation plating txoj kev yog ob: nqaim qhov chaw sublimation txoj kev thiab roj theem thauj deposition.
