Cov roj teeb hnub ci nyias nyias yeej ib txwm yog qhov chaw tshawb fawb tseem ceeb hauv kev lag luam, ntau qhov kev hloov pauv tau zoo tuaj yeem ncav cuag ntau dua 20% ntawm cov thev naus laus zis roj teeb nyias nyias, suav nrog cadmium telluride (CdTe) roj teeb nyias nyias thiab tooj liab indium gallium selenide (CICS, Cu, In, Ga, Se luv luv) roj teeb nyias nyias, nyob hauv qee qhov feem ntawm kev ua lag luam, lwm lub roj teeb nyias nyias uas yog roj teeb chalcogenide suav hais tias yog cov thev naus laus zis tseem ceeb rau tiam tom ntej, cia peb qhia txog cov roj teeb nyias nyias CdTe.

CdTe yog ib lub semiconductor bandgap ncaj qha nrog lub zog nqus tau zoo ntawm lub hnub ci thiab bandwidth txwv tsis pub tshaj 1.5 eV, uas zoo rau kev nqus cov spectrum ntawm lub hnub ci. CdTe tsuas yog xav tau tsawg dua 3um zaj duab xis tuab kom nqus tau lub teeb zoo, uas qis dua 150 ~ 180pm tuab ntawm crystalline silicon, txuag cov khoom siv.

Cov zaj duab xis TCO thiab cov txheej hlau sib cuag tau tso los ntawm CVD thiab PVD. Cov zaj duab xis CdTe uas nqus lub teeb tau tso los ntawm kev evaporation plating, sputtering thiab electrochemical deposition. Txoj kev evaporation plating hauv kev lag luam yog qhov siv ntau dua, muaj ob txoj kev evaporation plating tseem ceeb: txoj kev sublimation qhov chaw nqaim thiab txoj kev thauj mus los ntawm cov roj theem.
