Sirin-fim hasken rana Kwayoyin sun kasance koyaushe wurin bincike na masana'antu, ingantaccen juzu'i da yawa na iya kaiwa sama da kashi 20% na fasahar batirin sirara-fim, gami da batir cadmium telluride (CdTe) batir na bakin ciki da batir indium gallium selenide (CICS, Cu, In, Ga, Se ragewa) batir na fim na bakin ciki, kasuwa yana mamaye wasu siraran batirin. ana ɗauka a matsayin fasaha mai mahimmanci na zamani na gaba, bari mu gabatar da batura na bakin ciki na CdTe.
CdTe shine semiconductor bandgap kai tsaye tare da babban adadin hasken rana da kuma haramtaccen bandwidth na 1.5eV, wanda ya dace don ɗaukar bakan hasken rana. CdTe kawai yana buƙatar ƙasa da kauri na fim na 3um don ɗaukar haske yadda ya kamata, wanda yake ƙasa da ƙasa da kauri na 150 ~ 180pm na silicon crystalline, kayan ceto.
Ana ajiye fim ɗin TCO da Layer lamba na ƙarfe ta CVD da PVD. Fina-finan CdTe masu ɗaukar haske ana ajiye su ta hanyar zubar da evaporation plating, sputtering da electrochemical. Masana'antu evaporation plating Hanyar ne mafi na kowa, akwai biyu main evaporation plating hanyoyin biyu: kunkuntar sarari sublimation Hanyar da gas lokaci kai ajiya.
