CdS filmleri, optoelektronikde ve heteroeklem güneş pillerinde kullanılmaktadır. Bu çalışmada, CdS ve In katkılı CdS filmleri (% 2, 8) ultrasonik kimyasal püskürtme tekniğiyle 300±5 C’de cam tabanlar üzerine depolanmıştır. Filmlerin elektriksel özdirençleri dört uç tekniği kullanılarak belirlenmiştir. Filmlerin kalınlıkları ve optik özellikleri spektroskopik elipsometre (SE) cihazı ile incelenmiştir. UV spektrofotometre cihazı ile geçirgenlik ve soğurma spektrumları alınmıştır. Atomik kuvvet mikroskobu (AKM) ile CdS filmlerinin yüzey topografisi üzerine In katkısının etkisi incelenmiştir.
