AB  - Bu çalışmada, Zn katklı CuOince filmleri hazırlanarak Al-p-Si/Zn katkılı CuO/Al fotodiyotlarıüretilmiştir. Üretilen fotodiyotların akım-voltaj (I–V) ölçümleri karanlıkta ve farklı aydınlatma şiddetleri altındaalınmıştır. Al-p-Si/Zn katkılı CuO/Alfotodiyotları iyi bir doğrultma ve iyi bir fototepki özelliği göstermiştir. %0.1 Znkatkılı diyotunun en yüksek doğrultma oranına (1.73x104) ve enyüksek fototepki’ye (2.07x103) sahip olduğu saptanmıştır. Frekansabağlı kapasite-voltaj ölçümleri oda sıcaklığında 10kHz ile 1MHz aralığındayapılmıştır. Diyotların kapasitansının, artan frekans ile azalması, arayüz yükdağılımından kaynaklanmaktadır. Anlık fotoakım ölçümleri, diyotlarınfotoiletkenlik davranış sergilediğini gösterir.Zn katkılı CuO filmlerin optiksel özellikleri de UV-VIS spektroskopisiile incelenmiş ve optik enerji bant aralığı 1.89-2.15 eV aralığındabulunmuştur. Filmlerin morfolojik yüzey özellikleri atomik güç mikroskobu (AFM)ile araştırılmıştır. Filmlerin yüzey morfolojisi Zn katkısına bağlı olarakdeğişmiştir. Elde edilen sonuçlar, Al/p-Si/Zn:CuO/Al diyotlarının güneş izlemesistemlerinde fotosensör olarak kullanılabileceğini göstermiştir.
