Ag/Azure A /n-Si Schottky Diyodun elektriksel ve fotovoltaik özelliklerinin araştırılması

Abstract

Bu çalışmada; Ag/Azure A/n-Si/Al Schottky diyodların oda sıcaklığında karanlıkta ve solar simülatörde elektriksel ve fotovoltaik özellikleri araştırıldı. Hesaplamaların sonucunda karanlıkta idealite faktörü ve engel yüksekliği I-V ölçümlerinden 1,79, 0,79 eV olarak elde edildi. Fotovoltaik parametreler 100 mW/cm² ışınım altında Voc =162 mV, Isc = 1,47 10^-6 µA, fill faktörü (FF) % 30 ve verim (η) % 4,09 olarak hesaplanmıştır. Sonuçlardan görüleceği üzere imal edilen diyodun fotovoltaik özelliği olmakla beraber verimleri düşük çıkmıştır. Ayrıca I-V ölçümlerinden elde edilen sonuçlara bakıldığında diyodun iyi bir doğrultma özelliğine sahip olduğu söylenebilir.
