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.
