“…In last years, electrical and optical properties of metal/ semiconductor (MS) contacts which are composed of an organic or polymer interlayer, have been investigated as a function of illumination in detail instead of insulator or oxide interlayer because they let modify electrical parameters of them such as ideality factor (n), series/shunt resistances (R s , R sh ), saturation current (I s or I 0 ), barrier height (BH), rectification rate (RR), interface/surface states (N ss ), photosensitivity (S), open-circuit voltage (V oc ). [1][2][3][4][5][6][7][8][9] All these parameters are usually dependent on the homogeneity of BH, formed interlayer between MS, the density of N a or N d , illumination intensity (P), the form of ohmic and rectifier metal contacts, and sample temperature. [10][11][12][13][14] Interface states, located between interlayers and semiconductors, act as recombination centers that can capture and release an electronic charge under illumination and temperature effect.…”

“…This confirms the photoconductive behavior of the diode. Upon illumination of the diode, a photocurrent is created by the photo-generated charge carriers at the interface on the diode [34][35][36][37][38][39]. The value of ideality factor and barrier height determined from the forward bias I-V characteristics for dark and 100 mW/cm 2 is given in Table 1.…”

“…Ters ve doğru beslem akımlarındaki davranışlar incelendiğinde imal edilen diyotun fotodiyot özelliği sergilediğini belirtmişlerdir. Aydınlatmadan sonra idealite faktöründeki artışı MY arayüzündeki homojensizliğe atfetmişler ve arayüzey durumlarının enerji dağılımının artan aydınlatma seviyesi ile arttığı ve seri dirence bağlı olarak değiştiği gözlemlenmiştir [39]. MPY ve MFY/MFYY yapıların elektriksel özellikleri metal yarıiletken arasındaki arayüzeysel özelliklere, yalıtkan/polimer arayüzey tabaka oluşumuna, Schottky engel yüksekliğindeki homojensizliğe ve seri dirence de bağlı olduğundan MYY yapılar ile benzerlik göstermektedir [4].…”
