In this study,
Silver/n-type
Silicon/poly[N-9′-heptadecanyl-2,7–carbazole–alt-5,5-(4′,7′-di–2–thienyl-2′,1′,3′-benzothiadiazole:[6,6]-phenyl-C61-butyric
acid methyl ester/Gold (Ag /n-Si/ PCDTBT: PCBM/Au) organic metal-polymer
semiconductor Schottky barrier diodes were produced using 20% ​​PCDTBT and 80%
PCBM mixture as polymer interface. The current-voltage measurements of the
produced diodes in the 240 - 350 K temperature range and the diode ideality
factor values ​​at these temperatures were observed to vary non-linearly,
depending on the temperature in the range of 1.80 and 2.26. In the second phase
of the study, Indium Tin Okside/PCDTBT:PCBM/Silver (ITO/PCDTBT:PCBM/Ag) organic
solar cells were produced with 20%: 80% PCDTBT: PCBM volumetric ratio, and the
characteristics of the produced solar cell was investigated. As a result of the
investigation, it was observed that the power conversion efficiency of the
produced solar cell was found to be 0.85%.
