Abstract
Organic photodiode array has recently attracted a lot of attention for large-area light detection applications and imaging. In this work, Organic photodiode 3 × 2 (Sample A), 4 × 3 (Sample B), 5 × 4 (Sample C), and 6 × 5 (Sample D) arrays based on copper phthalocyanine (CuPc)/C60 planar heterojunction in which CuPc used as optical sensitive material were fabricated and characterized. It is found that the dark current density of the device increases as the array increases through experimental data. A circuit model was constructed to analyze the cause of this phenomenon, and an analytical expression between dark current density and array size was obtained.
