제목 Narrowband Blue-Selective Polymer Photodiodes
초록 we synthesized a conjugated polymer to realize narrowband blue-selective polymer photodiode. It was found that polymer exhibited a blue-selective absorption with a narrow full width and a wide optical band gap. We constructed a planar heterojunction structure as a blue-selective electron donor and non-absorbing acceptor, respectively; To enhance the photodiode performance, a minor amount of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) was introduced on the donor layer. By introducing the PCBM on polymer layer, external quantum efficiency was increased PCBM-doped device, while the dark current values maintained nearly constant. This external quantum efficiency boost leads to high detectivity. The physics behind the improved performance were fully discussed based on percolation pathway theory and space-charge-limited current analyses.
