Organic photodetectors

Fig. 16.9. A white capital letter T" prepared by a laser printer (a) was placed on the 250-dpi organic photodetector matrix without organic transistors. The photocurrent of each detector is measured under light (80 mW cm 2). The...

Many variations of the basic OLED device structure have been investigated. The basic OLED structure can also be used for organic photodetectors and photovoltaic cells. 

Fig. 4.18. (a) Schematic of PDMS microchip used for on-chip chemiluminescence assay. Reagents are loaded into inlets 1 and 2 and are hydrodynamically pumped towards outlet three. Light is generated when the two reagents mix. For detection a P3HT PCBM photodetector is placed underneath the detection chamber of the microchip, (b) Responsivity of the organic photodetector and emission spectra of the chemiluminescence dyes (Prom [21] - Reproduced by permission of The Royal Society of Chemistry)...

This kind of filter can be fully integrated with the polymeric substrate of the microfluidic element, allowing a Lab-on-a-Chip suitable for low-cost disposable point-of-care diagnosis. This idea leads to integrated monolithic optical filters that can be attached to the substrate of the microfluidic chip or even to the photodetectors, when organic photodetectors are used. For example, a structured dye-doped polydimethylsiloxane (PDMS) layer can serve concurrently as a microfiuidic network and optical filter.
