Abstract

Disposable and miniaturized organic photodiodes with spectral-resolving capabilities are fabricated based on polymeric conductive films doped with cyanine dyes by a drop-on-demand (DoD) inkjet method. The sensitivity and spectral resolution of the photodiodes at the J-aggregate absorption peaks of the corresponding cyanine dyes are improved by at least 800 times after the sequential in situ stacking of inkjet printed functional layers and optimization of the architecture, including the layer thickness and J-aggregate formation. The photodiodes are integratable onto the flowcytometry chips with waveguide laser arrays, demonstrating a spectral-resolving capability of ∼0.1 nm.
