Organic Photodetector
Multiple Photodectors in Stacked ArchitectureA new architecture for organic photodetectors uses multiple layers to provide a tunable response specific to the wavelength of interest. The single-device design, which uses multiple organic photodetector subcells in a stacked/tandem architecture, uses organic semiconductors with complementary optical absorption for broadband optical response. The device permits a tunable spectral response in various spectrums, and the response from each individual active compound material can be separately tuned. The optical responsibility of the organic photodetector can be broadband, spanning the ultraviolet, visible, and near-infrared. The devices can be engineered with independent, user-specified responsivity in both visible and infrared. This lower cost, high throughput design is suitable for large area detectors, night vision, detectors for instrumentation, etc.MN-IP Try and BuyTryTrial period is up to 24 monthsTrial fee is $10,000 for 24 monthsTrial fee is waived for MN companies or if sponsoring $50,000+ research with the UniversityNo US patent expenses during trial periodBuy$25,000 conversion fee (TRY to BUY)Royalty rate of 3% (2% for MN company)Royalty free for first $1M in sales** View the Term Sheet **** Contact Kevin Nickels for specific details. **High Throughput Processing, Less Expensive, LightweightTraditional photodetectors, made from silicon or other inorganic semiconductors, can be expensive, difficult to make, and may suffer from stability issues (especially for large surface area applications). Because of their fabrication methods, these devices are limited to planar surfaces and are not compatible with high throughput processing. Organic photodetectors have been developed but are limited to a specific narrow wavelength and are not easily tunable to a specific application. This new, high-throughput design offers several advantages over current photodetector design (both traditional and organic). They have broad, highly tunable absorption spectra with large absorption coefficients, are compatible with large areas, are lightweight and can be deposited on curved surfaces.BENEFITS AND FEATURES:Broad, highly tunable absorption spectra with large absorption coefficientsCompatibility with large areasHigh throughput processingAbility to be deposited on curved surfacesLightweightAPPLICATIONS:MilitaryPhotoconductors and charge-coupled devicesReceivers for remote control devicesFlexible displaysNight vision equipmentCamera sensorsPhotoconductors, charge-coupled devices, and photomultiplier tubesEnhanced vision systems (EVS) in aircraftActive pixel sensors for camerasCryogenic particle detectorsInfra remote control for television sets, DVD players and home theater systemsOrganic photovoltaic cell (OPVC)Phase of Development - Proof of concept.
