Completed TRL 3 (started at 2, targeting 3)
Solution-processed organic/inorganic materials show promise as sensing materials that are light-weight, inexpensive, and flexible while allowing simple fabrication techniques such as inkjet printing. The proposed research focuses on the development of solution-based materials and fabrications methods for infrared (IR) sensors applicable in a wide range of space missions, concentrating on crew health monitoring and remote sensing. We will develop a composite material system that enables efficient electrical carrier transfer and transport with a tailored IR spectral response. We will incorporate i) different quantum dots and structures for specific spectral sensitization and maximal light absorption; ii) enhance interparticle interaction through ligand engineering and surface passivation to improve inter-particle energy transfer; iii) extend IR sensitivity by investigating methods to improve nanocrystal stability (core-shell, ligands, and oxygen-free processing); and iv) combining broad-spectrum absorbing organic polymers to maximize charge transfer. These materials and device efforts are coupled with structural, chemical, optical (continuous wave and time-resolved) and electrical characterization. Novel device structures will be systematically evaluated to ascertain the nanostructures necessary to optimize detectivity, quantum efficiency for IR sensing and power conversion efficiency (PCE). This projects outcome will be a commercially comparable NIR detector, photocurrent >1.3 uA and max power > 324 nW, to function as a crew health monitoring platform, fabricable on demand in space using lightweight materials.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
