Solution processable photodetectors operating up to 3 μm cut‐off wavelength based on HgTe nanocrystals are demonstrated. Ink‐jet printing is employed for the accurate deposition of the nanocrystals on the electrodes. The highly reproducible photodetectors exhibit high sensitivities for small illumination powers, making the devices ideal candidates for night vision applications.
