Team prints polymer photo diodes on hemispherical substrate
9/6/2018

University of Minnesota researchers report crafting energy-efficient polymer-based photo diodes, using a custom 3D printer, ink containing silver nanoparticles and a bowl-shaped glass substrate measuring about 20 millimeters in diameter. The researchers placed a spot of eutectic gallium-indium at each junction on the device as a top electrode.
