Title: Innovations of Sonali Das
Introduction
Sonali Das is an accomplished inventor based in Orlando, FL, known for her significant contributions to the field of photonics and solar energy. With two patents to her name, she has developed innovative technologies that enhance the efficiency of light trapping and neuromorphic computing.
Latest Patents
Her latest patents include an "Omnidirectional polarization independent all-dielectric light trapping scheme" and a "Photonic synapse based on graphene-perovskite quantum dot for neuromorphic computing." The first patent presents a leaf-inspired biomimetic light trapping scheme designed for ultrathin flexible graphene-silicon Schottky junction solar cells. This approach utilizes lossless silica and titania nanoparticles to mimic the essential light trapping mechanisms of a leaf, focusing on both waveguiding and scattering. Importantly, this scheme employs two optically tuned layers without requiring nano-structuring of the active silicon substrate, thus preventing optical gain loss due to recombination. The second patent describes a phototransistor device that functions as an artificial photonic synapse. This device includes a substrate with a graphene source-drain channel and a perovskite quantum dot layer made from methylammonium lead bromide. The operation method involves applying fixed voltages to the gate and across the graphene channel, with presynaptic signals applied as stimuli, allowing for the measurement of postsynaptic signals.
