This engineering study reports optical and electrical characteristics of photonic gel cells made from a PS-b-P2VP lamellar film and a hydrogel electrolyte on ITO glass. Applying 2 V between two facing electrodes over 30 minutes shifted the device reflectance peak from 538 nm up to 604 nm with limited bandwidth…
