This research focuses on the UV‐Vis. absorbance spectra of the hybrid organic/inorganic complementary electro‐chromic device (ECD), comprising polyaniline‐poly(styrenesulfonic acid)[PANI‐PSSA] complexes and tungsten oxide (WO 3 ) thin film coupled in combination with a polymer electrolyte poly(2‐acrylamido‐2‐methyl‐propane‐sulphonic acid)[PAMPSA]. PANI‐PSSA microstructure surface images have been studied by AFM. By applying a potential of ˜3.0 V across the two external ITO contacts, we are able to modulate the light absorption also in the UV‐Vis region (200–900 nm) wavelength region. For example, the absorption changes from 1.20 to 0.6 at 720 nm.
