Photopyroelectric (PPE) spectroscopy, in the 350–1,075 nm wavelength range, was used to study the optical properties of electropolymerized melanin films on indium tin oxide (ITO) coated glass. The PPE intensity signal as a function of the wavelength λ, Vn(λ) and its phase Fn(λ) were independently measured. Using the PPE signal intensity and the thermal and optical properties...
