Abstract
Variable bandgap conjugated donor–acceptor small molecule thin films show absorption spectra similar to those of human eye's photoreceptors. Photoactive devices interfaced with a bio-electrolyte reveal capacitive photocurrent response making them suitable for future full-colour retinal prosthesis.
