Paper Abstract

User-controlled photochromic devices are currently under investigation due to their unique ability to harness solar energy for coloration while retaining user control over the depth of coloration. Such devices utilize both a chromogenic electrode and a photosensitive layer. One highly active photosensitive layer of interest for this application is titania, and this paper focuses on a highly porous titania film with low scattering loss and good uniformity that is deposited from a stable colloidal suspension. The stability of the suspension along with the low temperature heat treatment and ease of coating by dip-coating provide an attractive method for the deposition of these films. The performance of a user-controlled photochromic device containing such films is described.
