Title: Self-powered and reversible light-directed electrophoretic deposition device for use in smart windows and photodetector displays

Abstract

According to one embodiment, a system includes a first sheet being nonopaque, a second sheet being nonopaque spaced from the first sheet, a spacer positioned between the first sheet and the second sheet, a chamber defined between the first and second sheets and the spacer, and a fluidic solution in the chamber. In addition, the first sheet includes a photoconductive layer. Moreover, solution has a plurality of particles, where the particles in the solution are attracted to illuminated portions of the photoconductive layer upon illumination of said portions in the absence of an external voltage applied to the first and second sheets.
