Abstract
A solar cell has an active structure including a paint voltage source having a first paint layer structure comprising p-type pigment particles dispersed in a first-layer binder, and a second paint layer structure comprising n-type pigment particles dispersed in a second-layer binder. The second paint layer structure is in electrical contact with the first paint layer structure. The active structure further includes an electrically conductive contact structure having a first electrically conductive contact to the first paint layer structure, and a second electrically conductive contact to the second paint layer structure. At least one of the first electrically conductive contact and the second electrically conductive contact permits light to pass therethrough to the paint voltage source. A capacitive paint layer may be included to store electrical charge produced by the active structure. The active structure may be affixed to a support.
