Abstract:
A solar cell comprising an active structure including:a voltage source having a p-type semiconductor layer structure and an n-type semiconductor layer structure in electrical contact with each other, at least one of the semiconductor layer structures being a paint layer structure comprising first-layer paint pigment particles dispersed in a first-layer binder, wherein the paint layer structure has a thickness of from about 0.0005 to about 0.0015 inch, and wherein the first-layer paint pigment particles are selected from the group consisting of p-type pigment particles and n-type pigment particles; and an electrically conductive contact structure having a first electrically conductive contact to a first one of the semiconductor layer structures, and a second electrically conductive contact to a second one of the semiconductor layer structures, at least one of the first electrically conductive contact and the second electrically conductive contact permitting light to pass therethrough to the voltage source.
