Light active sheet and methods for making the same

摘要

A method for making a sheet of light active material. A first substrate is provided having a transparent first conductive layer. A pattern of light active semiconductor elements are formed. The pattern of light active semiconductor elements may be formed using an electrostatic attraction and transferring process. The light active semiconductor elements have an n-side and a p-side. Each light active semiconductor element has either of the n-side or the p-side in electrical communication with the transparent conductive layer. A second substrate having a second conductive layer is provided. The second substrate is secured to the first substrate so that the other of said n-side or said p-side of each said light active semiconductor element in electrical communication with the second conductive layer. Thus, a solid-state sheet of light active material is formed.
