Patent ID: 8809877

Claim:
A semiconductor voltage transformation structure, comprising: a first electrode layer; an electricity-to-light conversion layer formed on the first electrode layer; a second electrode layer formed on the electricity-to-light conversion layer; a first isolation layer formed on the second electrode layer; a third electrode layer formed on the first isolation layer; a light-to-electricity conversion layer formed on the third electrode layer; and a fourth electrode layer formed on the light-to-electricity conversion layer, wherein the first isolation layer, the second electrode layer and the third electrode layer are transparent to a working light emitted by the electricity-to-light conversion layer; the first electrode layer, the electricity-to-light conversion layer and the second electrode layer form a semiconductor electricity-to-light conversion structure; the third electrode layer, the light-to-electricity conversion layer and the fourth electrode layer form a semiconductor light-to-electricity conversion structure; and a bandgap energy of each of the second electrode layer, the first isolation layer, the third electrode layer is greater than a photon energy of the working light emitted from the electricity-to-light conversion layer.
