Abstract

A transparent conductive layer includes a substrate, a first conductive layer disposed on the substrate, and a second conductive layer disposed on the first conductive layer, wherein the second conductive layer comprises a textured surface and an opening which exposes the first conductive layer, wherein the opening comprises a diameter of about 1 micrometer to about 3 micrometers. Also disclosed is a method of manufacturing the transparent conductive layer and a photoelectric device.
