Title
(EN) OPTOELECTRONIC DEVICE AND METHOD OF MAKING THE SAME
Abstract
(EN)
An optoelectronic device (10) includes a first substrate (12) having a first surface (14) and a second surface (16); an underlayer (18) located over the second surface (16); a first conductive layer (20) over the underlayer (18); an overlayer (22) over the first conductive layer (20); a semiconductor layer (24) over the first conductive layer (20); and a second conductive layer (26) over the semiconductor layer (24). The first conductive layer (20) includes a conductive oxide and at least one dopant selected from the group consisting of tungsten molybdenum niobium and fluorine; and/or the overlayer (22) includes a buffer layer (42) including tin oxide and at least one material selected from the group consisting of zinc indium gallium and magnesium.
