Abstract
A solar cell includes a first substrate having a first surface and a second surface. An underlayer is located over the second surface. A first conductive layer is located over the underlayer. An overlayer is located over the first conductive layer. A semiconductor layer is located over the conductive oxide layer. A second conductive layer is located over the semiconductor layer. The first conductive layer includes a conductive oxide and at least one dopant selected from the group consisting of tungsten, molybdenum, niobium, and/or fluorine.
Claims24
A method of making a coated article, the method comprising the steps of:
- supplying a glass substrate having a first surface and a second surface;
- applying a first coating over the first surface of the glass substrate;
- forming a second coating over the second surface of the glass substrate, wherein the second coating is formed by:
- applying an underlayer over the second surface of the glass substrate;
- forming a first conductive oxide layer over the underlayer by a chemical vapor deposition process, the method of forming the first conductive layer comprising either one of the following method steps:
- (a1) applying a first metal precursor material comprising a metal to form a first film;
- and
- (a2) applying a second metal precursor material comprising a metal to form a second film, wherein the second film is formed over the first film and the first film and second film together form the first conductive layer, or
