Patent ID: 8012317

Claim:
A method of making an electrode structure for a photovoltaic device, the method comprising: providing a glass substrate; etching and/or patterning at least one major surface of the glass substrate so as to form a textured surface of the glass substrate; sputter-depositing a substantially conformal front electrode on the textured surface of the glass substrate, the front electrode being substantially conformal so that both major surfaces of the front electrode are textured in a manner similar to the textured surface of the glass substrate, and wherein the substantially conformal front electrode formed on the textured surface of the glass substrate is adapted to be provided at a light incident side of a photovoltaic device; and determining a quantum efficiency (QE) curve for a photovoltaic device, and forming the front electrode in a manner so that a maximum transmission area of the front electrode is located under a peak area of a combination of the QE curve and a light source spectrum to be used to power the photovoltaic device.
