METAL ADHESION

A solar cell has a metal contact formed to electrically contact a surface of semiconductor material forming a photo-voltaic junction. The solar cell includes a surface region or regions of heavily doped material and the contact comprises a contact metallisation formed over the heavily doped regions...

Beschreibung
Zusammenfassung:	A solar cell has a metal contact formed to electrically contact a surface of semiconductor material forming a photo-voltaic junction. The solar cell includes a surface region or regions of heavily doped material and the contact comprises a contact metallisation formed over the heavily doped regions to make contact thereto. Surface keying features are located in the semiconductor material into which the metallisation extends to assist in attachment of the metallisation to the semiconductor material.
