Abstract
A thin film photovoltaic devices is described, having a glass substrate over which is formed a thin film silicon device having an n layer a p layer and a dielectric layer (typically silicon oxide or silicon nitride). To create a connection through the p layer to the underlying n layer a column of semi-conductor material is heated, the column passing through the various doped layers and the material in the column being heated or melted to allow migration of dopant between layer of the device in the region of the column.
