Patent ID: 8247682

Claim:
A cadmium telluride based thin film photovoltaic device, comprising: a substrate; a transparent conductive oxide layer on the substrate; a plurality of metal gridlines directly contacting the transparent conductive oxide layer, wherein the plurality of metal gridlines are oriented in a first direction; a cadmium sulfide layer on the transparent conductive oxide layer; and, a cadmium telluride layer on the cadmium sulfide layer; wherein a plurality of scribe lines are defined through the thickness of the cadmium sulfide layer and the cadmium telluride layer to define a plurality of photovoltaic cells such that the plurality of scribe lines are oriented in a second direction that intersects with the first direction, and wherein the plurality of scribe lines comprises a first isolation scribe isolating the transparent conductive oxide layer into individual photovoltaic cells, a series connecting scribe electrically connecting adjacent individual photovoltaic cells to each other in series, and a second isolation scribe to isolate a back contact into individual photovoltaic cells, the first isolation scribe traversing the transparent conductive oxide layer and the metal gridlines, the cadmium sulfide layer, and the cadmium telluride layer.
