SOLAR ROOF TILE CONNECTORS

Abstract:

One embodiment can provide a photovoltaic roof tile. The photovoltaic roof tile can include a plurality of photovoltaic structures positioned between a front cover and a back cover, a bridge electrode coupled to a front-side busbar belonging to a photovoltaic structure, and a metallic strip positioned on a back side of the bridge electrode. The bridge electrode can include a substrate and at least one metallization layer positioned on a back surface of the substrate, and the metallization layer is electrically coupled to both the front-side busbar and the metallic strip, thereby enabling electrical coupling between the front-side busbar and the metallic strip.
