Abstract
A multi-junction photovoltaic device comprises a first sub-cell and a second sub-cell, the second sub-cell overlying the first sub-cell such that incident light passes through the second sub-cell before the first sub-cell. The light-receiving surface of the second sub-cell comprises a layer of a transparent conductive material and one or more metal tracks extending in a first direction and in contact with the layer of transparent conductive material. A layer of electrically insulating material is provided on the light receiving surface of the second sub-cell located under one end of the one or more metal tracks at an edge of the device, and an electrically conductive pad is provided over the layer of electrical insulator and in electrical contact with the one or more metal tracks to provide electrical contact to an external circuit.
