Patent ID: 7439600

Claim:
A photovoltaic device comprising a plurality of photovoltaic cells of a p-i-n type placed on a first substrate, wherein said cells are positioned parallel to one another and wherein electrically conductive layers connect a p-type layer of each cell with an n-type layer of an adjacent cell on one side and connect the n-type layer of said same cell with the p-type layer of the adjacent cell on the other side, except for cells located at an outer border of the photovoltaic device, so as to electrically connect all the consecutive cells of the photovoltaic device in series, wherein at least the p-type layer and the n-type layer of a photovoltaic cell of the photovoltaic device are both located in the same layer on the first substrate, parallel to one another and on top of the electrically conductive layer, wherein said p-type layer and said n-type layer are of equal thickness.
