Photovoltaic devices and methods of making

A photovoltaic device comprising:

• a plurality of electrically connected photovoltaic cells, wherein the photovoltaic cells of the plurality of photovoltaic cells comprise a conducting layer having a first surface and a second surface, the first surface facing an absorber layer;
• an insulating material disposed on the second surface over one of the photovoltaic cells;
• a conductive member on the insulating material, wherein the insulating material is configured to electrically insulate the conductive member from the second surface;
• a bus member electrically coupled to the one of the plurality of photovoltaic cells and to the conductive member;
• and
• an edge seal comprising a sealant material extending over at least a portion of the one of the plurality of photovoltaic cells;
• wherein the bus member is disposed between the edge seal and the plurality of photovoltaic cells, and wherein the bus member overlaps the conductive member to define a T-joint, the T-joint is disposed between the edge seal and the plurality of photovoltaic cells, and at least a portion of the bus member is not between the edge seal and the plurality of photovoltaic cells.
