A dye-sensitized solar cell module (1) has at least two dye-sensitized solar cell units (2a-c) arranged adjacent each other and connected in series. Each dye-sensitized solar cell module has a porous insulating substrate (7), a first porous conducting layer (4) formed on one side of the porous insulating substrate (7) and a second porous conducting layer (5) formed on an opposite side of the porous insulating substrate (7). A series connecting element (6) penetrates through the porous insulating substrate (7) and extends between the first porous conducting layer (4) of one of the cell units and the second porous conducting layer (5) of the adjacent cell unit. Each of the cell units is surrounded by an ion barrier (12) in the form of a non-porous layer penetrating through the porous insulating substrate (7) to prevent the electrolyte from leaking to an adjacent cell unit.

An optoelectronic device has a layered construction, comprising a base layer, a first conductive layer, a photoactive layer and a second conductive layer. Plural separation channels extending through the photoactive layer and the first conductive layer separate the photoactive layer into photoactive regions, and insulator material extends through the respective separation channels to the base layer. Between adjacent photoactive regions, electrical connectors extend inside the lateral extent of the insulator material between a surface of a second electrode that is in electrical contact with one photoactive region to an opposing surface of a first electrode that is in electrical contact with the other photoactive region. By forming the electrical connectors extend inside the lateral extent of the insulator material, the overall size of the connection is minimised.
