METHOD OF MAKING AN ARRAY OF INTERCONNECTED SOLAR CELLS

Method of making an array of interconnected solar cells, including a) providing a continuous layer stack (1) of a prescribed thickness on a substrate (8), the layer stack (1) including an upper (2) and a lower (3) conductive layer having a photoactive layer (4) and a semiconducting electron transpor...

Summary:Method of making an array of interconnected solar cells, including a) providing a continuous layer stack (1) of a prescribed thickness on a substrate (8), the layer stack (1) including an upper (2) and a lower (3) conductive layer having a photoactive layer (4) and a semiconducting electron transport layer (6) interposed there between; b) selectively removing the upper conductive layer (2) and the photoactive layer (4) for obtaining a contact hole (10) exposing the semiconducting electron transport layer (6); c) selectively heating the layer stack (1) to a first depth (dl) for obtaining a first heat affected zone (12) at a first centre-to-centre distance (sl) from the contact hole (10), the first heat affected zone (12) being transformed into a substantially insulating region with substantially the first depth (dl) in the layer stack, thereby locally providing an increased electrical resistivity to the layer stack (1).
