CELL ARRAY AND METHOD OF MAKING THE SAME

摘要

An array of a plurality of cells, e.g. solar cells, formed on a stack (10d) comprising an insulating substrate layer (12), whereon at least a first electrical contact layer (14), an intermediate layer (16), and a second electrical contact layer (18) are supported, is disclosed. The array comprises at least a first cell (22) and a second cell (24) adjacent to each other and being separated from each other by at least one insulating ridge (26) extending through the second contact layer (18), the intermediate layer (16) and the first contact layer (14) toward the substrate layer (12); wherein the first cell (22) comprises a conductive member (32) extending through the second layer (18) and the intermediate layer (16) toward the first contact layer (14), the conductive member (32) being insulated against the intermediate layer (16) and the second contact layer (18) of the first cell by surrounding insulating material; wherein the conductive member (32) comprises a conductive portion (34) extending from an end of the conductive member (32) remote from the substrate layer (12) for electrically connecting the first cell to the second cell; wherein the insulating ridge (26) has a certain length extending over the entire length of the first and second cells (22, 24), the conductive member having a certain longitudinal extension in a direction parallel to the insulating ridge (26), the longitudinal extension of the conductive member (32) being substantially shorter than the length of the insulating ridge (26).
