Method and apparatus of fabricating an interconnector assembly

Method of making an interconnector assembly (11) for electrically interconnecting solar cells (21), wherein the method comprises:

• feeding a plurality of electrical conductors (2) that form an conductor array (17) defining interspaces (18) that are free from conductors (2), and
• applying at least one sheet (6, 7), preferably made of electrically insulating material, to a side of the conductor array (17), wherein the sheet (6, 7) has at least one contact zone (8) coming into contact with the conductors (2) and intermediate portions (9) overlapping with the interspaces (18) of the conductor array (17),
• characterized in that the step of applying the at least one sheet (6, 7) to a side of the conductor array (17) comprises:
• before the conductors (2) come into in contact with the sheet (6, 7) and/or when the conductors (2) are in contact with the sheet (6, 7):
• increasing the temperature in the at least one contact zone (8) of the sheet (6, 7) to a first temperature, wherein the first temperature is above the temperature at which the material forming that contact zone (8) becomes sticky, such that the conductors (2) are bonded to the sheet (6, 7) by the material of the contact zone,
• wherein the side (6a, 7a) of the sheet (6, 7) that faces away from the conductor array (17) is kept at a second temperature, wherein the second temperature is below the temperature at which the material forming the side (6a, 7a) of the sheet (6, 7) that faces away from the conductor array (17) becomes sticky,
• and/or wherein the intermediate portions (9) of the sheet (6, 7) at least partially are kept at a second temperature, wherein the second temperature is below the temperature at which the material forming the intermediate portions (9) becomes sticky.
