Embodiment Construction
[0020] image 3 The contacting between solar cells 2 and contact elements 3 of a solar cell string according to the invention is shown. Except for the specially constructed contact elements described in detail below, the solar cell string is approximately the same as figure 1 The solar cell strings in are constructed of the same type. The rear solar cell 2 is electrically connected by means of such a contact element 3 . Contact elements 3 made of metal strips respectively connect one or more n-type doped (n-dotiert) regions (negative pole) and one or more p-type doped (p-dotiert) regions (positive pole) of the solar cell. ) are connected. Such as image 3 As shown, a known insulating strip 4 extending in the longitudinal direction x is arranged on the solar cell 2 in the region of the n-pole (cf. figure 2 ). The insulating tape consists essentially of a non-conductive or only weakly conductive material, for example a flexible plastic material. The insulating material c...
