1. A solar cell module comprising:
a plurality of III-V compound semiconductor multijunction solar cells, each solar cell of the plurality of solar cells comprising a front surface, a rear surface, a first metal contact in correspondence with the rear surface and forming a contact of a first polarity type to the solar cell, and a metallic bonding pad on the front surface of the solar cell forming a contact of a second plurality type to the solar cell;
a planar support;
a conductive layer disposed on an upper surface of the planar support, the conductive layer comprising a first conductive section and a second conductive section, each section being electrically isolated from each other by at least one groove traversing the conductive layer, wherein the second conductive section comprises a plurality of substantially elongated sub-portions at least some of which extend between sub-portions of the first conductive section, wherein each of the solar cells is disposed over the first conductive section but not over the second conductive section;
each first metal contact of each solar cell of the plurality of the solar cells being conductively bonded to the first conductive section such that the first metal contact of each solar cell of the plurality of solar cells is electrically connected to the first conductive section; and
a plurality of discrete electrical interconnects, each discrete electrical interconnect coupling the metallic bonding pad on a respective solar cell to a respective portion of the second conductive section of the conductive layer.
