Abstract

Solar devices and methods for producing solar devices are disclosed. In some examples, a solar device includes solar cells arranged in a shingled manner such that adjacent long edges of adjacent ones of the solar cells overlap. The adjacent long edges have a non-linear shape that has protruding portions. The solar device includes contact pads arranged in the protruding portions of the adjacent long edges such that the contact pads of the adjacent ones of the solar cells are electrically connected.
