Abstract
A solar cell includes negative metal contact fingers and positive metal contact fingers. The negative metal contact fingers are interdigitated with the positive metal contact fingers. The metal contact fingers, both positive and negative, have a radial design where they radially extend to surround at least 25% of a perimeter of a corresponding contact pad. The metal contact fingers have bend points, which collectively form a radial pattern with a center point within the contact pad. Exactly two metal contact pads merge into a single leading metal contact pad that is wider than either of the exactly two metal contact pads.
