Abstract
A solar cell can include a conductive foil having a first portion with a first yield strength coupled to a semiconductor region of the solar cell. The solar cell can be interconnected with another solar cell via an interconnect structure that includes a second portion of the conductive foil, with the interconnect structure having a second yield strength greater than the first yield strength.
Claims11
A photovoltaic (“PV”) module, comprising:
- a first solar cell that includes a first conductive foil, wherein the first conductive foil is a single layer of material having a first portion with a first yield strength and a second portion with a second yield strength, wherein the first portion is disposed above and coupled to a semiconductor region of the first solar cell and wherein the second portion extends past an edge of the first solar cell;
- and
- an interconnect structure coupled to a second solar cell, wherein the interconnect structure includes the second portion;
- wherein the second yield strength is different than the first yield strength.
