NOVELTY - Interconnecting a first solar cell adjacent to a second solar cell in an array of solar cells, comprises: providing a first solar cell adjacent to a second solar cell; etching a portion of the semiconductor layer of the first solar cell to expose a portion of a top surface of the backmetal layer of the first solar cell; and interconnecting the first solar cell and the second solar cell by coupling the exposed top surface of the backmetal layer of the first solar cell to a top surface of the second solar cell using an interconnect tab.    USE - The methods are useful for interconnecting a first solar cell adjacent to a second solar cell in an array of solar cells; and for forming an array of solar cells (all claimed).    ADVANTAGE - The method can efficiently facilitate assembling high-volume adjacent solar cells into a solar cell array.    DETAILED DESCRIPTION - Interconnecting a first solar cell adjacent to a second solar cell in an array of solar cells, comprises: providing a first solar cell adjacent to a second solar cell, where at least the first solar cell includes a semiconductor layer formed on top of a backmetal layer; etching a portion of the semiconductor layer of the first solar cell to expose a portion of a top surface of the backmetal layer of the first solar cell; and interconnecting the first solar cell and the second solar cell by coupling the exposed top surface of the backmetal layer of the first solar cell to a top surface of the second solar cell using an interconnect tab. INDEPENDENT CLAIMS are:    (1) a solar cell array comprising: a first solar cell formed of a semiconductor layer provided on top of a backmetal layer, where a portion of the semiconductor layer of the first solar cell is etched to expose a portion of a top surface of the backmetal layer of the first solar cell; and a second solar cell provided adjacent to the first solar cell, where the first solar cell and the second solar cell are interconnected using an interconnect tab by coupling the etched portion of the top surface of the backmetal layer of the first solar cell to a top surface of the second solar cell; and    (2) a method for forming an array of solar cells, comprising: providing a set of solar cells, where a solar cell includes a semiconductor layer formed on top of a backmetal layer leaving a portion of a top surface of the backmetal layer exposed; applying an adhesive to a film layer; placing the set of solar cells onto the film layer; interconnecting the set of solar cells using one or more interconnect tabs by coupling the exposed top surface of the backmetal layer of a first solar cell to a top surface of an adjacent second solar cell; applying adhesive on the set of interconnected solar cells; and laminating a top film to the set of interconnected solar cells to form an array of solar cells.
