In an example, a method includes providing a photovoltaic string comprising a plurality of from 2 to 45 strips, each of the plurality of strips being configured in a series arrangement with each other, each of the plurality of strips being coupled to another one of the plurality of strips using an electrically conductive adhesive (ECA) material, detecting at least one defective strip in the photovoltaic string, applying thermal energy to the ECA material to release the ECA material from a pair of photovoltaic strips to remove the defective photovoltaic strip, removing any residual ECA material from one or more good photovoltaic strip, aligning the photovoltaic string without the damaged photovoltaic strip, and a replacement photovoltaic strip that replaces the defective photovoltaic strip, and curing a reapplied ECA material on the replacement photovoltaic strip to provide the photovoltaic string with the replacement photovoltaic strip.

In an example, the present invention provides a method of separating a photovoltaic strip from a solar cell. The method includes providing a solar cell, placing the front side of the solar cell on a platen such that the backside is facing a laser source, initiating a laser source to output a laser beam having a wavelength from 200 to 600 nanometers and a spot size of 18 to 30 microns, subjecting a portion of the backside to the laser beam at a power level ranging from about 20 Watts to about 35 Watts to cause an ablation to form a scribe region having a depth, width, and a length, the depth being from 40% to 60% of a thickness of the solar cell, the width being between 16 and 35 microns to create a plurality of scribe regions spatially disposed on the backside of the solar cell.
