Abstract: 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.

Abstract: 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.

Abstract: In an example, the present invention provides a method of manufacturing a solar module. The method includes providing a substrate member having a surface region, the surface region comprising a spatial region, a first end strip comprising a first edge region and a first interior region, the first interior region comprising a first bus bar, a plurality of strips, a second end strip comprising a second edge region and a second interior region, the second edge region comprising a second bus bar, the first end strip, the plurality of strips, and the second end strip arranged in parallel to each other and occupying the spatial region such that the first end strip, the second end strip, and the plurality of strips consists of a total number of five (5) strips. The method includes separating each of the plurality of strips, arranging the plurality of strips in a string configuration, and using the string in the solar module.

Abstract: A solar cell is provided including a substrate having a front and back side, a metallization pattern deposited on the front side, the metallization pattern including a plurality of front side bus bars each including fingers extending therefrom, and a plurality of back side bus bars deposited on the back side. On the front side, one front side bus bar is formed along an edge of the front side of the substrate, and a remainder of the front side bus bars are unequally spaced across the substrate. On the back side of the substrate, only one back side bus bar is formed along an edge of the back side of the substrate, and a remainder of the back side bus bars are unequally spaced across the substrate.
