NOVELTY - Structure for fabricating a photovoltaic strip comprises: (a) a first grid pattern associated with a front surface of a photovoltaic cell; (b) a second grid pattern associated with a back surface of the photovoltaic cell; (c) an alignment characteristic that each grid line of the first grid pattern corresponds to a single row of blocks of the second grid pattern in the second direction; and (d) a misalignment characteristic that the first strip columns of the first grid pattern shifts away from any one of the second strip columns of the second grid pattern.    USE - The structure is useful for fabricating a photovoltaic strip (claimed), such as solar cells or panels.    ADVANTAGE - The structure provides an easy to use process that relies on conventional technology such as silicon materials in the photovoltaic strips. The method provides a process that is compatible with conventional process technology without substantial modifications to conventional equipment and processes. It provides an improved grid pattern with grid line density for increased current density and one finger-like conductive grid line on the front surface of solar concentrator module per concentrating element, which has less blocking or shadowing effect and high module efficiency.    DETAILED DESCRIPTION - Structure for fabricating a photovoltaic strip comprises: (a) a first grid pattern associated with a front surface of a photovoltaic cell, where the photovoltaic cell has a first dimension in a first direction and a second dimension in a second direction, the second direction is perpendicular to the first direction, the first grid pattern includes first strip columns in parallel with the first direction and grid lines in parallel with the second direction crossing the first strip columns, each of the first strip columns has a first width and a first length equal to the first dimension, the grid lines are equally spaced to cumulatively cover substantially the first length, each of the grid lines has a second width and a second length substantially equal to the second dimension, and the second width is substantially smaller than the second length; (b) a second grid pattern associated with a back surface of the photovoltaic cell, the second grid pattern including blocks separated by streets in parallel with the second direction and by second strip columns in parallel with the first direction, each of the blocks has a third width provided between two neighboring streets, each of the streets has a fourth width provided between two neighboring blocks, each of the second strip columns has a fifth width and a length equal to the first dimension, and the fourth width is smaller than the third width; (c) an alignment characteristic that each grid line of the first grid pattern corresponds to a single row of blocks of the second grid pattern in the second direction; and (d) a misalignment characteristic that the first strip columns of the first grid pattern shifts away from any one of the second strip columns of the second grid pattern. An INDEPENDENT CLAIM is included for a method of fabricating a photovoltaic strip for solar concentrator module.
