Solar cell grid patterns

A solar cell having an electrode grid pattern on its light receiving surface comprising:

• a plurality of conductors arranged in a symmetrical pattern;
• one part of the pattern comprising, relative to a line extending toward the center region of the cell from an edge of the cell, a plurality of parallel conductors spaced from one another, each conductor subtending an angle which is bisected by the line at the crossing of that conductor with the line, each conductor terminating at both its ends at the peripheral edge portion of the cell, each conductor comprising a first portion on one side of the line which is a mirror image of a second portion on the other side of the line, each conductor thus being symmetrical relative to said line, said one part of the pattern occupying a 90.degree. quadrant which is bisected by the line,
• a second part of the pattern comprising a mirror image of the first part of the pattern;
• third and fourth parts of the pattern comprising a mirror image of said first and second parts of the pattern, respectively, and
• a common bus extending along said peripheral edge portion of the cell and in conductive contact with all of said conductors at their respective opposite ends,
• the spacing between different pairs of said parallel conductors being different, the spacing between those conductors closest to the peripheral edge being the greatest.
