Solar cell and assembly of a plurality of solar cells

A solar cell (1), comprising:

• a front side (10) and a rear side (20), wherein the solar cell is configured such that when the front side (10) is turned towards incident light charge carriers accumulate on the front side (10) and charge carriers of an opposite type accumulate on the rear side (20),
• in which the front side (10) is provided with a first pattern (13) of conductive elements (51, 52) which are connected to first contact points (15) on the rear side (20) by vias (14) in the solar cell,
• in which the rear side (20) is provided with a second pattern of conductive elements (22) which are connected to second contact points (21) on the rear side (20),
• wherein the first and second contact points (15, 21) are situated along a number of lines (30), in which the lines (30) extend substantially in a first direction along the surface of the rear side (20),
• wherein a line (30) from the number of lines (30) is an imaginary line providing a reference for determining a relative arrangement of the first and second contact points (15, 21),
• wherein the first contact points (15) are linearly situated on a first side of the lines (30) and the second contact points (21) are linearly situated on a second side of the lines (30),
• wherein the first pattern (13) of conductive elements is divided into a plurality of unit cells (18) arranged in a matrix structure, with each unit cell (18) including a subpattern of conductive elements (51, 52) and a via (14),
• wherein each subpattern is connected to a first contact point (15) on the rear side (20) by the via (14) in the unit cell, and
• wherein the unit cells of the matrix structure are arranged into a plurality of rows of unit cells (18) which extend in the first direction, with a first row of unit cells (18′) having a first width B1 along a first edge of the solar cell in a direction substantially perpendicular to the first direction, and a second row of unit cells (18″) having a second width B2 along a second edge of the solar cell, with B1<B2.
