Patent ID: 8796534

Claim:
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 B 1 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 B 2 along a second edge of the solar cell, with B 1 <B 2 .
