Abstract

Two-dimensional arrays of polarized energy-generating or energy-storing elements (20A, 20B, . . . , 20D; 21A, . . . , 21D; 22A, . . . , 22D; 23A, . . . , 23D; 24A, . . . , 24D; 25A, . . . , 25D), such as solar cells, batteries, thermoelectric generators or capacitors are formed as a matrix of rows and columns of elements, with the elements of each column being connected in series and the junctions between the series-connected elements in each column within the matrix being connected, in sequence, first to the corresponding junction in one of the adjacent columns and then to the corresponding junction in the other one of the adjacent columns. By connecting the junctions (32, 33) of alternate pairs of elements in the left hand column of the matrix to the respective junctions (32A, 33A) in the right hand column of a matrix having an even number of columns, the mathematical equivalent of a tubular matrix of elements is formed. When the invention is applied to arrays of solar cells, the problems due to shadowing the array are diminished.

Claims

(a) the positive pole of each element in each column is connected to the negative pole of the next adjacent element in the column;

(b) the positive pole of each second element in a column is connected to the positive pole of the corresponding element of one of the two adjacent columns; and

(c) the positive pole of each alternate second element in a column is connected to the positive pole of the corresponding element in the other of the two adjacent columns.

2. An array as defined in claim 1, further characterised in that the positive poles of the elements at the positive end of each column are connected to a common positive terminal, and the negative poles of the elements at the negative end of each column are connected to a common negative terminal.

3. An array as defined in claim 2 in which each element is a solar cell.

4. An array as defined in claim 3 in which each solar cell is a bifacial solar cell.

7. An array as defined in claim 2 in which each element is a capacitor.

8. An array as defined in claim 1 further characterised in that there are an even number of columns in the array and the junctions between the alternate pairs of elements in the leftmost column of the matrix are connected, respectively, to the junctions between the alternate pairs of elements in the rightmost column of the matrix.
