Assembly of photo-voltaic cells

A method of manufacturing an assembly of photo-voltaic cells, the method comprising

• providing an electrical connection structure that provides for a series connection of the photo-voltaic cells,
• providing bypass diodes on said electrical connection structure, each bypass diode for connection in parallel with the photo-voltaic cells of a respective part of the series connection;
• arranging the photo-voltaic cells in a matrix with rows and columns of photo-voltaic cells;
• establishing electrical contact between contacts of the photovoltaic cells and the electrical connection structure, wherein the electrical connection structure comprises
• rows of first sub-matrix connection patterns, each first sub-matrix connection pattern providing one of the respective parts of the series connection, extending over a plurality of rows of photo-voltaic cells of the matrix, running back and forth along successive columns through the plurality of rows;
• second sub-matrix connection patterns, connecting the first sub-matrix connection patterns at ends of a pair of the rows of first sub-matrix connection patterns, each second sub-matrix connection pattern providing a further one of the respective parts of the series connection, extending over a plurality of columns of photo-voltaic cells of the matrix, running back and forth along successive rows through the plurality of columns.
