    Abstract: A method for manufacturing a solar ceil from a silicon semiconductor substrate of a first conductivity type, the substrate having a front and a rear surface; and creating on the rear surface a doped layer of the first conductivity type, as rear surface doped layer as back surface field in the solar cell; creating on the front surface a doped, layer of a second conductivity type as front surface doped layer as an emitter layer in the solar cell, the second conductivity type being opposite to the first conductivity type; wherein the method further includes: creating recesses in the rear surface to pattern the rear surface doped layer of the first conductivity type so as to create back surface field areas, the recesses being void of rear surface doped layer material, and creating via holes in the substrate, each via hole being positioned within an associated recess.

    Abstract: In an assembly of photo-voltaic cells, the cells are arranged in a matrix and connected in series. Bypass diodes are connected in parallel respective parts of the series connection. In each of these parts, the cells are arranged in a sub-matrix, for example of 4×4 cells. The matrix contains rows of sub-matrices that have identical first sub-matrix connection patterns, except at the edge of the matrix, where sub-matrices with a second sub-matrix connection pattern are used. Each first sub-matrix connection pattern extends over a plurality of rows of photo-voltaic cells of the matrix, running back and forth along successive columns through the plurality of rows. Each second sub-matrix connection patterns extends over a plurality of columns of photo-voltaic cells of the matrix, running back and forth along successive rows through the plurality of columns. The second sub-matrix connection patterns, connect first sub-matrix connection patterns at ends of pairs of the rows of first sub-matrix connection patterns.

    Abstract: Known photovoltaic cells with wrap through connections have output terminals of both polarities on its back surface, one of which is coupled to the front surface via the wrap through connections. The invented solar cell is manufactured by creating an emitter layer on the back surface. Electrode material is applied in mutually separate first and second areas on the back surface. The electrode material in the first area contacts the emitter. The second area covers a surrounding of a hole that provides for the connection on the back surface. The electrode material in the second area lies on the emitter and around the second area the emitter is interrupted by a trench. On the front surface a further area of electrode material is applied over the hole. If necessary the electrode material in the second area on the back surface is applied on a supporting surface that is substantially electrically isolated from current flowing laterally through the emitter layer underneath the first area.
