ABSTRACT:
An integrated array of solar cells, each cell having a positive and a negative electrode, is disclosed. A first grid comprising a plurality of non-intersecting electrically conductive members is affixed to an insulating substrate. Each single individual member of this grid forms the negative electrode of an individual cell of the array. Overlying and affixed to the negative electrodes and the surface of the substrate between these electrodes is a semiconductor layer of a first conductivity type. Isolated (i.e., non-touching or non-abutting) semiconductor regions of a second conductivity type form a plurality of PN junctions with the semiconductor layer. These P-N junctions are the active areas of the individual cells of the array. Each of the isolated semiconductor regions of the second conductivity type is solely coupled to an individual member of another grid whose members form the positive electrodes of the individual cells. Electrical interconnection is made through a non-active region of the semiconductor layer to couple the cells comprising the array in series circuit relationship.
