ABSTRACT:
A grid pattern for a solar cell of the type including a base layer of one conductivity type and an emitter layer of opposite conductivity type. The solar cell may have a square face and in this case the grid pattern is in the form of four symmetrical sub-patterns, each in a different quadrant of the square. Each such sub-pattern comprises a set of nested V shaped grid conductors, the apices of which lie on a common diagonal of the square and the ends of which connect to a common bus conductor at the peripheral edge of the square. Within each quadrant, the sub-pattern comprises a symmetrical pattern relative to a diagonal of the square. The pattern reduces the effect of line and sheet resistance and thereby permits more of the photon induced charge carriers to be collected and also permits a relatively large part of the cell face area to be available for the reception of photons.
