Improvements in the efficiency of high-resistivity silicon concentrator solar cells with conventional top and rear contacts are reported. These improvements have been obtained despite a substantially sublinear increase in cell short-circuit current with increasing solar concentration. The theory of operation of cells of this type under short circuit is outlined. This theory accurately describes the observed current sublinearity and indicates how it can be eliminated.
