ABSTRACT:
A solar cell which has high efficiency and which can be fabricated at low cost is described. The cell includes a semiconductor wafer with a front radiation-receiving surface which is entirely open and free of current conducting grids and also includes an array of interconnection paths which carry photocurrent from the front surface through the cell to metal electrodes on the rear surface of the cell.
