<p>A solar cell is mfd. by producing in a semiconductor substrate a pn-junction by ion implantation. On the substrate side which is exposed to the optical radiation, one or several areas are doped more intensively than other, followed by applying a metal contact to a small part of these areas. Masks are used to give these areas fishbone, comb, grate or star shapes. This cell gives a higher current yield and minimises the loss of active area due to contacting. Such a cell can be produced in mass prodn. at a reasonably low cost.</p> |
