Abstract

A cell with its absorption band in the visible spectrum, comprising a p- or n- doped substrate contg., on the window side, a grid of the opposite type, i.e. n- or p-, and covered with a transparent dielectric. The transparent dielectric is charged to a small part of its total height by trapped ions which are positive or negative when the substrate is p- or n- type respectively, the ion-density being sufficient to cause an inversion at the substrate surface. The pref. substrate is Si, which, if p-type, is covered with SiO2 doped with e.g. Mg++, Ca++, Zn++; if the Si is n-type, the SiO2 is doped with Br-, Cl-, OH- or I-. The advantage, esp. for space-vehicles, is the min. efficiency of 17%, as compared with the low efficiency of 7-11% obtd. from known cells.
