Abstract : INVESTIGATION ON THE FEASIBILITY OF STACKING PHOTOVOLTAIC LAYERS OF DIFFERENT II-VI semiconductin compounds in intimate electrical contact in order to convert a larger fraction of the sun's radiation into electrical power than is possible in a single layer. Five problems are described and the results are tabulated. These problems are: the production of ZnS, ZnSe, ZnTe, dSe, CdS, and CdTe crystals and/or thin films; CdS solar cell mechanism; the preparation of various configurations for a study of heterojunctions including ZnS-CdS, ZnTe-CdS, CdSe-CdS, dTe-CdS, ZnSe-CdSe; and theoretical examinations of the abrupt p-n junction and the effect of surface states upon the electrical properties of semi-conducting crystals.
