ABSTRACT:
An inexpensive photovoltaic device made using particulate silicon is described. Silicon particles of a particular type having a size range of from 300 to 1000 micrometers are sintered to a metallic substrate to form an ohmic contact therebetween. The particles and the substrate are provided with an insulating layer except for the top surfaces of the silicon particles, to which a layer of the opposite type is applied to form p-n junctions in the particles. A second electrode is then applied either directly or, preferably, via a first application of a transparent conductive coating. The device is then, preferably, covered with a light transparent member to provide a hermetic seal.
