ABSTRACT:
Generally spherical shaped semiconductor particles comprising an inner core of one conductivity type and a thin peripheral layer of opposite conductivity type are produced in a fluidized bed reactor. Silicon particles introduced into the reactor are built up to a desired nominal diameter by vapor deposition from a silicon and dopant containing atmosphere introduced into the reactor; by changing the dopant constituent, the outer peripheral layer is then deposited. One use of such particles is in fabrication of a solar cell, wherein an array of the particles is located on an insulating sheet and overlying conductive layers, insulated from each other, make contact respectively with the peripheral layers and with areas of the core regions, exposed by etching. The particles also may be used to fabricate semiconductor devices, e.g., by use of orientation dependent etches to define flat surfaces on the particles parallel to specific crystallographic planes. Use of other semiconductor materials, e.g., germanium and cadmium slfide also is described.
