Abstract: The regularities of recrystallisation of initial powders of cadmium and zinc chalcogenides and chalcopyrites in different molten fluxes are studied. It is shown that the capillary phenomena in the solid–liquid phase boundary, wetting of the solid phase with the liquid flux phase are the processes that determine the mechanism of recrystallisation. Results indicate to the possibility of manufacturing of powders of complicate semiconductor materials in monograin form and with qualities acceptable for Monograin Layer (MGL) design of solar cells. Influence of several technological processes to parameters of monograin powders and MGL solar cells are studied.

Keywords: metal powders; cadmium chalcogenides; zinc chalcogenides; cadmium chalcopyrites; solar cells; zinc chalcopyrites; molten fluxes; recrystallisation; mechanism; kinetics; monograin layers; MGL; solar cell structures; powder materials; semiconductor materials.
