Abstract :
The possibilities of producing monograin powders of different A2B6 and chalcopyrite materials; different technologies of manufacturing monograin layers and cleaning of open surfaces of grains in the monograin layer by mechanical, chemical and electrochemical methods were studied. It was shown that up to now too low efficiency of solar cells by the monograin layer is associated with the insufficient cleaning of surfaces of crystals in the monograin layer before depositing the active contacts
