ZnO oxide is a promising material for optoelectronics because of its wide and direct gap (Eg=3.4 eV). Pure and doped zinc oxide powders of various grain sizes have been synthesized by vaporisation-condensation method using a solar furnace. The initia

Pure and doped zinc oxide powders of various grain sizes have been synthesized by sublimation-condensation technique using a solar furnace. The initial powders contained from 0 to 5% mol of In2O3. X-ray diffraction technique (XRD) has been used to me

The effects of source material grain size distribution on film structure and morphology were investigated in the growth of Cu(In,Ga)Se 2 thin films by close-spaced vapor transport. These films are designed to be used as absorbers in solar cells. The
