Characterization of mechanically synthesized AgInSe2 nanostructures

Popis výsledku v původním jazyce

A quantum dot (QD) solar cell is an emerging field in solar cell research that uses QDs as the photovoltaic material. QDs have band gaps that are tunable across a wide range of energy levels by changing the QD size. Embedding different sized dots withinthe absorbing layer encourages harnessing the maximum spectrum energy. Also, other effects like a very high surface to volume ratio and quantum transport make them attractive for future devices. AgInSe2 (AIS) nanoparticles with tetragonally distorted phase have been prepared by mechanically alloying the synthesized bulk AIS powder at room temperature in a planetary ball mill under Ar in an attempt to create QDs. Nanoparticles are formed of similar to 10 nm in size. These ball-milled nanoparticles contain different shapes and the Rietveld analysis of X-ray powder diffraction data reveals their detailed structural features. High resolution transmission electron microscope images also detect the presence of the tetragonal phase in ball-mil
