Abstract:
The present thesis can be divided into three areas:1) the
fabrication of a low temperature photo-luminescence and photoconductivity
measuring unit 2) photo-luminescence in the chalcopyrite
CulnSez and CulnS2 system for defect and composition analysis and
3) photo-luminescence and photo-conductivity of In:JS3. This thesis
shows that photo-luminescence is one of most essential semiconductor
characterization tool for a scientific group working on photovoltaics.
Tools which can be robust, non-destructive, requiring minimal sample
preparation for analysis and most informative of the device
applications are sought after by industries and this thesis is towards
establishing photo-luminescence as "THE" tool for semiconductor
characterization. The possible application of photo-luminescence as a
tool for compositional and quality analysis of semiconductor thin
films has been worked upon by this thesis. Photo-conductivity
complement photo-luminescence and together they provide all the
information required for the fabrication of an opto-electronic device.
