Abstract:
The study is undertaken with an objective to investigate the linkage between air-sea fluxes in the Indian Ocean and monsoon forcing. Since the monsoon activity is linked to fluxes, the variability of surface marine meteorological fields under the variable monsoon conditions is also studied. The very objective of the present study is to document various sea surface parameters of the Indian Ocean and to examine the anomalies found in them. Hence it is attempted to relate the anomaly to the variability of monsoon over India, highlighting the occasion of contrasting monsoon periods. The analysis of anomalies of surface meteorological fields such as SST, wind speed and direction, sea level pressure and cloud cover for contrasting monsoons are also studied. During good monsoon years, the pressure anomalies are negative indicating a fall in SLP during pre-monsoon and monsoon months. The interaction of the marine atmosphere with tropical Indian Ocean and its influence on ISMR continue to be an area of active research.

Abstract:
This thesis is devoted to the development of a relatively new, rapidly
developing quaternary semiconducting material (viz., Cu2ZnSnS4) used for
photovoltaic applications. This semiconductor, commonly known as CZTS, is
closely related to a family of materials that have been used for solar cell
applications. It is a compound semiconductor made of copper, zinc, tin and
sulfur, which are sufficiently abundant elements; none of them is harmful to the
environment even at large scale usage. Aim of this study is to fabricate CZTS
solar cells through chemical spray pyrolysis (CSP) technique. At first the
influence of various spray parameters like substrate temperature, spray rate,
precursor ratio etc. on the opto-electronic properties of CZTS films will be
studied in detail. Then the fabrication of CZTS/In2S3 hetero junctions and
various ways to improve the performance parameters will be tried
