Abstract:
In the present work, the author has designed and developed all types of solar
air heaters called porous and nonporous collectors. The developed solar air
heaters were subjected to different air mass flow rates in order to standardize
the flow per unit area of the collector. Much attention was given to
investigate the performance of the solar air heaters fitted with baffles. The
output obtained from the experiments on pilot models, helped the installation
of solar air heating system for industrial drying applications also. Apart from
these, various types of solar dryers, for small and medium scale drying
applications, were also built up. The feasibility of ‘latent heat thermal energy
storage system’ based on Phase Change Material was also undertaken. The
application of solar greenhouse for drying industrial effluent was analyzed in
the present study and a solar greenhouse was developed. The effectiveness
of Computational Fluid Dynamics (CFD) in the field of solar air heaters was
also analyzed. The thesis is divided into eight chapters.

Abstract:
As emphasis towards sustainable and Renewable energy resources grows world-wide,interest in the capture and use of solar energy is increasing dramatically.Solar cells have been known and used for many years,but depletion of conventional energy resources resulted in the intensification of research on solar cells leading to new design and technique of fabrication.The current emphasis is directed towards high effiency inexpensive solar cells.This thesis includes deposition and characterization of CuInS2 and In2S3 thin films using chemical Spray Pyrolysis(CSP) technique.The optimum condition for these films to be used as absorber and buffer layer respectively in solar cells were thus found out.Solar cell with the stucture,ITO/CuInS2/In2S3/metal electrode was fabricated using these well-characterized films,which yielded an efficiency of 9.5%.
