cu in1 xgax se2 based thin film solar cells
p this book provides valuable contents about the fabrication and characterization of chalcopyrite cu in1 xgax se2 based thin film solar cells and modules . the growth of chalcopyrite cu in1 xgax s1 ysey 2 absorbers buffers window layers antireflection coatings and finally metallic grids which are the sole components of solar cells is clearly illustrated . the absorber which contains multiple elements segregates secondary phases if the growth conditions are not well optimized i.e. the main drawback in the fabrication of solar cells . more importantly the solutions for the growth of thin films are given in detail . the properties of all the individual layers and single crystals including solar cells analyzed by different characterization techniques such as sem afm xps aes tem xrd optical photoluminescence and raman spectroscopy are explicitly demonstrated . the electrical analyses such as conductivities hall mobilities deep level transient spectroscopy measurements etc. provide a broad picture to understand thin films or single crystals and their solar cells . the book clearly explains the working principle of energy conversion from solar to electrical with basic sciences for the chalcopyrite based thin film solar cells . also it demonstrates important criteria on how to enhance efficiency of the solar cells and modules . the effect of environmental factors such as temperature humidity aging etc. on the devices is mentioned by citing several examples . br . illustrates a number of growth techniques to prepare thin film layers for solar cells br . discusses characterization techniques such as xrd tem xps afm sem pl cl optical measurements and electrical measurements br . includes i v c v measurements illustrations br . provides analysis of solar cell efficiency br . presents current trends in thin film solar cells research and marketing
