The fundamental concept of the book is to explain how to make
thin film solar cells from the abundant solar energy materials by
low cost. The proper and optimized growth conditions are very
essential while sandwiching thin films to make solar cell otherwise
secondary phases play a role to undermine the working function of
solar cells. The book illustrates growth and characterization of
Cu2ZnSn(S1-xSex)4 thin film absorbers and their solar cells. The
fabrication process of absorber layers by either vacuum or
non-vacuum process is readily elaborated in the book, which helps
for further development of cells. The characterization analyses
such as XPS, XRD, SEM, AFM "etc.", lead to tailor the physical
properties of the absorber layers to fit well for the solar cells.
The role of secondary phases such as ZnS, Cu2-xS, SnS "etc.", which
are determined by XPS, XRD or Raman, in the absorber layers is
promptly discussed. The optical spectroscopy analysis, which finds
band gap, optical constants of the films, is mentioned in the book.
The electrical properties of the absorbers deal the influence of
substrates, growth temperature, impurities, secondary phases "etc."
The low temperature I-V and C-V measurements of Cu2ZnSn(S1-xSex)4
thin film solar cells are clearly described. The solar cell
parameters such as efficiency, fill factor, series resistance,
parallel resistance provide handful information to understand the
mechanism of physics of thin film solar cells in the book. The band
structure, which supports to adjust interface states at the "p"-"n"
junction of the solar cells is given. On the other hand the role of
window layers with the solar cells is discussed. The simulation of
theoretical efficiency of Cu2ZnSn(S1-xSex)4 thin film solar cells
explains how much efficiency can be experimentally extracted from
the cells.
One of the first books exploring how to conduct research on thin
film solar cells, including reducing costsDetailed instructions on
