This book reviews key aspects of the materials science of solar energy
conversion. The objective is an identification of problem areas in which a
greater engagement of the solid-state physicist will improve existing
technologies.
The involvement of the materials scientist may soon be of decisive
importance. Solar energy conversion will contribute to future energy needs to
the extent that existing devices can be improved in performance and lowered in
cost. On the engineering level, most current approaches have been tried and
perfected over the past 50 years without there being much hope for further
improvements. However, a novel aspect has entered during the last two to three
decades with the rapid development of the physics of solids which through their
optoelectronic properties play a key role in major conversion schemes.
Consequently, the greater involvement of modern solid-state physics will
increase the chances to move solar technology beyond the barrier of economic
marginality that now hinders its progress.
