Thoughts on Future Directions of
Thin-Film Solar Cell Research and
Development
12.1 Introduction
This topic presented the advances that took place in thin-film solar
cells area, especially during the first decade of the 21st century.
All conclusions were made based on experimentally observed
results and their scientific interpretations. The main impact is from
the understanding of material issues and the underlying physics
behind these complex devices. Based on these results and new
understanding, this final short chapter presents new areas to focus
on, to progress in photovoltaic research and development.
12.2 Areas for Research and Development Efforts
12.2.1
Dealing with Defects in Thin-Film Device Structures
As presented in chapters 4, 5, and 11, thin-film solar cells are
severely affected by a set of defect levels present in the device
