Preface
cells, current status of polymer cells, carrier generation mechanism, cuttingedge theory on organic solar cells, photo voltage generation, doping and future
development.
I was first approached regarding the writing of a book during a brief discussion
with Claus Acheron, Ph.D., Executive Editor Physics in Springer. This occurred
immediately before my presentation titled “Bandgap Science for Organic Solar Cell”
at the 2015 European Material Research Society in Lille, France. In 2017, I was
again requested to write a book by Shinichi Koizumi, Ph.D., a Senior Editor for
Books Chemistry and Materials Science in Springer. It has taken approximately 2
years to complete this book. I am deeply appreciative of the efforts of my writers,
Hideo Okita, Ph.D., Itaru Osaka, Ph.D., Takatoshi Fujita, Ph.D., Toshihiko Kaji,
Ph.D. and Seiichiro Izawa, Ph.D. I am also very grateful to the Springer editors,
Shinichi Koizumi, and Taeko Sato, for their assistance and encouragement.
It is my strong hope that young scientists of the next generation will greatly
advance the research in this field.
