Welcome to the International Symposium on Solar Energy Materials

On behalf of the organizing committee, the chairperson of the International Symposium on Solar
Energy Materials, which will be held on January 25-26, 2019, welcomes you in Kobe. The international
symposium is one of the international symposiums to commemorate the 100th anniversary of KONANGAKUEN and is sponsored by The Hirao Taro Foundation of KONAN GAKUEN for Academic Research.
The objective of the symposium is to provide a platform for lectures, presentations, and discussions
on materials and systems relating to conversion and storage of solar energy. Utilization of solar energy is
one of the most important and promising technologies for enabling sustainability of human society andenvironment, both of which are endamaged by the ever increasing exploitation of fossil fuels and, as aresult, the surge of carbon dioxide content in the atmosphere. The contributions of the International
Symposium cover a wide range of topics relating to conversion and storage of solar energy, which include
newly developed solar cells, novel processes and materials for solar cells, methods and materials forconversion of solar energy into chemical energy, physical and chemical characterizations ofphotofunctional compounds, feature applications and aspects of photovoltaic systems. We, the organizing
committee, believe that state-of-the-art research results and lively discussion will stimulate further
international collaboration between researchers.
This program booklet incorporates abstracts of plenary, keynote, invited, and contributed ones,
which are going to be presented at the International Symposium. We hope that all activities of theInternational Symposium will become both valuable and enjoyable.
