1st Workshop on the Future Direction of Photovoltaics
3-4March 2005, at Aogaku Kaikan in Tokyo, Japan
Scope of Workshop: Further development in the science and technology of photovoltaics is required in order to realize the2030PV roadmap in Japan and meet worldwide sustainable energy targets. Ultimately, photovoltaics must substitute fossil
energy sources, thereby solving many of the present global environmental problems.
For the above purpose, the scope of this workshop is to provide an opportunity to review and discuss the present status andfuture of solar cells, materials and industrial technologies.
Structure of Workshop: The idea is to have 60, 40 or 30 minutes presentations by invited speakers from overseas and Japan,
to give an overview of the current technologies and future direction of various solar cells, materials and industrial technologies.
