2nd Workshop on the Future Direction of Photovoltaics
2-3March 2006, 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.
