6th Workshop on the Future Direction of Photovoltaics
1-2 March 2010, at Aogaku Kaikan in Tokyo, Japan
Scope of Workshop: Further development in the science and technology of photovoltaics is required in order to realize
the Roadmap PV2030 plus 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
and future of solar cells, materials and industrial technologies.
Organized by:

The Japan Society for the Promotion of Science,
The 175th Committee on Innovative Photovoltaic Power Generating Systems
