5th Workshop on the Future Direction of Photovoltaics
4-5 March 2009, at Aogaku Kaikan in Tokyo, Japan
Scope of Workshop: Further development in the science and technology of photovoltaics is required in order to realize theRoadmap PV2030 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.
Organized by:

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