Kashiwa Sustainability Science Seminar Series 2

Learning from the Japanese PV Technology Specific Innovation Systems
What are the driving forces behind the development of PV technologies in
Japan?

Date: Wednesday, June 4 at 16:30-18:00
Venue: Lecture Room 3, Environmental Building 3F, Kashiwa Campus, University
of Tokyo

Speaker:
Ms. Marjan Prent, Researcher, The Netherlands Office for Science and
Technology
Royal Netherlands Embassy (Webpage: http://www.twanetwerk.nl)

Seminar
Between February and June 2008, Marjan Prent has investigated how the
Innovation Systems of several PV (photo-voltaic) technologies in Japan are
organized, and how they are performing. This seminar will discuss the
initial conclusions from this research and will give insight into which
factors promote and inhibit the development of PV in Japan. Though part of
the research involves a comparison with the Netherlands, the focus of this
seminar will lie on the Japanese analysis.

Introduction
Japan is a frontrunner in the development and implementation of renewable
energy technologies. One of the areas where Japan is highly proficient is in
the field of PV technologies. Many countries, such as the Netherlands, are
very keen to learn more about the innovations that are developed in Japan.
However, they usually overlook the main problem with adopting new
technologies, i.e. that the technology needs to be integrated into an
existing social and technological system. Each technology has its own unique
network of institutions that enables a technological breakthrough to diffuse
successfully in the market. Such systems are often referred to as
‘Technology Specific Innovation Systems’ (TSIS) and include actors such
as: universities, R&D institutes, manufacturers, users, branch
organizations, government, interest groups and financial institutions. On
the basis of Japan’s success rate in developing and implementing PV
innovations, it is safe to assume that the Japanese PV TSIS are well
organized. Countries such as the Netherlands might benefit from learning how
Japanese TSIS function. Therefore, an in-depth study of these Japanese
Systems of Innovation will be of value.

Research
The research is part of a 6-month master thesis research to be completed in
July 2008. The research will also fill in the Japanese part of the “Status
rapport ‘Solar PV (Photovoltaic conversion of solar energy)” of
SenterNovem, the funding agency of the Netherlands Ministry of Economic
Affairs. The objective of the research is to investigate the organization
and performance of several Japanese Energy Innovation Systems in Japan.
After this analysis a comparison will be made between the Dutch and Japanese
systems, which may lead to recommendations to the Netherlands energy sector
how they can speed up the creation and diffusion of PV technologies. In
total 7 PV technologies have been chosen: Solar grade silicon, crystalline
silicon solar cells, thin-film silicon solar cells, stacked silicon solar
cells, CIS solar cells, dye-sensitized solar cells and polymer solar cells.
The TSIS were investigated through interviews with key actors within the
Japanese PV branch, including: manufacturers, suppliers, government
organizations and research institutes. With the completion of the
investigation of the Japanese PV Innovation systems, Marjan Prent will
return to the Netherlands in the beginning of June to complete the
comparison between the Dutch and Japanese systems. To work on

Profile of researcher
Marjan Prent (BSc. Electrical Engineering) is currently finishing her
Master’s Degree in Management of Technology at Delft University of
Technology and is pursuing a Bachelor’s Degree in Languages and Cultures of
Japan at Leiden University. The research in Japan was commissioned by the
Netherlands Office of Science and Technology of the Royal Netherlands
Embassy and is conducted in collaboration with SenterNovem, the Innovation
Systems department of Delft University of Technology and the department of
Innovation and Environmental Sciences of Utrecht University.
