Message
Our research group was kicked out in Oct. 2011 for proposing and demonstrating
concepts of novel semiconductor devices. Noting that equipments for producing
higher electrical powers with smaller environmental load and lower costs
are strongly sought for so as to realize greener society,we have defined
our research target as demonstrating the potential of solar cells composed
of mechanically-stacked subcells, or hybrid tandem solar cells, as a candidate
for third-generation photovoltaic devices with overwhelming high efficiency
(>50%). We are proceeding on research by developing and integrating
all aspects of relevant technologies (semiconductor device fabrication,
characterization,and so on) in combination with fundamental sciences such
as physics and electronics.
We announce with sincere gratitude that we receive supports from a large
number of institutes and companies. In particular we thank to "Development
of high performance and reliable PV modules to reduce levelized cost of
energy" Project of New Energy and Industrial Technology Development
Organization (NEDO) and "Creative Research for Clean Energy Generation
Using Solar Energy" Project in Core Research for Evolutional Science
and Technology (CREST) programs of Japan Science and Technology Agency
(JST) for their financial supports.
