Standpoints
Since our final goal is to demonstrate the validity of concept of the novel
photovoltaics, it is not enough to only show performances of cells with
respective structures. Instead we should go forward along Plan-Do-Check-Action,
or PDCA, spirals for establishing rules governing relations between performances
and parameters of structures that we propose, or scaling rules, and finally
demonstrating that performances of such novel devices are to be precisely
forecast, i.e., a priori designed. Our research is essentially steps for
consolidating standard wafer-process and packaging technologies into heterogeneously-integrated
styles. We believe that in this sense achievements in our research should
be likely to be deployed to other kinds of semiconductor devices and systems
than photovoltaics and to bring about breakthroughs in the entire area
of semiconductor industries.
