Novel multi-junction structured solar cells using silicon and germanium are developed, with using sputtering hetero-epitaxy of germanium on silicon. By making use of germanium layer, photons with wavelength between and nm which is used to be difficult for silicon film can be absorbed in excess.
Further breakthrough of energy conversion efficiency in silicon based solar cells is expected. Nanoscaled metals and semiconductors have special properties relative to the bulk. Although highly efficient solar cells utilizing nanostructures are being proposed, conventional nanotechnology cannot afford to manufacture these devices on a large scale.

Selective preparation of novel high performance anodic material for metal secondary battery using TCNF with unique nano-gate structure is studied, which contains target metal only inside of TCNF and does not let metal particle but only metal ion allow to enter and leave inside space of TCNF through nano-gate structure. Such metal charged TCNF with unique nano-gate structure can suitably allow the very effective anodic material for metal secondary battery with high capacity, high rate and high reliance. For the 1st stage, the optimization of nano-gate structure of TCNF, the charge of target metal to only inside of TCNF-NG and the proper electrochemical charge-discharge characteristics of target metal ions through the nano-gate structure are focused to early realize the anodic materials for Li and Na metal secondary battery systems.

Light emitted from the sun and waste heat produced from human activities are precious energy sources in our country which lacks any other energy resources. Photovoltaics and thermoelectrics are the technologies that convert these energies into electric power, but seem to run into an impasse technologically at present.
We try to unify the two technologies and create a new science on optically-active thermoelectric materials in which light energy and heat can be converted into electric power at a much higher efficiency than the state-of-the-art technologies. Using such materials we propose a new direction to developments of energy conversion materials. We are wasting huge thermal energy, which remains in hot water of baths, automobile exhaust, unused heat from power plants and incinerators, for instance.
This research aims to develop novel thermoelectric materials, which harness the remaining heat to generate electricity.

By clarifying the further mechanism of electron storage, device structure and material processing are optimized. Si is one of the powerful candidates for next-generation anode materials for rechargeable lithium-ion batteries.
However, a large volume expansion of Si upon Li insertion can totally destroy the structure of the whole electrode, resulting in a quite poor cyclability. In this work, we overcome this problem by using Li22Si5 alloy as an anode material.
