Research groups of Hiroshi Shimizu invitation (Sho wall) researchers of National Institute of Advanced Industrial Science and Technology developed the counter electrode raw material of the dye sensitizing type solar cell that did not use platinum.
The confirmation lingua of showing the same degree of the characteristic as platinum by the raw material that uses carbon nanotube (CNT) of the multi-layer.
It is Iu when leading to the decrease of the manufacturing cost and the technology of making to the large area.
The counter electrode that the research group developed is a structure to place by the electroconductive polymer with the ionic liquid further as for multi-layer CNT.
The polystyrene sulfo aluminium of the imidazole that the ionic liquid and was the electroconductive polymer was sonicated to CNT after the lingua of the hybrid, and centrifuge method Shite was made.
Almost the same value was obtained by characteristics of conversion efficiency and the electric current density, etc. compared with the platinum counter electrode.
The research group excels as a counter electrode raw material that takes the place of platinum in electroconductive, pays attention to CNT that has come to be able to do the quantity synthesis, and has advanced the research.
However, there were difficulties in the formability and the dispersion because there was CNT in powder form.
