Group, University of Tokyo to create the clay as a medium of electrolyte-based dye-sensitized solar cells, and has confirmed that its conversion efficiency up to 10.3%. This is at the “Japan Chemical Society 89th annual spring” (March 2009 27 ~ 30) on release.
The solar cells by the University of Tokyo Research Center for Advanced Science and Technology, Professor Koji Segawa Chair and Associate Professor in the Center of the Group Satoru developed. Electrolyte solar cells are used, including lithium iodide and iodine solution, including clay and to add a homogeneous mixture of substances. Clay Co-Op Chemical for the production of “synthetic montmorillonite STN”. Also referred to as the “layer of organic clay minerals” (nano-clay). Ion in a mixture of stress, such as through the imposition of vibration into a liquid so that it can be placed after a period of time, it solidified into a body (gel), or a “thixotropy.”
By the light side of the electrode (cathode) the FTO, and formed at the electrode of 18μm thick titanium dioxide (TiO2) film. In addition, as a dye-sensitized solar cell is also infected by the general pigment composition of ruthenium complexes “N719″.
Electrolyte changes in the weight ratio of clay to analyze characteristics of solar cells found in the weight ratio of about 10% of the cases, the conversion efficiency can reach 10.3%.
Add clay in the electrolyte are solidified in order to enable the electrolyte, so as to solve type dye-sensitized solar cells usually liquid leakage problem happened. The original material so that solidification of electrolyte because of the main charge - the activities of plasma instability, the existence of low conversion efficiency issues. The conversion efficiency of 10.3% using the same liquid electrolytes.
