研究実績の概要

The following manuscript, published in Journal of Physical Chemistry C, was generated as a result of this work.

A general polymer, poly(methyl methacrylate) (PMMA) is utilized as a unique templating agent for forming crack-free mesoporous TiO2 films by a sol-gel method. The pore morphologies were found to be controllable by varying the amount of PMMA. The PMMA-mediated mesoporous TiO2 layer has been applied for the first time to perovskite solar cells exhibiting a best power conversion efficiency of >= 14%, which is ca. three times higher than that using a TiO2 layer prepared by the same sol-gel method without the polymer addition (5.28%). Remarkably, it was superior to the reference device with mesoporous TiO2 layer prepared with conventional nanopartide paste (13.1%). Such mesostructure-tuned TiO2 layers made by the facile sol-gel technique with a commercially available polymer additive has the great potential to contribute significantly toward the development of low-cost, highly efficient perovskite solar cells as well as other functional hybrid devices.
This research is an outcome from the proposed activity of generating a conductive porous electrode using a polymer template and thereafter burning the material to produce a inorganic support with trace carbons.
The research outcome of generating a support for high level supercapicitors is still underway. However the very high performance of optoelectronic device demonstrated in this paper and using our electrodes, suggests a high future potential for this low-cost material processing route.
