| Outline of Final Research Achievements |
In this project, we had developed efficient solar cell substrates using ultra-highly orderd two-dimensional array of gold nanoparticles, which had already been developed in previous studies. Combination of surface plasmon absorbance (500-550 nm and 650-700 nm) of highly orderd two-dimensional array of gold nanoparticles and dye molecule absorbance leads to effective utilization of sunlight with high efficiency. Furthermore, we showed a possibility of further improving of these developed solar cell substrates by multipled reflection of sunlight.

| Academic Significance and Societal Importance of the Research Achievements |
原発事故により我が国のエネルギー事情は大きく変化を遂げてしまったが、クリーンエネルギーである太陽光発電はその変化を乗り越えられるほどに可能性を秘めている。本研究では、現状では太陽光の利用可能な波長に制限がある太陽光発電の効率を上げるために、表面プラズモン励起や色素を利用することにより太陽光の利用可能波長領域の拡大に努め、我が国のエネルギー事情に一石を投じると考えている。
