| Outline of Final Research Achievements |
To improve the efficiency of organic photovoltaics, a light management technology by which the spatial distribution of reflective index is controlled with 3-dimensional nanostructures has been developed. In the study concerning a device that integrates a moth-eye nanostructure and high-refractive-index glass, it has been demonstrated from both optical simulations and experiments that a highly efficient light trapping has been achieved in a wide spectral region. In addition, a functional multi-layer coating on a moth-eye surface has been numerically examined to obtain a basis of the technique for enhancing the stability of antireflective performance.
