| Outline of Final Research Achievements |
We have investigated waveguide-coupled multistriped orthogonal photon-photocarrier-propagation solar cell. The photons propagate in the direction orthogonal to that of the photo-carriers'. Because of the orthogonality, the new solar cell can optimize the absorption of light and the photo-carrier collection independently. By exploiting the degree of freedom along the axis of photon propagation, we can convert the full solar spectrum into electricity resulting in high conversion efficiency. The solar cell can convert virtually the whole spectrum of black body radiation into the electricity, being a candidate for next generation solar cell with high energy conversion efficiency.
