| Abstract | We numerically investigate the effect of surface photonic nanostructures on light trapping in Ge/Si quantum dot (QD) solar cells and ultrathin crystalline silicon (c-Si) solar cells. We clarified that light trapping is enhanced on increasing the dip depth of the surface phonic nanostructure. The enhanced light trapping is due to irreversible light transmission at the surface photonic nanostructure, which causes both reduced surface reflection and enhanced internal reflection. In addition, this irreversible light transmission characteristic is robust against conventional antireflection coating. Our findings indicate that this surface nanostructure exhibits a unique functionality that can lead to significant advances in QD solar cells and ultrathin-film solar cells. |
