Abstract
The optical and electrical properties of a new type photonic-plasmonic nanostructure on the back contact of solar cells were investigated numerically through the three-dimensional (3D) finite-difference time-domain (FDTD) method and the Poisson and drift-diffusion (DDCC) solver. The focusing effect and the Fabry-Perot resonances are identified as the main mechanisms for the enhancement of the optical generation rate as well as the short circuit current density. In addition, the surface topography of the nanopattern has a strong effect on the device physics such as the potential and recombination profiles, and therefore influencing the electrode collecting efficiency of the photocurrents.
