Özet

We present a numerical study of nano-cavities used in solar cells for energy harvesting, by employing surface integral equations based on Maxwell's equations in the frequency domain and an efficient solver based on the multilevel fast multipole algorithm (MLFMA). With the three-dimensional modeling of surfaces, we obtain accurate results to evaluate the performances of different structures for improved power absorption in solar cells. This paper includes a brief description of the developed solver and initial numerical examples on various solar cells involving inverted pyramids and spherical cavities.
