Theoretical Investigation of a Dye Solar Cell Wrapped Around an Optical Fiber

Dye solar cells (DSCs) are a complementary type of solar cell devices, and particularly interesting because they can be assembled in new and more exotic architectures compared to conventional solar cells. These systems need to be simulated preserving the real geometry of the device. In this paper, we use a 3-D model of DSCs implemented using finite element method to simulate DSCs wrapped around an optical fiber. We focus on the investigation of the electrical behavior of the cell by changing three important aspects: the counter-electrode contact, TiO₂ thickness and light coupling between the optical fiber and the active porous material in the cell.
