摘要: In thin-film silicon solar cells, a flexible optical design for light collection is developed that can enhance the path length in absorber layer. this paper, we demonstrate rectangular, trapezoidal and triangular metallic diffraction gratings as back reflectors. The potential of structures cells investigated by means numerical simulations, i.e., Rigorous Coupled Wave Analysis enhanced Modal Transmission Line theory. results show 0-order reflection be suppressed energy transferred to high orders gratings, especially gratings.
