Abstract

Quantum efficiency of long-base n⁺p junction silicon solar cells with a SiO₂ layer deposited on the top of cell, and with one-dimensional gratings etched in the cell's top is considered. It is assumed that the region where the useful absorption occurs is outside the grating region. The efficiency is independently optimized by adjusting the layer depth, and the grating dimensions, respectively. It is shown that optimum efficiency of the cells with grating is higher than that of the cell with SiO₂ layer.
