Design and analysis of antireflection grating structure for solar energy absorber Academic Article uri icon


  • Quantum efficiency of long-base n+p junction silicon solar cells with SiO2 layer deposited on the top 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.
