Abstract
In this paper, we report an investigation into the effect of the surface texturing on the efficiency of c-Si solar cells. In order to investigate the effect of the texture, solar cells were fabricated with various textured surfaces by using conventional anisotropic etching with a mixture of KOH and isopropyl alcohol, reactive ion etching, and Ag-catalyzed etching. The reflectances of the textured surfaces ranged from 9.11% to 1.47% at wavelengths between 400 and 1000nm. However, the efficiencies of cells ranged from 15.83% to 17.78%. The observed changes in cell efficiency for surfaces with different textures were due to changes in the doping profile.
