Optimization of Chemical Texturing of Silicon Wafers Using Different Concentrations of Sodium Hydroxide in Etching Solution

In this paper, the morphology of chemically etched silicon with various concentration  is reported. The surface of Silicon (100) has pyramidal structures which can be used for anti-reflection applications in solar cells. Pyramidal structures can capture incident sun light therefore can enhance the efficiency of silicon solar cells. The structure of silicon pyramid was studied using scanning electron microscopy (SEM) while the optical properties was investigated by reflectance spectrometer
