Abstract

The potential of solar cells have not been fully tapped due to lack of energy conversion efficiency. There are three importance mechanisms in producing high efficiency cells to harvest solar energy; reduction of reflectance, light trapping in the cell and higher light absorption. The work presented in this paper shows studies conducted in surface texturisation of single crystalline silicon solar cells using wet chemical etching techniques. Two etching types are applied; alkaline etching (KOH:IPA:DI) and acidic etching (HF:HNO3:DI). The alkaline solution resulted in anisotropic profile that leads to the formation of inverted pyramids. While acidic solution formed circular craters along the front surface of silicon wafer. This surface modification will leads to the reduction of light reflectance from the surface and thereby increases the short circuit current and conversion rate of the solar cells.
