| Summary: | Corruption has appeared throughout the land and sea by (reason of) what the hands of
people have earned so He may let them taste part of (the consequence of) what they have
done that perhaps they will return (to righteousness). [30:41]. Rigorous and over
exploitation of oil reserves have caused multiple destruction to land and sea; both in
exploration and application of oil. Alternative energy source such as solar power is no
longer desirable, it is crucial. 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 carried out shows studies conducted in surface
texturisation of single crystalline silicon solar cells using wet chemical etching techniques.
Two etching types are applied; alkaline etching (K0H:IPA:DI) and acidic etching
(HF:HN03: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 leads to the reduction of light reflectance
from the surface and thereby increases the short circuit current and conversion rate of the
solar cells. The work carried out already won award in ENVEX2010, and produced a paper
in IEEE conference. |
