Abstract:Comparision among Silicon oxide,titanium oxide and Pure Sillicon as ARC in Etching Process
Conclusion:Sillicon oxide is the best ARC,which enhanced 20.6% in short circuit current,decreasing reflection,thus improving efficiency.

Description:
---etching by means of reactive ion etching with SF6, or CHF3,/SF6,. ---Two type of ARC used:
(A)Graphaite Covered with conducting Sic,the graphite acts as base contact of the cells. (B) Graphite encapsulated with insulating Sic- and Si02/SiN/Si02-layers (ONO) leads to solar cells on insulating foreign substrates in Method B,the efficiency was improved by 11%:
future scope:same experiment using wet processing
