Thermal evaporation method was used for deposition of these layers. The results show that SnO2 layers have high electrical resistivity and reflection at 550 nm. With embedding Ag layer, electrical resistivity and reflection of layers decrease. The decreased reflectance accompanied with the enhance transmittance makes these layer suitable as transparent electrode and anti-reflection layers in solar cells. We also observed that band gap decreases with embedding Ag layer that can be described by many-body effects. LA eng UL http://opsi.ir/article-1-146-en.html M3 ER -
