Article Preview

Aiming for potential application in flexible solar cells, electronic transport properties are studied for hydrogenated amorphous silicon thin films on plastic substrates. Intrinsic hydrogenated amorphous silicon layers are deposited on Kapton and Upilex-s polyimide substrates at temperatures of 100°C and 180°C by plasma enhanced chemical vapor deposition (PECVD) system. Layers on 75μm and 125 thick Kapton and on 125 Upilex-s substrates are characterized by dark conductivity and activation energy measurements. It can be concluded that the intrinsic layer on 125μm thick Kapton and Upilex-s plastic both have favorable electrical properties and therefore could be employed as substrate material for flexible solar cells.
