Reliability of Sputtered Aluminum Thin Film on Flexible Substrate Under High Cyclic Bending Fatigue Conditions

Abstract

Aluminum thin films on flexible substrates are very popular as a back electrode in solar photovoltaic technology. However, during their manufacturing and use, the package is subject to cyclic bending, which leads to cracks in the conductive thin film and ultimately failure of the package. This paper investigates the effect of film thickness, bending… (More)
