Solar cell technology is a key research area with efforts focused on producing highly efficient, cost-effective, and scalable energy harvesting devices. Graphene is a promising candidate for replacing silicon based solar cells owing to its high electron mobility, chemical inertness, and transparency. Although progress has been made in evaluating graphene's response to UV/Ozone exposure, the complete destruction of graphene and the correlation of number of layers to degradation resistance is still lacking. In the present work, we report the full degradation of single and few layer graphene under UV/Ozone exposure. The sheet resistance was reduced from 434.6 +/- 107.1 for single layer graphene to 56.2 +/- 1.1 for four layers. After 5 minutes of exposure, change in sheet resistance rapidly increased for monolayer graphene while the increase for bilayer and few-layer graphene was relatively small. It was determined that additional layers of stacked graphene beyond bilayer increases the survival time by a factor of 2. These results show that the stacking of graphene leads to better electrical performance along with larger survival rates.
