In Sentaurus TCAD, how can I define thin film RayTraceBC conditions on a device surface without declaring the outside air in sde?

I'm using Sentaurus TCAD to simulate thin film solar cells in two dimensions. Using the natively one-dimensional TMM solver produces some convergence difficulties: presumably a single dimensional...
