Abstract :
We have used a new modeling approach for simulation of a-Si:H tandem cells. The trap assisted tunneling model and an enhanced effective extended state mobility were used to model the recombination and transport in the high field region of the tunnel recombination junction. With this approach, realistic tandem cell characteristics could be obtained. We illustrate how modeling can be used for the analysis of multi-junction cells
