Nuclear Reaction Analysis of Electronic Materials - Part II: Instability Analysis of a-Si: H Solar Cell Material

The hydrogen content is important to the performance of glow discharge amorphous silicon solar cells. In fact, a-Si:H was one of the first materials studied using the 15N NRA method [1]. However, there are some outstanding issues which must be addressed in order to understand the stability of this material in a stress environment (i. e. thermal annealing, radiation). The low temperature (20 - 400°C) diffusion of hydrogen in this material is also still of interest. Further, an investigation into the effects of doping on the concentration and spatial distribution of hydrogen in a-Si:H solar cell material is required.
