Cost Efficient Thin Film Photovoltaics for Future Electricity Generation (ThinPV)**
Simulation of the electron density in the breakdown chamber at 5 and 0.8 mbar. Higher densities translate to righter colours. The RF potential was applied to the top edge of the simulated region. The left edge is the symmetry axis, the bottom edge and the cylinder on the left are at ground potential, and the right edge is electric insulation.
At five mbar (top), the breakdown occurs in the smaller gap atop the cylinder on the left, while at 0.8 mbar (bottom) the breakdown occurs in the wider gap to the right. The highest electric fi eld would be right at the corner of the small cylinder, but clearly this has no perceptible effect on the electron density.
