Hydrogenated microcrystalline silicon (µc-Si:H)-as deposited by PECVD at low temperatures (around 200°C)-can be used to fabricate stable pin-type solar cells with conversion efficiencies over 8 %. The variety of growth forms and microstructural patterns observed for different deposition conditions is described; the requirements to be met by layers for use(More)
The conformations of cyclooctadecane, cyclononadecane, and cycloicosane were generated by a stochastic program that works in conjunction with MM2. The shapes of the rings are analyzed in terms of previous work by Dale and others, and in terms of distributions of energies, torsion angle distributions, and torsion angle sequences. A new shape element called(More)
