Abstract

Nano-crystalline Si films are deposited using multi-hollow plasma CVD. The films have a wide optical band gap of 1.75 eV and a large absorption coefficient similar to those of a-Si:H films. They also have a low initial defect density of 3×1015 cm3 and show high stability against light soaking. These results suggest that nano-crystalline Si films are promising materials for top cells.
