We review the field of thin-film silicon solar cells with an active layer thickness of a few micrometers.These technologies can potentially lead to low cost through lower material costs than conventional modules,but do not suffer from some critical drawbacks of other thin-film technologies,such as limited supply of basic materials or toxicity of the components.Amorphous Si technology is the oldest and best established thin-film silicon technology.Amorphous silicon is deposited at low temperature with plasma-enhanced chemical vapor deposition (PECVD).In spite of the fundamental limitation of this material due to its disorder and metastability,the technology is now gaining industrial momentum thanks to the entry of equipment manufacturers with experience with large-area PECVD.
