Frequency Conversion Layers for Si Solar Cell Efficiency Improvement

Abstract : SiNx and SiNx: Tb3+ thin layers deposited by reactive magnetron co-sputtering have been studied with the aim of optimizing the light management in Si solar cells. Those Si-based layers are developed to be compatible with the Si-PV technology. An efficient energy transfer between matrix and terbium ions has been demonstrated and optimized. The layer composition and microstructure as well as its optical properties have been analyzed to favor the required optical properties for achieving a good solar cell, i.e., good anti-reflective properties and high luminescence emission intensity. Finally a Tb-doped SiNx thin film has been deposited on the top of a Si solar cells and solar cell characteristics studied.
