Next Generation Thin Films for Photovoltaics: InGaAsN; Preprint

Research output: Contribution to conference › Paper

Abstract

A new semiconductor alloy system, InGaAsN, has been identified as a candidate material for multi-junction solar cells having efficiencies greater than 40%. The introduction of small amounts of nitrogen (~2%) into the InGaAs alloy system greatly reduces the band gap energy, with reductions approaching 0.4 eV for 2% nitrogen content! With the appropriate ratio of indium to nitrogen concentrations,InGaAsN can be lattice matched to GaAs.
