Lead tin sulfide (PbSnS) nanocrystals: A potential solar absorber material.

We present a new ternary semiconductor absorber material - PbSnS - for solar cells. PbSnS nanocrystals (NCs) were synthesized using the successive ionic layer adsorption reaction (SILAR) process. Energy-dispersive X-ray spectroscopy revealed the Sn ratio for a sample prepared with five SILAR cycles to be x=0.
