Novel Synthesis Of Cigs Nanoparticles For Scalable, Benign Inks For Solution Processed Solar Cells, Jacob Fields, Ryan Ellis, Rakesh Agrawal
The Summer Undergraduate Research Fellowship (SURF) Symposium
One potential production route to high efficiency, low cost, photovoltaics (PVs) which was explored is Copper Indium Gallium Sulfide (CIGS) nanocrystal inks for solution processed PVs. A common CIGS nanocrystal ink synthesis utilizes ligands—molecules attached to the particle surface—for colloidal stability, size control, and shape control. It is desirable to devise a novel synthesis which will incorporate a ligand that allows suspensions in more benign solvents than current methods—a desirable characteristic for large scale production. In order to develop the aforementioned synthesis of CIGS nanoparticles, an optimization study of synthesis parameters was performed. Selection of an appropriate solvent, and sulfur …
