CIGS/CIS nanoparticles
Fabrication of current thin film solar cell technology involves costly evaporation techniques and is hindering their mass market adoption. Nanoco has addressed this problem by developing a range of CIGS and CIS (copper indium gallium diselenide, copper indium diselenide) nanoparticles for use in next generation thin film solar cells that can be fabricated using conventional printing techniques.
Nanoco’s versatile CIGS/CIS materials are highly crystalline, mono disperse 4-5nm particles that absorb up to 800nm and are soluble in a range of solvents. Attractive properties of these materials are:
solubility in a range of solvents
conventional printing processes can be used e.g. roll-to-roll, inkjet, screen printing etc.
the elemental ratios within the nanomaterial can be tailored to “fine tune” performance.
Post-printing, these nanoparticulate thin films may be annealed to yield bulk macrocrystaline materials which have properties suitable for high performance thin film solar cells.
