Abstract
CIGS (CuInxGa1-xSe) thin film solar cell has been considered to one of the most promising ways to convert sunlight into electrical energy due to its high efficiency as well as high durability. However, the current vacuum based processes have several drawbacks in manufacturing costs as well as efficiency of resource material use. To solve the problems of the current CIGS thin film synthetic methods, non-vacuum processes have been suggested including printing, electroplating, spraying, etc. Herein, we suggested a synthetic method of CIGS nanoparticles which can be used in the fabrication of CIGS thin films via printing methods. Particularly, in our method the stoichiometric CIGS nanoparticles were synthesized at low temperature (<150℃) using alcohol and volatile solvent. The details of synthetic method and characterization of the CIGS nanoparticles will be presented.
