METHOD OF MAKING CU(INGA)SE2 NANOPOWDERS FOR ABSORBER LAYER OF SOLAR CELL

摘要

The present invention relates to a method for manufacturing Cu (InGa) Se ₂ nanopowder for solar cell light absorption layer, and its purpose is to provide a low cost process that does not use high vacuum process for manufacturing CIGS thin film used as light absorption layer of solar cell. The present invention provides a simple and convenient method for directly and directly synthesizing spherical Cu (InGa) Se ₂ (CIGS) nanoparticles.;The composition of the present invention is a method for producing a compound semiconductor by a solvent-heat method, the Cu, In + Ga, Se powder as a raw material in the ethylenediamine (ethylenediamine) in a solvent by molar ratio 1: 1: 2 and reacting spherical It is characterized by producing a CIGS nanopowder.;Solar Cell, Cu (InGa) Se₂, Light Absorption Layer, Rod Nanoparticle, Solvent Thermal Method
