摘要： Disclosed are an ink containing nanoparticles for formation of thin film of a solar cell and its preparation method, CIGS thin film solar cell having at least one light absorption layer formed by coating or printing the above ink containing nanoparticles on a rear electrode, and a process for manufacturing the same. More particularly, the above absorption layer comprises Cu, In, Ga and Se elements as constitutional ingredients thereof and such elements exist in the light absorption layer by coating or printing an ink that contains Cu2Se nanoparticles and (In,Ga)2Se3 nanoparticles on the rear electrode, and heating the treated electrode with the ink.According to the present invention, since Cu(In,Ga)Se2, that is, CIGS, thin film is formed using the ink containing nanoparticles, a simple process is preferably used without requirement of vacuum processing or complex equipment and particle size of the thin film, Ga doping concentration, etc. can be easily regulated.

摘要： Disclosed are a solar cell manufactured using a composite thin film comprising amorphous silicon and nanocrystalline silicon, a method of manufacturing the solar cell, and a composition for the composite thin film used in manufacturing the solar cell. More particularly, a silicon semiconductor layer in the solar cell is fabricated by using the composite thin film comprising the amorphous silicon and the nanocrystalline silicon, the composite thin film being formed by dispersing nanoparticles of the crystalline silicon in a liquid silicon precursor and modifying them.The solar cell of the present invention is manufactured by dispersing the crystalline silicon nanoparticles in the liquid silicon precursor, coating the dispersion on a substrate or printing the substrate with the dispersion, and heating the coated or printed substrate to modify the liquid silicon precursor into the amorphous silicon.According to the present invention, any expensive equipment requiring alternative complicated installations is not needed to form a composite thin film comprising both of amorphous silicon and crystalline silicon. In addition, it is possible to form a composite thin film comprising plural materials with different band gap energy which can remarkably improve conversion efficiency of a solar cell by using a liquid precursor and nanocrystalline particles in a solution process with low production cost.
