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.;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, expensive equipments are 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.
