摘要

Provided are a method for preparing a light absorption layer for a solar cell, a solar cell including the light absorption layer, and a manufacturing method thereof.The method for preparing a light absorption layer for a solar cell can increase the transport efficiency of charges moving to positive and negative electrodes through the reduction of exciton recombination by spontaneously forming nano aggregates due to a solubility difference of a light absorption material in a good solvent and a poor solvent. In addition, the solar cell can improve photocurrent and photoelectric conversion efficiency by increasing the area of a bonded interface between the light absorption layer and an electron transport layer through the formation of an uneven structure on the surface of the light absorption layer due to the arrangement of the nano aggregates. Furthermore, the method for manufacturing the solar cell can simply and easily manufacture a large-sized high efficiency solar cell using a solution process.
