Organic photovoltaic cells including metal nanoclusters and Its preparation method

摘要

The present invention relates to a substrate; cathode; An electron transport layer; A photoactive layer; A hole transport layer; And a metal nanoparticle including a metal nanoparticle and a thiolate ligand surrounding the metal nanoparticle between the photoactive layer and the electron transport layer, Provide solar cells. The present invention also provides photovoltaic performance and photoluminescence lifetime superior to solar cells using metal nanoparticles of several tens of nanometers in size by providing a bulk heterojunction solar cell to which a metal nanocluster of several nanometers is applied .
