| 제목 | Improved Performance of Inverted Organic Photovoltaics by introducing Electron Transporting Layer with Chelating Agent |
| 초록 | Inverted organic photovoltaics (OPVs) have been reported the power conversion efficiency (PCE) over 12% due to their high internal built-in potential and high stability. Metal oxides are usually introduced as electron transporting layer (ETL) in inverted OPVs because they have better conductivity and higher optical transparency than other materials. However, these ETL have some defects on the film surface such as oxygen vacancies, these defects can cause performance degradation of devices. So, it is essential to remove these defects for achieving high performance devices. Chelating agent is chemical compound that react with heavy metal ions to form stable metal complexes. Therefore, vacancies in ETL can be removed by treatment with chelating agent. In this study, we fabricated OPVs introducing ETL with chelating agent for passivation surface vacancies. As a results, device performances were improved by eliminating the defects existing in the ETL. |
