Organic solar cells (OSCs) have been studied actively because of its advantages such as low-cost process, light weight, and easy fabrication. Especially, inverted-OSCs using metal oxide as electron transporting layer (ETL) showed high performance and great stability compared to conventional structure solar cells. Moreover, the performance of i-OSCs can be enhanced by introducing ETL for improving carrier extraction and reducing carrier recombination. Among them, hydrophilic functionalized inorganic interlayer should make a great performance and stability of i-OSCs. In this study, hydrophilic functionalized inorganic material was introduced as an interlayer with metal oxide. I-OSCs were fabricated with and without inorganic interlayer. As a result, performances of i-OSCs device were enhanced in the device fabricated with hydrophilic functionalized inorganic interlayer by means of modifying work function and reducing energy barrier between electrode and active layer. |
