GWANGJU, South Korea, Sept. 16, 2022 /PRNewswire/ -- Organic solar cells (OSCs), which use organic polymers to convert sunlight into electricity, have received considerable attention in recent times for their desirable properties as next-generation energy sources. These include lightweight, flexibility, scalability, and a high power conversion efficiency (>19%). Currently, several strategies exist for enhancing the performance and stability of OSCs. However, a problem that lingers on is the difficulty of controlling the morphology of the active layer in OSCs when scaling up to large areas. This makes it challenging to obtain high-quality active layer thin films and, in turn, fine-tune the device efficiency.

Key Points: 
  • However, a problem that lingers on is the difficulty of controlling the morphology of the active layer in OSCs when scaling up to large areas.
  • This makes it challenging to obtain high-quality active layer thin films and, in turn, fine-tune the device efficiency.
  • In a recent study, a team of researchers from the Gwangju Institute of Science and Technology, Korea set out to address this issue.
  • The active solution was hydrophobic and, accordingly, the researchers decided to use deionized (DI) water and vortices to stir the solution.
