Summary
Flexible perovskite solar cells (f-PSCs) benefit from 2D organic surface treatments. Butylammonium iodide (BAI) treatment enhances both power conversion efficiency (PCE) and mechanical durability in f-PSCs.
Area of Science:
- Materials Science
- Renewable Energy
- Solid-State Physics
Background:
- Flexible perovskite solar cells (f-PSCs) are promising for next-generation electronics.
- Enhancing both power conversion efficiency (PCE) and mechanical durability remains a key challenge.
Purpose of the Study:
- To investigate the impact of 2D organic surface treatments (PEAI, 5-AVAI, BAI) on f-PSC performance and durability.
- To identify optimal surface treatments for improved photovoltaic and mechanical properties.
Main Methods:
- Fabrication of f-PSCs on polyethylene naphthalate (PEN) substrates.
- Application of various 2D organic surface treatments (PEAI, 5-AVAI, BAI).
- Characterization of photovoltaic performance (PCE, voltage losses) and mechanical properties (Young's modulus, bending cycles).
Main Results:
- 2D-BAI and 2D-PEAI treatments minimized radiative voltage losses.
- 2D-BAI treatment significantly increased the Young's modulus of the perovskite layer.
- 2D-BAI treated f-PSCs achieved 19.81% PCE and maintained integrity after 10,000 bending cycles.
Conclusions:
- 2D organic surface treatments effectively enhance both efficiency and durability of f-PSCs.
- BAI emerges as a highly effective treatment for robust and efficient flexible perovskite solar cells.
- This research provides valuable insights for developing advanced flexible electronic devices.
