Article Synopsis
- The study focuses on improving the efficiency and stability of CHNHPbI perovskite films for solar cells by controlling nucleation through the addition of 4-tert-butylpyridine (tBP).
- tBP helps to suppress nucleation and forms an intermediate phase, resulting in high-quality perovskite layers as confirmed by in situ optical microscopy and X-ray diffraction patterns.
- The treated perovskite achieved a power conversion efficiency (PCE) of 17.41% and maintained over 89% of its initial PCE after 30 days at room temperature, indicating significant improvements in both efficiency and stability.
Article Synopsis
- To improve perovskite solar cells (PSCs), the researchers optimized the structure and movement of carriers in perovskite films using carbon (C) as nucleation sites in the precursor solution.
- The addition of C helps lower the energy needed for nucleation, enhancing the interaction between lead iodide (PbI) and organic materials, which improves film quality.
- The resulting PSCs achieved a power conversion efficiency of 18.33% and showed excellent durability, with minimal efficiency loss when exposed to high humidity and temperature over extended periods.
