AI Article Synopsis
- Perovskite solar cells (PSCs) have made great progress in efficiency and stability, but improving these aspects remains challenging.
- The study introduces a functional additive called 3-mercaptopropyltriethoxysilane (SiSH), which helps reduce film stress, decrease defects, and prevent lead leakage in PSCs.
- Implementation of SiSH has increased power conversion efficiency from 20.80% to 22.42% and improved device stability, while also utilizing new adsorbents to address lead leakage for environmental safety.
Article Abstract
Perovskite solar cells (PSCs) have achieved huge success in power conversion efficiency (PCE) and stability. However, further improving the PCE of PSCs and stability is still a big challenge. Here, we attempt to improve the PCE and stability of PSCs using a functional additive named 3-mercaptopropyltriethoxysilane (SiSH) in the perovskite antisolvent. It is revealed that SiSH can release the stress in the film, reduce the defects, and inhibit lithium-ion migration and lead leakage. As a result, the target device achieves an efficiency enhancement from 20.80 to 22.42% as compared to the control device. Meanwhile, device stability is ameliorated after SiSH modification. Furthermore, new adsorbents are used to treat the leaked lead to make it comply with safe drinking water standards. This work provides an idea for developing multifunctional antisolvent additives and adsorbents for high PCE, long stability, and environment-friendly Pb-based PSCs.
