What is it about?
Perovskite solar cells have emerged as a promising technology for low-cost, high-efficiency photovoltaic energy conversion. However, their long-term operational stability remains a critical challenge. In this study, we introduce N-[(3-dimethylamino)propyl]methacrylamide as an ionic additive into the perovskite precursor solution. Our findings demonstrate that this additive significantly enhances the thermal and environmental stability of perovskite films by passivating defects and improving the morphology of the material. This advancement paves the way toward the development of more durable and commercially viable perovskite solar devices.

Why is it important?
The rapid degradation of perovskite materials under ambient conditions has limited their large-scale deployment in solar energy applications. Our research addresses this limitation by providing a cost-effective and easily implementable strategy to reinforce the stability of perovskite solar cells. This work contributes directly to the realization of commercially competitive perovskite photovoltaics, thereby accelerating the transition to sustainable energy sources.
Perspectives
From a personal viewpoint, I believe that introducing functionalized ionic additives represents a strategic route to overcoming intrinsic weaknesses in perovskite materials. Beyond its immediate impact on device stability, this approach opens up new possibilities for fine-tuning the optoelectronic properties of hybrid perovskites through molecular engineering.
