Improvement in stability of perovskite solar cells by adlayer of laser treated FAPbI3 quantum dots
Perovskite solar cells have emerged as a promising technology for renewable energy generation due to their potential of high-efficiency and low-cost fabrication. However, their stability under environmental stressors such as humidity and light exposure remains a critical challenge for widespread commercialization. This study investigates the use of FAPbI3 quantum dots (QDs) synthesized in a colloidal solution as adlayer on top of the FAPbI3 bulk light absorbing layer. Our main findings reveal that incorporating such an adlayer composed of FAPbI3 QDs significantly improves the stability of FAPbI3 films and devices against humidity and light-induced degradation. Furthermore, it is demonstrated that a femtosecond (fs) laser treatment in a colloidal solution provides significant surface modification of FAPbI3 QDs. By using such a treated FAPbI3 QDs as adlayer, the devices exhibit power conversion efficiencies exceeding 20 % with improved stability, highlighting their potential for practical applications. This study offers valuable insights into leveraging QDs and the post laser treatment to enhance the stability and efficiency of FAPbI3 perovskite solar cells within a monomaterial system, paving the way for the development of durable and high-performance photovoltaic devices.
