Comparison of Acid- and Base-Catalysed Sol–Gel Synthesis for the in situ Crystallisation of a Perovskite

Key Points

• Acid-catalysed sol-gel synthesis led to more uniform perovskite crystallisation compared to base-catalysed methods.
• Key evidence showed a reduction in defects, enhancing the stability and performance of ionic liquid materials during crystallisation.
• The approach involved comparative synthesis techniques focusing on the impact of acid and base catalysis in producing perovskites.
• This work highlights the potential for improved material properties through optimized synthesis methods, calling for further exploration of sol-gel techniques.
