 h efficiency\, low-cost fabrication\, and lightweight properties\, making 
 them strong candidates for next-generation photovoltaics. However\, their 
 instability under environmental stressors hinders commercialization. This 
 thesis addresses PSC stability through advanced encapsulation\, interfacia
 l engineering\, and machine learning. A two-part epoxy encapsulation strat
 egy—using UV-curable and edge-sealing resins—enabled outdoor operation
  with nearly 100% retained efficiency over 1500 hours in Spain\, Israel\, 
 and Germany. Incorporating 2D MXene interlayers at the perovskite/hole tra
 nsport interface improved charge extraction and operational durability. Da
 ta from over 100 devices were used to train machine learning models that p
 redict long-term outdoor stability from accelerated indoor tests\, offerin
 g a novel AI-driven framework for performance forecasting. Impedance spect
 roscopy combined with maximum power point tracking revealed that increased
  ionic conductivity under low light conditions correlates with reduced shu
 nt resistance and faster degradation. Finally\, triple-cation PSCs tested 
 in the stratosphere (–32°C to +32°C\, high UV\, low pressure) maintain
 ed 68–87% of initial efficiency\, validating the resilience of the devel
 oped strategies under extreme conditions. Collectively\, this work demonst
 rates a multifaceted approach to enhancing PSC stability\, paving the way 
 for their reliable deployment in both terrestrial and space-based energy s
 ystems.</p>
