 , combined with low-cost large-scale storage\, is likely to play a dominan
 t role in decarbonizing the expanding global power sector in the long run.
  For example\, the global deployment of PV is targeted at ~75 TW installed
  capacity by 2050\, from the current (2025) ~2.5 TW. While currently used 
 PV technologies are efficient\, reliable\, and relatively cheap\, there is
 \, and always will be\, insatiable demand for new PV technologies that are
  more efficient and cost-effective\, and importantly\, have a smaller ‘c
 arbon-footprint.’ In this context\, the promising new perovskite solar c
 ells (PSCs) technology\, where the thin-film PV can be mechanically rigid 
 or flexible\, has the potential to meet all those requirements. Also\, lig
 htweight flexible PSCs are more versatile\, where they can be used to powe
 r internet-of-things\, vehicles\, satellites\, portable supplies\, etc. Wh
 ile the record power-conversion efficiency of PSCs now rivals that of conv
 entional silicon PV\, durability and mechanical reliability are becoming 
 ‘bottleneck’ challenges in PSCs. To address these technical hurdles\, 
 several rationally-designed interfacial tailoring approaches are used to e
 nhance the mechanical properties of both rigid PSCs and flexible PSCs. Mos
 t importantly\, these approaches are designed such that they simultaneousl
 y increase both efficiency and durability of PSCs. The important challenge
 s and opportunities\, together with best practices\, pertaining to the thr
 ee key interrelated elements that determine the mechanical reliability of 
 PSCs are discussed: (i) driving stresses\, (ii) mechanical properties\, an
 d (iii) mechanical failure. The scientific rationales for these approaches
  to improve the mechanical properties are also discussed\, together with t
 he presentation of examples where failure-mitigation results in more effic
 ient\, durable\, and reliable PSCs.
