Halide-perovskite semiconductors have a high potential for use in singlejunctionand tandem solar cells。 Despite their unprecedented rise in power conversionefficiencies (PCEs) for photovoltaic (PV) applications， it remains unclearwhether perovskite solar modules can reach a sufficient operational lifetime。 Inorder to make perovskite solar cells (PSCs) commercially viable， a fundamentalunderstanding of the relationship between their nanostructure， optoelectronicproperties， device efficiency， and long-term operational stability/reliabilityneeds to be established。 In this review， the phase instabilities in state-of-the-artformamidinium (FA)-rich perovskite absorbers is discussed。 Furthermore，the concerted efforts are summarized in this prospect， covering aspects fromfundamental research to device engineering。 Subsequently， a critical analysisof the dictating impact of the nanoscale landscape of perovskite materials ontheir resulting intrinsic stability is provided。 Finally， the remaining challengesin the field are assessed and future research directions are proposed for improvingthe operational lifetimes of perovskite devices。 It is believed that theseapproaches， which bridge nanoscale structural properties to working solar celldevices， will be critical to assessing the realization of a bankable PSC product。
