Reducing\u003C\/p\u003E\u003Cp\u003Etheir weight could make them easier to transport and deploy while lowering demands on\u003C\/p\u003E\u003Cp\u003Esupporting structures. Conventional devices, however, are typically built on heavy, fragile glass.\u003C\/p\u003E\u003Cp\u003ELightweight, conductive substrates offer a promising alternative, but their integration introduces\u003C\/p\u003E\u003Cp\u003Enew interfaces that can limit charge collection, device performance, and stability. This thesis\u003C\/p\u003E\u003Cp\u003Einvestigates how processing and interfacial chemistry influence these properties.\u003C\/p\u003E\u003Cp\u003EThe first research thrust examines perovskite solar cells fabricated on alternative substrates.\u003C\/p\u003E\u003Cp\u003EElectrical measurements reveal limitations in charge collection associated with the substrate\u2013\u003C\/p\u003E\u003Cp\u003Edevice interface. Surface characterization provides insight into the chemical and electronic\u003C\/p\u003E\u003Cp\u003Eproperties responsible for these limitations. Introducing an interfacial modification improves\u003C\/p\u003E\u003Cp\u003Echarge collection, demonstrating the importance of controlling surface properties when integrating\u003C\/p\u003E\u003Cp\u003Elightweight substrates.\u003C\/p\u003E\u003Cp\u003EThe second research thrust explores surface treatments designed to improve electrical contact and\u003C\/p\u003E\u003Cp\u003Esimplify device fabrication. Complementary characterization techniques will investigate how these\u003C\/p\u003E\u003Cp\u003Etreatments affect interfacial composition, bonding, structure, morphology, and electronic\u003C\/p\u003E\u003Cp\u003Eproperties. Device measurements will establish how these changes influence charge collection and\u003C\/p\u003E\u003Cp\u003Eoverall solar cell performance.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee Members:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EProf. Juan-Pablo Correa-Baena (Advisor) \u2013 School of Materials Science and Engineering\u003C\/p\u003E\u003Cp\u003EProf. Ajeet Rohatgi \u2013 School of Electrical and Computer Engineering\u003C\/p\u003E\u003Cp\u003EDr. Tod A.
