This study presents a substrate-dependent investigation ofCuI/Cs₃Sb₂I₉/Nb₂O₅/AgNW multilayer structures for the development of flexible andlead-free perovskite solar cells. In the first step, silver nanowire (AgNW) transparentconductive electrodes were deposited onto various substrates, including flexiblepolymer-based (PEN, Kapton, PI) and rigid glass substrates, using Aerosol Jet Printing(AJP). In the second step, Nb₂O₅ thin films were prepared via the sol-gel method andapplied onto the AgNW-coated substrates using spin coating under previouslyoptimized parameters, followed by thermal annealing. Optical transmittance andelectrical conductivity measurements were performed to evaluate film quality. In thethird step, a Cs₃Sb₂I₉ perovskite solution was synthesized using a sol-gel process andcoated onto the Nb₂O₅/AgNW/substrate stacks, followed by annealing andtransmittance measurements. In the fourth step, a CuI hole transport layer wasprepared by mixing CuI and dipropyl sulfide under an inert atmosphere andsubsequently spin-coated onto the perovskite layers. The resultingCuI/Cs₃Sb₂I₉/Nb₂O₅/AgNW structures on all four substrates were annealed, and theiroptical properties were analyzed. Finally, Ag top contacts were thermally evaporatedonto the CuI surface, and current–voltage (I–V) measurements were conducted toassess the electrical performance. The findings demonstrate the impact of substratetype on the optoelectronic behavior of environmentally friendly, solution-processedsolar cell architectures.
