Perovskite solar cells (PSCs) are an exciting new class of solar devices which could become both less expensive and more efficient than traditional silicon solar cells. PSCs can be manufactured on flexible substrates, but their properties have been unexplored. We examined how the addition of polyethylene oxide (PEO) affected the evolution of the mechanical and opto-electrical properties of flexible PSCs subjected to increasing bending strains, utilizing SEM, UV-Vis spectroscopy, C-AFM, and resistivity measurements to characterize partial PSC devices with and without PEO. The addition of PEO to the perovskite layer was found to mitigate the formation of cracks in the perovskite layer and to stabilize their optical and electrical properties, which may lead to future bendable PSCs.
