As a consequence of their quantum- and electronically-confined inorganic lattices, molecular 1D lead-iodide perovskites are ill suited to photovoltaic (PV) applications. In order to circumvent these problems, we utilized electron accepting viologen (N,N′-dialkyl-4,4′-bipyridinium) dications incorpor...
