Lanthanum and strontium modified bismuth ferrite based perovskites with ultra-narrow band gaps

The wide optical band gaps of ferroelectric perovskite oxides have restricted their light absorbing capacities in the photovoltaic devices. In this work, an ultra-narrow band gap E _g and wide optical absorption across the ultraviolet-visible-infrared sunlight spectrum was achieved in lanthanum and...
