Formamidinium tin-based perovskite with low Eg for photovoltaic applications

Author affiliations

Abstract

A lead-free low bandgap organic–inorganic hybrid perovskite, formamidinium tin iodide, is utilized as a light absorbing layer in photovoltaics. This material has a bandgap of 1.41 eV which allows light harvesting from the near infrared region, making high photocurrents achievable. A power conversion efficiency of 2.10% was accomplished upon incorporating SnF2.
