>Magister Scientiae - MSc / Organic-inorganic lead-based perovskite has exhibited great performance in the past few years.
However, the lead (Pb) embedded in those compounds is a significant drawback to further
progress, due to its environmental toxicity. As an alternative, tin (Sn) based-perovskites have
demonstrated promising results in terms of electrical and optical properties for photovoltaic
devices, but the oxidation of tin ion- from stannous ion (Sn2+) to stannic ion (Sn4+) presents a
problem in terms of performance and stability when exposed to ambient conditions. A more
feasible approach may be in a Pb-Sn binary metal perovskite in pursuit of efficient, stable
perovskite solar cells (PSCs) with reduced Pb-content, as compared to pure Pb- or Sn-based
PSCs. Here, we report on the deposition of a Pb-Sn binary perovskite by sequential chemical
vapor deposition.
