The field of metal organic perovskite solar cells has attracted a vast amount of
research mainly because of the accelerated rise in the efficiencies of these
photovoltaic devices. Perovskite ABO3 materials have been studied intensively
in physics, chemistry, and materials science because of their interesting and
technologically important properties, including ferroelectricity,
superconductivity, magnetoresistance, and catalysis. Tandem solar cells and
perovskite solar cells (PSCs) are engineered by using organic and inorganic
materials. Currently the perovskite solar cells use MAPbI3 synthesized by one or
two steps. However, this compound is still very unstable in humid environments
so it has to be worked in dry rooms or controlled atmospheres, in addition to
the toxicity of lead. In this work, in the search for stability and low toxicity of the
material, we replaced the MAPBI perovskite with another containing a halide
(Cl — , Br — ) of another metal (Cs, Sn), we deposited it on layers of TiO2 and MOFs
for finally evaluate its optical properties and its performance as a solar cell.
