The search for new energy sources is a premise in the scientific community. The
use of solar cells emerges as an alternative for getting renewable energy.
However, the commercial solar panels have the disadvantage of high cost and
energy expenditure applied in their production. The investigation of Perovskites
Photovoltaics has grown a lot because of the efficiency levels obtained with
MAPbX3, nevertheless, these cells have low stability at ambient conditions; so,
in this work, we proposed to replace the MA for a phosphonium cation to
improve the stability of perovskites solar cells. The organic cation used in this
work is part of a series of ionic liquids, this is the tetra-n-octylphosphonium
iodide. The inorganic cation was tested using BiI3 as the inorganic part of the
perovskite compound obtaining stability at ambient conditions for 350 hours.
