Resumo
Organic semiconductor molecules and polymers have been widely studied because they have
morphological and electroluminescent properties that contribute in particular to the
development of new photovoltaic systems. Among the most promising properties for this
application are the high efficiency in the production of load carriers, good conductivity, ease of
manipulation and low cost syntheses, therefore to know the capacity of the active layers for
the production of load carriers and the way they operate in a device, is essential to determine
the application and the advantages that a material can bring to the photovoltaic systems. In
this work we aimed to determinethe photophysical and morphological characteristics of the
combination of an electroluminescent polymer MEH-PPV (Poly [2-methoxy-5- (2-
ethylhexyloxy) -1,4-phenylenevinylene]), an organic electroluminescent molecule, Rubene
(5,6,11,12-tretaphenylnaphthacene) and a hybrid Perovskite semiconductor (CH3NH3SnI_Cl2
and CH3NH3SnI2_Cl), which, when deposited as thin films on the anode of ITO (Tin-doped
Indium Oxide), have their new characteristics studied and the combination can be proposed
as an active layer for the production of hybrid solar cells based on perovskite. Based on the
evaluation of the photophysics of the isolated materials and in solution, thin films layer-by-
layer were prepared by two techniques, self-assembly and spin-coating, where their
morphological and photophysical characteristics were evaluated. The properties of the active
layer composed of the combination of the components were evaluated and the most
promising results were obtained for the perovskite composition containing MEH_PPV deposited
in a monolayer by the spin-coating technique.
