In recent decades, organic solar cells have become a very promising option for
photovoltaic technology. Solar cell research has led to the production of
Perovskite-based solar cells whose power conversion efficiency (PCE) has
increased exponentially in recent years reaching values above 20% in 2016. In
this work, Perovskite (CH3NH3PbI3) tandem type solar cells were elaborated with
the following conformation: ITO / PEDOT: PSS / Perovskite / PC71BM / FM. The
effect of different parameters on the morphology, uniformity and crystallinity
of these films was studied. In addition, the relation between the photovoltaic
behavior of the cells and the morphology of the active layer (perovskite) was
analyzed. The perovskite perovskite-1 (deposited with open lid of the spincoating)
and perovskite-2 films (deposited with closed lid of the spin-coating)
were deposited in a controlled atmosphere (N2) followed by a chlorobenzene
bath, it was observed a granular type crystallization was formed in both cases
and also during the manufacturing process a change of color in the films. In the
perovskite-1 film a more defined and uniform grain type is observed through
the film obtaining better crystallization and homogeneity compared to
perovskite-2. The thickness of both films allowed light absorption with good
performance of a photovoltaic device, obtaining efficiency of 1.94% with an open
circuit voltage of 0.51V and a fill factor of 0.24.
