In recent years there was a rapid development in the field of fully-printable carbon based perovskite solar-cells, while an efficiency of 15.6% was reported1. The replacement of the metal counter electrode to a carbon electrode decrease the total cost and improve the stability of the device. Therefore, fully-printable carbon based perovskite solar cells are excellent candidates for commercial production. Perovskite composition have a crucial role in the solar cell performance while the optical and physical properties can be tuned by changing the perovskite components. To date the most efficient perovskite composition is based on multiple cations (MA+, FA+, Cs+ or Rb+) together with a mixture of halides (I- and Br-) demonstrated high efficiency together with long term stability. In this study we investigated the impact of various perovskite compositions containing multi cations MA0.15FA0.85Pb(I0.85Br0.15) on the device photovoltaic parameters (PV) in a three-layered (TiO2/ZrO2/Carbon) mesoporous architecture, by using two steps deposition technique.
