Metal-organic frameworks are a kind of nanostructures that are composed of various linkers and nodes, which can be synthesized according to the type of application and the desired properties. One of the forms used in metal-organic frameworks is the production of nano films from them with different methods and their layers on different surfaces. For this purpose, the metal-organic framework based on TCPP porphyrin was used for the deposation. The method of the structure of the selected metal-metal framework is in situ method in which the metal-organic framework structures are arranged on the surfaces, respectively, to form the first layer of metal-organic structure. In order to investigate the application of this project, the metal-organic framework layered on the surfaces was used in the solar cell domain. To compare the I-V test, which is the main test of solar cells, the number of layers deposited on the desired levels, layers 3, 5 and 7 layered from the metal-organic framework, and the results were investigated. In order to influence the different substrates in the intensity of the current and the generated voltage, two types of sub-layers were investigated: 1) Titanium dioxide substrate 2) Titanium Dioxide-Graphene oxide Doped Nitrogen Substrate. After different laboratory tests on the metal-organic framework structure, it was proved that the in-site synthesis of nanofilms of porphyrin-based metal-organic framework was successfully formed and also after the photovoltaic test of the cell made with the number of different layers of the metal organic framework, as well as 2 types of substrates that have been used, It was found that increasing the number of layers of metal-organic framework from 3 layers to 7 layers, as well as increasing the graphene oxide and nitrogen doped to the structure of titanium dioxide, respectively, increased production current intensity (after increasing the number of layers and increasing the graphene oxide) and increasing The photon absorption wavelength range has increased the cell's ultimate efficiency.
