    Fabrication of Dye-Sensitized Solar Cell Modules by Screen-Printing

    , M.Sc. Thesis Sharif University of Technology Chalangar, Ebrahim (Author) ; Taghavinia, Nima (Supervisor)
    Abstract
    Dye-sensitized solar cells (DSSCs) are emerging as low-cost alternatives to conventional, solid-state, silicon solar cells. A porous network of a nanosize semiconductor material with a wide band-gaps usually TiO2, serves as charge transport medium. A monolayer of dye is chemically adsorbed on this material. Photoexcitation of dye causes injection of electrons into the conduction band of TiO2 from where they diffuse towards a transparent conducting oxide (TCO) substrate. The dye is regenerated through receiving electrons from a redox couple dissolved in the electrolyte. After passing through a desired load, the electrons enter the cell through a counter electrode to reduce the redox ions and... 

    Anti-solvent-free Deposition of Perovskite Layers for Fabricating Module Scale Solar Cells

    , M.Sc. Thesis Sharif University of Technology Abdizadeh, Karim (Author) ; Nemati, Ali (Supervisor) ; Taghavinia, Nima (Supervisor)
    Abstract
    Perovskite solar cells with 25.5% efficiency and fast and cheap manufacturing process are among the most promising technologies in this field to replace silicon cells. Despite the challenges of stability and toxicity to these cells, their manufacturing technology has recently shifted to the development of large-scale manufacturing methods in module dimensions. In the present study, the fabrication of perovskite cells in large dimensions to achieve the perovskite module has been aimed and studied that to achieve this, the method of large-scale spraying and printing using the vacuum system was used to create cell-forming films and, consequently, to make the final cell and module. To...
