Abstract:


Background: Perovskite sensitized solar cells have attracted photovoltaic researchers due to their outstanding photovoltaic performance and low cost synthesis. The fabrication of perovskite sensitized solar cells (PSSCs) involves the use of methyl ammonium Lead halides family.

Objective: The aim of the present work is fabrication of low cost and efficient Perovskite sensitized solar cell.

Method: First of all methyl ammonium iodide (CH3NH3I) was prepared by mixing 10ml of methylamine and 10ml of HI acid in a round bottle flask. The solution was taken to ice-bath treatment (0°C for 2 hrs) and the resultant product was kept in the oven (60 °C, overnight) for complete vaporization.

Results: This paper describes the synthesis of Perovskite material and fabrication of Perovskite sensitized solar cell making use of chemical route and doctor blading. Various properties like structural, morphological and photovoltaic properties of Perovskite sensitized solar cell has been described.

Conclusion: We have synthesized a novel CH3NH3PbI3 material and characterized it by various experimental techniques. The bandgap of perovskite is determined to be 2.26 eV using UV-Vis absorption spectroscopy. The strucural characterization using XRD shows the formation of pure pervoskite material. A maximum IPCE of 14.6 % is obtained at the 400nm wavelength. The fabricated PSSC using PEO-based solid electrolyte shows stable efficiency of 0.53% at 1 sun condition in the room environment.
