Efficiency of TiO2/Peroviskites/Cu2O Solar Cells with Optimal Thickness at Varying of Environment Temperature

Abstract

Abstract Perovskite solar cells become another field for conventional solar cells achieving an output of 22.1 percent in eight years (2008-2016) short period. There is reason to believe that PSCs are a strong competitor in the photovoltaic field with silicone and CIGS solar cells. The well understanding of the operation mechanism of PSCs is essential and mandatory to furtherly improve device performance. The shape and excitation type is like to inorganic semiconductor solar cells. This work is concerned about the design and studies of lead-based perovskite solar cell model with the flexible architecture of ITO/TiO2/CH3NH3PbI3/Cu2O/Au and analyzed using the solar cell capacitance simulator (SCAPS-1D), we study the effects of the thicknesses for all active materials which are ETM, HTM and Perovskites in addition to environment temperature on the main parameters of our device solar cells. Method/Analysis: Solar cell device assessment is conducted using a Solar Cell Power Simulator(SCAPS). This is a computer-based software tool and is well equipped to conduct research into photovoltaic structures with barriers to homo and heterojunctions, multi-junctions, and Schottky. This model optimizes various parameters such as the thickness, Electron Transport Material (ETM) (ND and NA) doping concentrations, and Hole Transport Material (HTM). Achievement and simulates electrons and holes based on the Poisson’s and continuity equation The effected thickness of CH3 NH3 PbI3 different from 0.2μm to 1μm and the finest results are observed at 0.2μm. Improvements: Efficiency is constant at different temperatures when using the finest thickness for the material where the efficiency reached 21%.
