Effective Front Contact Layer for Physical and Optical Performance of Perovskite Solar Cell

摘要

Modified simple design structure with efficient front contact layer as well as high efficiency of Perovskite solar cell is presented in this paper. Effect of cathode with different metal like Silver, Aluminum and Gold with nano-composite based cathode buffer layer is focused on designing the Efficient Perovskite solar cell. On this basis, an alternative structure is designed by using ZnO as Electron transport layer instead of TiO₂ for better performance. Moreover, SpiroOMeTAD is introduced in addition to high efficiency. 3-D analysis of Perovskite structure, overall performance analysis of Open Circuit Voltage (Voc), Short Circuit Current Density (Jsc), Maximum Power (Pmax), Fill Factor (FF) and Efficiency is calculated. 12.42% efficiency is found with the value 0.47 volts, -365.24 Am^-2 and 74.86 of Voc, Jsc and FF respectively. Furthermore, different physical analysis like graphical comparison among current, applied Voltage, charge density and current density as well as optical simulation of photon absorption, distribution, generation rate, and photon density are performed. This work is ultimately based on the analytical discussion over the designed cell for obtaining high efficiency and cost effective cell by solving the problem of complex structure.
