T Perovskite solar cells are becoming a dominant alternative for the traditional solar cells reaching an efficiency of 25.2% in a short span of twelve years (2008-2020). Here, we are going to describe a simple process to 'put a voice on a laser beam' and transmit it over a distance via a perovskite solar cell. This process considered as a fascinating example of amplitude modulation of light using sound vibrations. Therefore, the design and simulation of the perovskite solar cell will be described in details in this work. This design is concerned about the lead-free based perovskite solar cell model with the total proposed structure “Metal contact /PEDOT:PSS/ CH3NH3SnI3/ ZnO/ SnO2:F/ Metal contact”. To study the efficiency and the performances of a solar cell, the use of well-known software so-called SCAPS-1D is undertaken to perform the system simulation. The obtained results show also the influence of the doping level of the HTM layer and absorber layer thickness on the performance of the device. So far, only the simulation part has been validated. Despite the costeffect of the system prototype, however, it could be implemented here in the laboratory as perspective work.

Perovskite Layer

Perovskite solar cells are emerging photovoltaic devices with PCE of above 25%. Perovskite are suitable light absorber materials in solar cells with excellent properties like appropriate band gap energy, long carrier lifetime and diffusion length, and high extinction coefficient. Simulation study is an important technique to understand working mechanisms of perovskites solar cells. The study would help develop efficient, stable PSCs experimentally. In this study, modeling of perovskite solar cell was carried out through Setfos software. The optimization of different parameters of layer structure of solar cell would help to achieve maximum light absorption in the perovskite layer of solar cell. Simulation study is based drift-diffusion model to study the different parameters of perovskite solar cell. Hysteresis is one of the factors in the perovskite solar cell which may influence the device performance. The measurement of abnormal hysteresis can be done by current-voltage curve during backward scan during simulation study. In backward scan, the measurement starts from biasing voltage higher than open circuit voltage and sweep to voltage below zero. The numerical simulation used to study the various parameters like open circuit voltage, short circuit current, fill factor, power conversion efficiency and hysteresis. The simulation results would help to understand the photophysics of solar cell physics which would help to fabricate highly efficient and stable perovskite solar cells experimentally.
