Perovskite Materials

Abstract In the present study, a topical review of recent advances in the perovskite solar cell (PSC) is discussed in detail. Organolead halide perovskite materials have many qualities to make them suitable for the fabrication of low solar cells. High absorption coefficient, long charge carrier diffusion length, low temperature processing and ambipolar behaviour are the main advantages of perovskite materials. The efficiency of the perovskite solar cell is considerably increased from 3.9-22.1%since 2009. In the present review, firstly, the fundamentals and progress in the field of PSC are discussed. The types and structures of PSC are also discussed. Three are four main layers (electron transport layer (ETL), photo-active layer (perovskite layer), the hole transport layer (HTL) and the back contact (the counter electrode)) present in PSC structure. Each and every layer has their importance and it plays an important role to make a low cost solar cell. So study is also focused on the ETL/HTL free PSC. Although the efficiency of PSC is increasing every year, the reproducibility, stability and large scale production are the main challenges. So, the use of mixed cations in active layer to enhance the power conversion efficiency (PCE) and stability of PSC are also discussed in detail. Pb-free PSCs are also discussed rigorously to make harmless PSC. The processing cost of metal electrode deposition in PSC is very costly. So, the replacement of the metal electrode by some other low cost counter electrode is discussed comprehensively in the present review. Lastly, some future research scope of PSC is also discussed.

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.

The efficiency of MASnI3 based solar cell with various hole transport material (HTM) layers including Spiro-OMeTAD, PEDOT:Pss, and Cu2O is studied. Zinc oxide (ZnO) layer is proposed as electron transport layer for lead-free CH3NH3SnI3 based Perovskite solar cells. The influence of device parameters such as doping level of the active layer, thickness of the CH3NH3SnI3 layer and working temperature is discussed. For optimum parameters of all three structures, efficiency of 24.17%, 24.50%, and 25.36% for PEDOT:Pss, Spiro-OMeTAD, and Cu2O, respectively is achieved. To study the optimized performance of this Perovskite solar cell, SCAPS-1D software is considered.

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.

Abstract Details of an open-source planar perovskite solar cell simulator, which includes ion vacancy migration within the perovskite layer coupled to charge carrier transport throughout the perovskite and adjoining transport layers in one dimension, are presented. The model equations are discretised in space using a finite element scheme, and temporal integration of the resulting system of differential algebraic equations is carried out in MATLAB. The user is free to modify device parameters, as well as the incident illumination and applied voltage. Time-varying voltage and/or illumination protocols can be specified, e.g. to simulate current–voltage sweeps, or to track the open-circuit conditions as the illumination is varied. Typical simulations, e.g. current–voltage sweeps, only require computation times of seconds to minutes on a modern personal computer. An example set of hysteretic current–voltage curves is presented.
