In this work, the effect of some parameters on tin-based perovskite (CH3NH3SnI3) solar cell were studied through device simulation with respect to adjusting the doping concentration of the perovskite absorption layer, its thickness and the electron affinities of the electron transport medium and hole transport medium, as well as the defect density of the perovskite absorption layer and hole mobility of hole transport material (HTM). A device simulator; the one-dimensional Solar Cells Capacitance Simulator (SCAPS‑1D) program was used for simulating the tin-based perovskite solar cells. The current-voltage (J-V) characteristic curve obtained by simulating the device without optimization shows output cell parameters which include; open circuit voltage (Voc) = 0.64V, short circuit current density (Isc) = 28.50mA/, fill factor (FF) = 61.10%, and power conversion efficiency (PCE) = 11.30% under AM1.5 simulated sunlight of 100mW/cm2 at 300K. After optimization, values of the doping concentration, defect density, electron affinity of electron transport material and hole transport material were determined to be: 1.0x1016cm-3, 1.0x1015cm-3, 3.7 eV and 2.3 eV respectively. Appreciable values of solar cell parameters were obtained with Jsc of 31.38 mA/cm2, Voc of 0.84 V, FF of 76.94% and PCE of 20.35%. when compared with the initial device without optimization, it shows improvement of ~1.10 times in Jsc, ~1.80 times in PCE, ~1.31 times in Voc and ~1.26 time in FF. The results show that the lead-free CH3NH3SnI3 perovskite solar cell which is environmentally friendly is a potential solar cell with high theoretical efficiency of 20.35%.

Metal halide-perovskite solar cells have managed to attain soaring heights in power conversion efficiency in the past decade, rising from 3.8% to around 24% in 2019. Formal lead-based perovskites have captivated massive attention because of their then toxic nature and short-term stability of fabricated devices. Therefore, lead-free perovskites have drawn the researcher’s interest in recent years. In this work, we projected a unique planar perovskite structure constituted of [Formula: see text] Tungsten Disulfide [Formula: see text] lead-free perovskite[Formula: see text]. Herein, Tungsten Disulfide (WS2) acts as an electron transport layer (ETL) due to its excellent electron transport capability. The cuprous oxide is used as a hole transport layer (HTL) due to its perfect band alignment with perovskites. The proposed structure is quantitatively analyzed using a solar cell capacitance simulator. The simulation carried out revealed that tin halide perovskite (CH3NH3SnI3) is having the great potential to be an absorbent layer. The proposed configuration demonstrated excellent power configuration efficiency (PCE) of 23% at an optimized thickness of different segments. The impact of neutral defect density and position of defect energy level with respect to active layer on device performance was quantitatively analyzed. The results showed that values of performance parameters ([Formula: see text], FF, [Formula: see text] and PCE) of proposed device configurations are drastically reduced with increasing the total defect density of interfacial and perovskite layers. These simulated results will help the researchers working in the specific area of lead-free perovskite solar cell (LFPSC) fabrication.

Perovskite solar cells have become a hot topic in the solar energy device area due to high efficiency and low cost photovoltaic technology. However, their function is limited by expensive hole transport material (HTM) and high temperature process electron transport material (ETM) layer is common device structure. Numerical simulation is a crucial technique in deeply understanding the operational mechanisms of solar cells and structure optimization for different devices. In this paper, device modelling for different perovskite solar cell has been performed for different ETM layer, namely: TiO2, ZnO, SnO2, PCBM (phenyl-C61-butyric acid methyl ester), CdZnS, C60, IGZO (indium gallium zinc oxide), WS2 and CdS and effect of band gap upon the power conversion efficiency of device as well as effect of absorber thickness have been examined. The SCAPS 1D (Solar Cell Capacitance Simulator) has been a tool used for numerical simulation of these devices.

Halide based perovskite offers numerous advantages such as high-efficiency, low-cost, and simple fabrication for flexible solar cells. However, long-term stability as well as environmentally green lead-free applications are the real challenges for their commercialization. Generally, the best reported perovskite solar cells are composed of toxic lead (Pb) and unstable polymer as the absorber and electron/hole-transport layer, respectively. Therefore, in this study, we proposed and simulated the photovoltaic responses of lead-free absorber such as cesium titanium (IV) bromide, Cs2TiBr6 with dopant free electron phenyl-C61-butyric acid methyl ester (PCBM), and dopant free hole transport layer N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (NPB) for the Ag/BCP/PCBM/Cs2TiBr6/NPB/ITO based perovskite solar cell. After comprehensive optimization of each layer through vigorous simulations with the help of software SCAPS 1D, it is observed that the proposed solar cell can yield maximum power-conversion efficiency up to 16.85%. This efficiency is slightly better than the previously reported power-conversion efficiency of a similar type of perovskite solar cell. We believe that the outcome of this study will not only improve our knowledge, but also triggers further investigation for the dopant and lead-free perovskite solar cell.

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.

Inorganic-organic mesoscopic solar cells become a promising alternative for conventional solar cells. We describe a CH3NH3PbI3 perovskite-sensitized solid-state solar cells with the use of different polymer hole transport materials such as 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene (spiro-OMeTAD), poly(3-hexylthiophene-2,5-diyl) (P3HT), and poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7). The device with a spiro-OMeTAD-based hole transport layer showed the highest efficiency of 6.9%. Interestingly, the PTB7 polymer, which is considered an electron donor material, showed dominant hole transport behaviors in the perovskite solar cell. A 200 nm thin layer of PTB7 showed comparatively good efficiency (5.5%) value to the conventional spiro-OMeTAD-based device.

Simulation has been done using SCAPS-1D to examine the efficiency of CH3NH3SnI3-based solar cells including various HTM layers such as spiro-OMeTAD, Cu2O, and CuSCN. ZnO nanorod array has been considered as an ETM layer. Device parameters such as thickness of the CH3NH3SnI3 layer, defect density of interfaces, density of states, and metal work function were studied. For optimum parameters of all three structures, efficiency of 20.21%, 20.23%, and 18.34% has been achieved for spiro-OMeTAD, Cu2O, and CuSCN, respectively. From the simulations, an alternative lead-free perovskite solar cell is introduced with the CH3NH3SnI3 absorber layer, ZnO nanorod ETM layer, and Cu2O HTM layer.

Research in solar cells is needed to maximize Indonesia’s vast solar potential that can reach up to 207.898 MW with an average radiation of 4.8 kWh/m2/day. Organometallic perovskite solar cells (PSCs) have gained immense attention due to their rapid increase in efficiency and compatibility with low-cost fabrication methods. Understanding the role of hole transport layer is very important to obtain highly efficient PSCs. In this work, we studied the effect of Hole Transport Layer (HTL) to the performance of perovskite solar cell. The devices with HTL exhibit substantial increase in power conversion efficiency, open circuit voltage and short circuit current compared to the device without HTL. The best performing device is PSC with CuSCN as HTL layer, namely Voc of 0.24, Isc of 1.79 mA, 0.27 FF and efficiency of 0.09%.
