“…The materials used are TCO (BZO, ZnO and MoO3) act as front contact, TiO2 as Electron Transporting Material (ETM), methyl-ammonium tin iodide (CH3NH3SnI3) as light absorbing layer, spiro-OMeTAD as Hole Transporting Material (HTM), Gold (Au) as back contact and SCAPS simulating software. The simulation parameters of those layers were obtained from previous literature [23][24][25][26][27][28][29][30][31][32][33][34][35] and were tabulated in Table 1. The data can be used to investigate the influence of other factors such as series and shunt resistance, defect density etc on the performance of the tin-based perovskite solar cells in planar configuration.…”

Substrates used in perovskite solar cells as front contact are usually transparent conductive oxide (TCO) to allow light to pass through the device. The dominating TCO employed in perovskite solar cells are indium-doped tin oxide (ITO) and fluorine-doped tin oxide (FTO). However, it is imperative to investigate alternative TCOs due to the scarcity of indium metal, relatively low electrical conductivity and high leakage current in ITO and FTO. In this study, simulation has been carried out using Solar Capacitance Simulator (SCAPS) to investigate the efficiency of methyl-ammonium tin iodide (CH3NH3SnI3) based solar cells including various TCOs such as boron-doped zinc oxide (BZO), molybdenum trioxide (MoO3) and zinc oxide (ZnO). TCO parameters such as thickness, donor concentration and operating temperature were varied to study their influence on device performance. The best device performance was achieved using MoO3 with power conversion efficiency of 25.83 % and Jsc, Voc and FF of 32.44 mA/cm2, 0.979 V and 81.38 % respectively. The work shows the potential of fabricating an improved CH3NH3SnI3 perovskite solar cell with MoO3 as front contact.

“…Currently, 90% of solar cell market belongs to silicon (Si) based solar cells due to various advantages. The theoretical efficiency of solar cells e.g., dye-sensitized solar cells, traditional Si-based solar cells and other types of the solar cells is limited to approximately 30% [8,[9][10]. This is mainly due to i) poor absorption of incident light primarily because of completely transparent surface [5], ii) inappropriate material bandgap [8], and iii) low reflection within the device causing faster recombination of emitted electrons [8,11].…”

Due to increased energy intensive human activities resulting accelerated demand for electric power coupled with occurrence of natural disasters with increased frequency, intensity, and duration, it becomes essential to explore and advance renewable energy technology for sustainability of the society. Addressing the stated problem and providing a radical solution has been attempted in this study. To harvest the renewable energy, among variety of solar cells reported, a composite a-Si/CZTS photovoltaic devices has not yet been investigated. The calculated parameters for solar cell based on the new array of layers consisting of a-Si/CZTS are reported in this study. The variation of i) solar cell efficiency as a function of CZTS layer thickness, temperature, acceptor, and donor defect concentration; ii) variation of the open circuit current density as a function of temperature, open circuit voltage; iii) variation of open circuit voltage as a function of the thickness of the CZTS layer has been determined. There has been no reported study on a-Si/CZTS configuration-based solar cell, analysis of the parameters, and study to address the challenges imped efficiency of the photovoltaic device and the same has been discussed in this work. The value of the SnO2/a-Si/CZTS solar cells obtained from the simulation is 23.9 %.

“…The theoretical e ciency of the different type of solar cells e.g. dye-sensitized solar cells, traditional Si-based solar cells and other types of the solar cells is limited to approximately 30% [6,7] due to poor absorption of total incident light as a lack of completely transparent surface [5], inappropriate bandgap material [6], and low re ection within the device causing faster recombination of emitted electrons [6,8]. As a result, a tandem cell is constructed from single-junction gallium arsenide (GaAs) and multi-junction (up to three p-n junctions) concentrators with different materials to absorb a larger spectrum of incident light [9].…”

Due to the high need for energy generation for today’s electronic devices as well as with the natural disasters occurring at the increased frequency, intensity and duration, it becomes essential to explore this scientific area for the sustainability of the society. The benefit of a composite a-Si/CZTS photovoltaic devices for energy generation has not yet been investigated. Addressing the problem and providing a radical solution has been attempted in this research. This research reports the calculated parameters for the solar cell based on the new arrey of the layers, employing a-Si/CZTS. Adapted a-Si/CZTS configuration-based solar cell, debutant analysis of the parameters, and address the challenges that impeded the efficiency of the photovoltaic device are the chief novelty of this research work.
