“…Over the decades, researchers have focused on increasing the power conversion efficiency (PCE) of the pollution-free, renewable solar cells, which serve as an alternative to traditional fossil fuels. − With increasing demand for high-PCE of solar cells, perovskite solar cells (PSCs) have gained notable attention owing to their increasingly impressive features like high absorption coefficient, long carrier diffusion length, tremendous bipolar charge mobility, low trap state density, low exciton binding energy, and a tunable bandgap. − The metal halide perovskites are designated by ABX 3 , where A refers to an organic cation, B refers to a metal cation, and X refers to a halogen anion. The cation embraces individual or mixed compositions of methylammonium (MA), cesium (Cs), and formamidinium (FA), whereas the halogen anion embraces individual or mixed compositions of Cl, Br, and I. − …”

Since the conversion efficiency of silicon (Si)-based solar cells stagnates at 26.7% in the literature, extensive research and development activities are carried out on perovskite silicon-based tandem solar cells. However, the presence of lead (Pb) and the instability of perovskite prevent their large-scale implementation in the photovoltaic industry. Therefore, it is important to replace the hazardous material (Pb) in perovskite top cells to design non-toxic perovskite–silicon tandem solar cells. The current work yields much-needed studies to develop a non-toxic perovskite–silicon-based tandem solar cell. For the first time, methylammonium tin mixed halide (MASnI3–x Br x )-based materials are comprehensively investigated and optimized with respect to different halide compositions, absorber layer thickness, and bulk defect density in standalone configurations, followed by the development of a lead-free MASnI2Br1–Si-based tandem solar cell. The transfer matrix method and current matching techniques are used to design the two-terminal monolithic tandem cell, which showed a maximum conversion efficiency of 30.7% with an open circuit voltage (V OC) of 2.14 V. The results outlined in this manuscript will pave the way for the progress of highly efficient, non-toxic perovskite–silicon tandem solar cells.

“…This is a result of the unique advantages of OMH perovskites such as the ease of fabrication, high cost-effectiveness, adjustable band gap, low recombination rate, high carrier mobility and high light absorption coefficients [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. During the last decade PSCs have improved their efficiency noticeably, with the cell performance achieving efficiencies in excess of 25% [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Improving the performance of such devices requires advanced knowledge of charge transport and dynamics within the active layer, which are directly related to the device’s efficiency.…”

IR Spectroscopic Degradation Study of Thin Organometal Halide Perovskite Films

The advantages of IR spectroscopy include relatively fast analysis and sensitivity, which facilitate its wide application in the pharmaceutical, chemical and polymer sectors. Thus, IR spectroscopy provides an excellent opportunity to monitor the degradation and concomitant evolution of the molecular structure within a perovskite layer. As is well-known, one of the main limitations preventing the industrialization of perovskite solar cells is the relatively low resistance to various degradation factors. The aim of this work was to study the degradation of the surface of a perovskite thin film CH3NH3PbI3-xClx caused by atmosphere and light. To study the surface of CH3NH3PbI3-xClx, a scanning electron microscope, infrared (IR) spectroscopy and optical absorption were used. It is shown that the degradation of the functional layer of perovskite proceeds differently depending on the acting factor present in the surrounding atmosphere, whilst the chemical bonds are maintained within the perovskite crystal structure under nitrogen. However, when exposed to an ambient atmosphere, an expansion of the NH3+ band is observed, which is accompanied by a shift in the N–H stretching mode toward higher frequencies; this can be explained by the degradation of the perovskite surface due to hydration. This paper shows that the dissociation of H2O molecules under the influence of sunlight can adversely affect the efficiency and stability of the absorbing layer. This work presents an approach to the study of perovskite structural stability with the aim of developing alternative concepts to the fabrication of stable and sustainable perovskite solar cells.

“…Hybrid perovskites are compound materials manufactured by combining inorganic and organic materials for exploitation of beneficial properties of both materials [19,20]. Since the inorganic and organic materials have, respectively, high electron mobility and high photosensitivity, the hybrid perovskite materials have exclusive properties of high optical absorption and low nonradiative carrier recombination rates, making them outstanding recommendations for use in tandem solar cells [21][22][23].…”

One of the essential challenges of tandem solar cells is designing and adjusting the current-matched tandem structures with high efficiency and stability. Nitride-based wide band gap semiconductors, owing to their high stability and high resistance against the cosmic rays, are appropriate elements to apply as the top cell of tandem solar cells. On the other hand, the organic-inorganic hybrid perovskites are emerging materials with exclusive electronic properties such as tunable band gap, low cost, simple manufacturing process, and efficient charge transport properties, making them capable candidates to be used in tandem layered structures. The aim of this paper is to adjust and optimize the performance of a two-terminal tandem solar cell consisting of InxGa1-xN as the top cell and a FAPbIyBr3-y as the bottom cell. We have studied the effect of different practical parameters such as the indium molar of the top cell, iodine molar of the bottom cell, the thickness of each layer, threading dislocation density of InxGa1-xN, and surface texturing effect on the performance of the two-terminal tandem structure. Because of the prominence of current matching problem in two-terminal tandem structures, we have determined the optimum situation for maximum light harvesting along with the minimum value of current matching factor. In the optimum situation, the current matching factor of 0.15 mA/cm2 leads to the power conversion efficiency of 25.17% for the device.
