“…The large absorption coefficient of the absorber layer is responsible for the gradual increment in J SC with respect to thickness . As stated in the literature, an increase in resistivity in the device due to an increase in perovskite thickness causes a reduction in FF. The lowest value for FF was roughly 62.07%.…”

Due to their enhanced performance and simplicity in manufacturing, scalability, and versatility, lead-halide perovskite-based solar cells (HPSCs) have received much attention in the domains of energy. Lead is present in nature as a poisonous substance that causes various issues to climate and human health and prevents its further industrialization. Over the past few years, there has been a noticeable interest in exploring some alternative lead-free perovskites. However, owing to some intrinsic losses, the performance that may be achieved from these photovoltaics is not up to standards. Thus, for the purpose of efficiency improvement, a comprehensive simulation is required to comprehend the cause of these losses. In the current research, an investigation into how to employ the promisingly efficient lead-free, allinorganic cesium tin−germanium iodide (CsSnGeI 3 ) perovskites as the photoactive layer in HPSCs was performed. Results exhibited a high efficiency of 12.95% with a CsSn 0.5 Ge 0.5 I 3 perovskite thickness of 0.6 μm and a band gap of 1.5 eV at room temperature. High efficiency may be achieved using phenyl-C61-butyric acid methyl ester (PCBM) as an electron transport material because of its favorable energy-level alignment with the perovskite material. The research further tested the perovskite layer thickness and defect density in depth. The results showed that the carrier diffusion lengths have a big effect on how well the HPSC works.

Developing effective device architectures for energy technologies—such as solar cells, rechargeable batteries or fuel cells—does not only depend on the performance of a single material, but on the performance of multiple materials working together. A key part of this is understanding the behaviour at the interfaces between these materials. In the context of a solar cell, efficient charge transport across the interface is a pre-requisite for devices with high conversion efficiencies. There are several methods that can be used to simulate interfaces, each with an in-built set of approximations, limitations and length-scales. These methods range from those that consider only composition (e.g. data-driven approaches) to continuum device models (e.g. drift-diffusion models using the Poisson equation) and ab-initio atomistic models (developed using e.g. density functional theory). Here we present an introduction to interface models at various levels of theory, highlighting the capabilities and limitations of each. In addition, we discuss several of the various physical and chemical processes at a heterojunction interface, highlighting the complex nature of the problem and the challenges it presents for theory and simulation.

Today, the global world is concerned about the rapidly depleting fossil fuel reserves and the serious consequences of these fossil fuels on the environment have prompted an increase in interest in the development of clean and renewable energy sources. Currently, numerous inexhaustible power options, such as solar power, wind power, biomass, etc., are being implemented in the market. However, solar energy is abundant in our environment and is a safe and clean source of energy. As a result, considerable efforts were made in the development of advanced photovoltaic technology to achieve higher power conversion efficiency (PCE) and lower processing costs. In the last 10 years, technological advancements in organic-inorganic halide perovskite solar cells (PSCs) have demonstrated increased absorption coefficient, extended carrier-diffusion length, [1,2] improved carrier mobility, [3,4] ease of fabrication in a variety of areas, and the ability to meet photovoltaic application and space application requirements. [5][6][7] The Pbbased PSC device was initially developed by Kojima et al., who pioneered PSC research and reported a PCE of up to 3.8%. [8] Numerous studies conducted over the last decade have focused on Pb-based PSC devices as a light-absorbing material and have achieved an efficiency of approximately 25.2% in 2019. [9][10][11] The conventional formula of this device structure is ABX 3 which contains an organic methyl ammonium (CH 3 NH 3 þ ) [12] or formamidinium (NH ¼ CHNH 3 þ ) ion [13] and an inorganic element such as Pb, Ge, or Sn. [14,15] Despite its increased efficiency, the problem with this structure is its instability and toxicity, which prevents it from being used commercially. [16] To overcome these difficulties, germanium (Ge) can be used as a perovskite material to provide analogous optoelectronic properties to the PSC. Furthermore, Ge is a far superior contender in terms of stability and environmental friendliness. [17,18] Ge-based PSC devices are more thermally stable in the active layer than lead-based PSC devices, resulting in less material deterioration. [19,20] In the past, different researchers have synthesized Ge-based PSC devices. In 2013, Stoumpos et al., discovered unique nonlinear optical characteristics and a very unconventional structure in the Ge-based perovskite. [21] Following the synthesis of lead-free Ge perovskite materials in 2015, Krishnamoorthy et al. noticed that this class of photovoltaic materials showed a high potential for use in solar panels. [22] Recently, Kanoun et al. and Lakhdar et al. demonstrated computational analysis of the germanium structure of PSC devices, demonstrating an increase in the device's efficacy. [17,23] While researchers have demonstrated an increase in efficiency, the solar cell's current density ( J sc ) is extremely low, and a higher current density is required for the future of Ge-based perovskite solar cells (GBPSCs) with increased efficacy too.The GBPSC is constructed with an absorbance layer of germanium perovskite sandwiched between the ...
