“…Of the notable features of these inorganic materials, we can mention suitable energy levels compared to perovskites, as well as uniformity, compression, proper electrical properties, abundance, and costeffectiveness, which could greatly reduce the cost of solar cell production. Therefore, in this research, these inorganic materials are used as an alternative to expensive organic hole transporters [30,49]. d.…”

“…Oxygen and moisture in the environment can penetrate through pin-holes and degrade the perovskite absorbent layer; however, the reason for producing pin-holes in HTL is still unclear [29]. To solve this problem, many studies have focused on developing efficient PSCs and new types of hole-transport materials as an alternative to Spiro-OMeTAD [30], or HTL-free PSCs, which are appropriate for simplifying the optimal process of the device, preventing perovskite degradation, and reducing the costs [31].…”

In recent years, perovskite solar cells (PSCs), often referred to as the third generation, have rapidly proliferated. Their most prominent deficiencies are their low efficiency and poor stability. To enhance their productivity, a combination of silicon and perovskite is employed. Here, we present a 3D simulation analysis of various electrical and optical properties of PSCs using the SILVACO simulation software. Using the inverted planar method with inorganic transport materials and the proper selection of anti-reflective coatings with a back contact layer increases the efficiency of PSCs to 28.064%, and enhances their stability without using silicone composites. Several materials, including CaF2, SiO2, and Al2O3, with various thicknesses have been employed to investigate the effect of anti-reflective coatings, and to improve the efficiency of the simulated PSC. The best thickness of the absorbent layer is 500 nm, using a CaF2 anti-reflective coating with an optimal thickness of 110 nm. A polymer composition of Spiro-OMeTAD and inorganic materials Cu2O and NiOx was used as the hole transport material (HTM) and inorganic ZnO was employed as the electron transport material (ETM) to optimize the solar cell efficiency, and an optimized thickness was considered for these materials. Yields of 29.261, 28.064 and 27.325% were obtained for Spiro-OMeTAD/ZnO, Cu2O/ZnO and NiOx/ZnO, respectively. Thus, Spiro-OMeTAD yields the highest efficiency. This material is highly expensive with a complex synthesis and high degradability. We proposed to employ Cu2O to alleviate these problems; however, this reduces the efficiency by 1.197%. As a graphene connector has high flexibility, reduces cell weight, and is cheaper and more accessible compared to other metals, it was regarded as an optimal alternative. The simulation results indicate that using the inverted planar method with inorganic transport materials for graphene-based PSCs is highly promising.

“…For example, CH3NH3PbI3-xClx based inverted PSC with NiO as HTM was simulated using SCAPS and PCE was achieved more than 20 % after optimization [24]. Furthermore, other device simulations of inverted PSCs were also performed with NiO as HTM [25][26][27]. In another device simulation, PSC was investigated with various HTMs including CuI in which only initial simulation was performed without any study of influence of physical parameters on performance of inverted PSC with CuI as HTM [28].…”

Inverted perovskite solar cells (p-i-n PSCs) have been fascinated due to rapid progress of performance in recent years. PEDOT: PSS is commonly used hole transport material (HTM) in p-i-n PSCs which is hygroscopic and acidic in nature that leads towards poor performance of device thus hinders commercialization of PSCs. Therefore, it is necessary to replace PEDOT: PSS with stable HTM in p-i-n PSCs. In this paper, theoretical study is carried out to investigate various physical parameters that can affect the performance of p-i-n PSCs with copper iodide (CuI) as HTM and phenyl-C61-butyric acid methyl ester (PCBM) as ETM. These parameters include the effect of doping density of ETM, absorber, and HTM as well as defect density and thickness of absorber on the performance of p-i-n PSCs. In addition, hole mobility and thickness of HTM is also investigated. It is found that performance of p-i-n PSC is strongly dependent on defect density and thickness of absorber layer while other physical parameters have minor influence on the performance of device. Upon final optimization, device attains PCE of more than 21 % which is encouraging. These results show that CuI as HTM is a potential choice for p-i-n PSCs.

“…The classical 1D drift-diffusion approach is applied to simulate the electrical characteristic of the 2J solar cell using SCAPS-1D program [21]. The limitation of SCAPS-1D program for simulating a tandem junction cell is that, it can't include all the layers (Figure 1) at the same time, as the program can simulate cells with seven layers at best.…”

“…The effect of carrier density (doping concentration) of the absorber layers on the 2J cell's performance is the focal point of this simulation. Both MAPbBr 3 and MAPbI 3 absorber layers are considered self-doped and p-type with holes as majority carriers [21]. The typical carrier densities of the both absorber materials are studied from the referred works [10], [11], [27]- [29] to keep the carrier concentration levels in the simulation within the practically-feasible range.…”

<p>Doping concentration of the absorber layer plays a vital role in the performance of perovskite solar cells, because not only it has a direct impact on the collection efficiency of the photo generated carriers, but it can also be considered as an indicator of the film quality and aging process for so-called self-doped (unintentionally doped) perovskite absorbers, where the carriers are induced from structural imperfections. To observe its influence on the efficiency of perovskite solar cell, a two-junction solar cell structure MAPbBr3/MAPbI3 is analyzed in this study, employing a novel optoelectrical simulation approach with finite-difference time-domain (FDTD) analysis and solar cell capacitance simulation (SCAPS) program. It is found that, the efficiency of the tandem cell falls from ∼22% to ∼12% as front-cell absorber film degrades from single-crystal quality with low self-doped carrier concentration of the order of 1010cm−3 , to degraded film quality with very high carrier concentration of the order of 1018cm−3 . In contrast, the self-doped carrier concentration of the back-cell absorber illustrates less impact on the efficiency of the cell, especially for thicker front-cell absorber. Thus, this case study gives a simpler but novel insight into the long-term stability of the efficiency of high-performance perovskite solar cells establishing a link between the solar cell performance and the self-doped carrier concentration (doping concentration) of the absorber film.</p>
