“…However, solar cell manufacturers and researchers have not adequately attempted to utilize this powerful tool for modeling advanced solar cells. Numerical simulation in ATLAS-SILVACO is based on the numerical solution of three basic equations of charge transport in semiconductors, including Poisson's equation, the load carrier continuity equation, and the drift diffusion equation for electrons and holes, which are obtained via three types of iterations, including GUMMEL, NEWTON, and BLOCK, respectively [39].…”

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.

“…This is not only because of the wide bandgap of the amorphous-silicon/monocrystallinesilicon HJT structure but also due to the parasitic optical absorption losses in intrinsic and doped a-Si:H layers, especially in the uppermost front-surface field layer. To mitigate the effects of low J sc , the HJ-IBC (HJT interdigitated back contact) architecture has long been known and developed [14][15][16][17] and has attracted significant attention due to the record-high efficiency of 26.7% achieved by Kaneka [18].…”

Crystalline silicon (c-Si) heterojunction (HJT) solar cells are one of the promising technologies for next-generation industrial high-efficiency silicon solar cells, and many efforts in transferring this technology to high-volume manufacturing in the photovoltaic (PV) industry are currently ongoing. Metallization is of vital importance to the PV performance and long-term reliability of HJT solar cells. In this review, we summarize the development status of metallization approaches for high-efficiency HJT solar cells. For conventional screen printing technology, to avoid the degradation of the passivation properties of the amorphous silicon layer, a low-temperature-cured (< 250 ℃) paste and process are needed. This process, in turn, leads to high line/contact resistances and high paste costs. To improve the conductivity of electrodes and reduce the metallization cost, multi-busbar, fine-line printing, and low-temperature-cured silver-coated copper pastes have been developed. In addition, several potential metallization technologies for HJT solar cells, such as the Smart Wire Contacting Technology, pattern transfer printing, inkjet/FlexTrailprinting, and copper electroplating, are discussed in detail. Based on the summary, the potential and challenges of these metallization technologies for HJT solar cells are analyzed.

Bifacial photovoltaic (PV) modules are seen as a promising way to increase the power density and output of solar PV systems. Since a relatively new technology, there is little knowledge on the electrical model of bifacial modules and its dependence on operating conditions. This paper looks into the bifaciality factors of such a module by means of several experimental measurements in controlled environment. It is found that, contrary to the common assumption of constant values, the bifaciality factors in fact vary with the solar irradiance. This irradiance effect is approximated via a linear model and a newly introduced irradiance coefficient. A comparative assessment to the bifaciality factors provided in the datasheet shows that the proposed model more accurately provides these values both at STC and other conditions.
