“…This phenomenon is attributed to larger production of e --h + pairs as the thickness increases, with wide spectrum range being absorbed by the layers. The larger production of charges leads to larger recombination as well as collisions leading to formation of series resistance at the interface that leads to decrease in V oc [46,47]. The FF and efficiency continuously increases with thickness, figures 4(c) and (d), as both parameters are partially dependent on V oc and J sc values, as per equations [48],…”

In the realm of photovoltaic applications, scientists and technocrats are striving to maximize the solar cell input photon energy conversion to electricity. However, achieving optimal cell efficiency requires significant time and energy investment for each variation and optimization. To overcome this issue authors simulated and studied the fabricated cell for optimizing conditions, which can save time and efforts for the relatively better outcomes. The family of transition metal chalcogenides holds promise as a material that yield improved outcomes in optoelectronic applications, particularly in photovoltaics. These materials are employed in experimental investigations aimed at enhancing solar cell parameters, resulting in the development of the FTO/ZnO/ZrS2/MoS2/CuO/Au composite cell. Numerical simulations utilizing SCAPS-1D software is conducted, focusing on the significance of CuO as a hole transport layer (HTL), and ZnO as an electron transport layer (ETL). The investigation examines into the impact of various factors, including thickness, bandgap, and carrier densities for both HTL and ETL, on fundamental solar cell parameters. The study indicates that device parameters are influenced by factors such as recombination rate, photogenerated current, charge carrier length, and built-in-voltage. Optimized parameters for HTL, including thickness, bandgap, and carrier concentration, are determined to be 0⋅35 μm, 1⋅2 eV, and 1⋅0 × 1020 cm–3, respectively. For ETL, the optimized parameters are found to be 0⋅05 μm, 3⋅1 eV, and 1⋅0 × 1018 cm–3, respectively. With these optimized parameters, the efficiency of the solar cell reached 20⋅64%, accompanied by open circuit voltage, short circuit current density, and fill factor values of 0.836 V, 36.021 mA⋅cm–2, and 68⋅54%, respectively. The simulated results indicate that addition of two extra layers and the use of efficient binary materials in heterojunction formation can effectively enhance device parameters, offering advantages such as low-cost and large-scale fabrication.

“…Short-circuit current and open-circuit voltage, two important solar cell metrics, can generally rise with an increase in absorber thickness. This rise is explained by the solar cell's increased ability to absorb light from the sun, which produces more charge carriers [68]. Even though a thicker layer facilitates the absorption of a greater number of photons, generating more electron-hole pairs, it concurrently introduces a rise in the density of defects that function as recombination centers.…”

In this study, we have extensively investigated an eco-friendly perovskite-based solar cell via a theoretical approach and numerical simulation. For that purpose, firstly, we have conducted a brief literature review to decipher the current status of Pb-free perovskite solar cells (PSCs). The literature review reflects that the research on Pb-free PSCs is going on with immense interest. By acquiring inspiration from the literature review, we have designed a Pb-free hybrid PSC with a structure of FTO/CdS/FAMASnGeI3/NiO/Ag utilizing SCAPS-1D software. The structure has been optimized by fine-tuning the thickness, and defect density of the light absorbing layer and the thickness, donor density, and band gap of ETL. The optimized structure of Pb-free perovskite material displays promising results with PCE of 30.05 %, Voc of 0.964 V, fill factor of 82.35% and current density of 27.77 mA/cm2. In addition, we have also found that the temperature and light intensity play a crucial role in the performance of the proposed PSC. We have found quantum efficiency as high as 98% for 360 nm thickness of the perovskite absorber layer. Finally, from the dark J–V analysis, lower current density (6.73 × 10−8 mA cm−2), less series resistance (2.8× 10−5 Ωcm2) as well as high shunt resistance (11412.67 Ωcm2) were witnessed, which is expectable for a promising solar cell. Our inclusive exploration unveiled the fact that the suggested novel architecture (FTO/CdS/FAMASnGeI3/NiO/Ag) can be considered an exceptional design for PSCs with greater efficiency and practical suitability.
