“…Exposure to extreme heat, light, oxygen, and humidity aggravates interface flaws, further impairing device performance. So, it's impossible to completely rule out the possibility of interface flaws 39 , 40 . Thus, to study the impact of CZTS/ZnS and CZTS/Cu 2 O interface defects, the defect density was varied from 10 10 to 10 16 cm −2 .…”

Copper Zinc Tin Sulphide (CZTS) is a propitious semiconductor for active absorber material in thin-film solar cells (SCs). Here, SC architecture comprising FTO/ZnS/CZTS/variable HTLs/Au is discussed. Fluorine-doped tin oxide (FTO) and gold (Au) are used as front and back contacts, respectively. Zinc sulphide (ZnS) is used as an active electron transport layer (ETL), while different Cu-based materials (Cu2O, CuO, CuI, and CuSCN) are used as hole transport layers (HTL). A one-dimensional solar cell capacitance simulator (SCAPS-1D) is utilized to simulate the SC structure. Among different Cu-based HTLs, Cu2O is preferred as a potential candidate for high cell performance of CZTS-based SC. The effects of various layer parameters such as thickness, doping density, and carrier concentrations, electron affinity of HTL and absorber, respectively, are also discussed. After optimization of the device, variation of operating temperature and the effect of series and shunt resistance are also taken into consideration. The optimized results of thickness and acceptor concentration (NA) of absorber material are 1.5 µm and approx. 1.0 × 1019 cm−3, respectively. In addition, the function of HTL (with and without) in the designed SC structure is also studied. Capacitance–voltage (C–V) characteristics are also discussed to get an insight of built-in potential. We have achieved cell performances viz. efficiency = 31.86%, short circuit current density = 32.05 mA/cm2, open circuit voltage = 1.19 V, and fill factor = 83.37%.

“…For both incoming light and photo-generated electrons, IL 1 serves as a window. If IL 1 has a high defect density, this will result in electron-hole pairing before separation, which will reduce PCE [64]. Along with this, defects also alter the dynamics of ion recombination and migration.…”

It is usually anticipated that perovskites will be an appealing material for extremely effective solar cells. However, its practical applications are constrained by its hazardous properties and stability. Thus, CsSn0.5Ge0.5I3, a more environmentally benign substitute for toxic lead-based perovskites, provides superior stability in solar cells. This work reports on the numerical modeling and computational analysis of a heterostructure CsSn0.5Ge0.5I3, With TiO2 and D-PBTTT-14 serving as the electron and hole transport layers, respectively. The introduction of D-PBTTT-14 as an hole transport layer was motivated by its superior stability over existing organic HTLs. Furthermore, higher generation rate and very favorable absorption coefficients of each layers manifested improved efficiency. Various parameters were examined in order to enhance the newly designed solar cell performance such as: thickness, defect density, doping density, Coefficient of radiative recombination, defect at interface, shunt and series resistance, front and back contacts, and operating temperature. Perovskite solar cells with their current architecture have the potential to achieve a current density (Jsc) of 28.31 mA/cm2, an open-circuit voltage (Voc) of 1.24 V, a fill factor (FF) of 85.90%, and efficiency of 30.27%.

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.
