“…The results depict that all solar cells’ V OC and FF enhanced with increasing ZrS 2 thickness due to the reduction in recombination rate at the absorber/buffer interface and decrement in the Rs of the solar cells, respectively. [ 54 ] On the other hand, it can be seen that J SC slightly decreased for SnS, Cu 2 SnS 3 , and CuSb(S,Se) 2 solar cells. This behavior can occur due to the slight reduction in the generation of charge carriers in the absorber, resulting from small light absorption in ZrS 2 .…”

SnS, Sb2Se3, Cu2SnS3, CuSb(S,Se)2, and Cu2BaSn(S,Se)4 are emerging as promising light absorbers for thin‐film photovoltaics due to their extraordinary optoelectronic properties. However, improper band alignment with the buffer and large open‐circuit voltage (VOC) deficit limits their power conversion efficiencies (PCE). Therefore, finding a suitable buffer that overcomes these obstacles is crucial. Herein, ZrS2 as an alternative buffer for the aforementioned emerging thin‐film solar cells using SCAPS‐1D is proposed. The important ZrS2 parameters are optimized, including bandgap, thickness, carrier concentration, and defect density. Interestingly, ZrS2 behaves as a degenerate semiconductor at carrier concentrations >1E17 cm−3, improving the conductivity of the solar cells; it also demonstrates a high defect tolerance nature when the defect density lies between 1E12 and 1E18 cm−3. After ZrS2 parameters optimization, the built‐in potential of SnS, Sb2Se3, Cu2SnS3, CuSb(S,Se)2, and Cu2BaSn(S,Se)4 solar cells is enhanced by 0.2, 0.58, 0.05, 0.42, and 0.3 V, respectively, reducing recombination rate. Upon optimizing absorbers parameters, a PCE > 35% for SnS, Sb2Se3, and CuSb(S,Se)2 while >32% for Cu2SnS3 and Cu2BaSn(S,Se)4 solar cells is accomplished with low VOC loss (≈0.1 V). The absorbers must have high carrier concentration (1E20 cm−3) and low defect density (1E14 cm−3) to achieve these PCEs.

In this research work, a copper bismuth oxide- (CuBi2O4-) based thin-film solar cell has been proposed for the lead and toxic-free (Al/ITO/TiO2/CuBi2O4/Mo) structure simulated in SCAPS-1D software. The main aim of this work to make an ecofriendly and highly efficient thin-film solar cell. The absorber layer CuBi2O4, buffer layer TiO2, and the electron transport layer (ETL) ITO have been used in this simulation. The performance of the suggested photovoltaic devices was quantitatively evaluated using variations in thickness such as absorber, buffer, defect density, operating temperature, back contact work function, series, shunt resistances, acceptor density, and donor density. The absorber layer thickness is fixed at 2.0 μm, the buffer layer at 0.05 μm, and the electron transport layer at 0.23 μm, respectively. The CuBi2O4 absorber layer produces a solar cell efficiency of 31.21%, an open-circuit voltage ( V oc ) of 1.36 V, short-circuit current density ( J sc ) of 25.81 mA/cm2, and a fill factor (FF) of 88.77%, respectively. It is recommended that the proposed CuBi2O4-based structure can be used as a potential for thin-film solar cells that are both inexpensive and highly efficient.

“…FTO and Au have work functions of 4.4 eV and 5.1 eV, respectively. We used the following settings for all defect layers: At 300K, the thermal velocity of electrons and holes is 10 7 cm/s, the energy distribution is Gaussian, the characteristic energy is 0.1 eV, and the energy level relative to the reference is 0.6 eV [18]. We provided absorber/ETL and absorber/HTL interface defects with hole capture cross section of 10 -18 cm 2 and 10 -19 cm 2 , electron-capture cross section of 10 -19 cm 2 and 10 -18 cm 2 respectively, and interface defect density of 10 13 cm -3 .…”

Because of the toxicity and stability concerns, commercialization of lead-based perovskite solar cells (PSCs) is limited. Solar cells made entirely of Ti-based all-inorganic perovskite could be a viable answer to these issues. This paper is a theoretical paper on a perovskite solar cell (PSC) based on Cs2TiI6 using all-inorganic charge transport materials. We proposed a high performance perovskite solar cell (PSC) according to variables such as charge transport materials and its optimal thicknesses, absorber thickness, absorber defect density and interface defect density and working temperature. The optimal absorber thickness, Hole transport layer (HTL) thickness, and Electron transport layer (ETL) thickness are 500 nm, 50 nm, and 10 nm, respectively. After analyzing the other factors, we ended up with a high-performance PSC with a power conversion efficiency of 22.5% at room temperature and 22.84% at 270 K. These results are useful for the conception and manufacture of PSCs.
