“…Although only (002) low intensity hexagonal plane were observed at 2θ = 13.20° and 15° without surfactant [49][50][51]. On the other hand, CdS thin films prepared with surfactant and annealed in air with glass protector has the prominent XRD peak at 2θ = 20.5° along (110) plane with cubic structure and other two weak peaks appeared at 15.5° and 23.1° with (002) and (100) planes, respectively with hexagonal structure [34]. It is evident from Fig.…”

“…The CdS solution was spin coated on cleaned substrates at a speed of 2000 rpm for 35 s which is a preferential speed for the uniform and smooth film deposition [34]. Then the deposited CdS thin films were dried at 90 °C for 15 min on a hot-plate to take away the residual solvents.…”

“…Finally, the CdS thin films were annealed in a low vacuum chamber (0.07 Torr) at 300 °C for 5 min for the crystallization of the films and to avoid oxidation. This annealing temperature was chosen as it offered comparatively better surface morphology, crystallinity as well as the optical properties than others films annealed below and above 300 °C using simple open-air glass protector annealing system [34]. The entire process of CdS thin films deposition is shown in Fig.…”

“…The crystallite sizes of CdS thin films were calculated from XRD data using Scherrer's equation [34]. The crystallite sizes for planes (002), (002) and (100) were found to be about 17.12, 15.80 and 11.50 nm, respectively for TX-100 assisted CdS film where the determined crystallite sizes surfactant free film at planes (002) and (002) were about 12.20 and 14.34 nm, respectively.…”

“…Other than CBD, extensive diverse methods have been reported to deposit CdS thin-films including electrodeposition [24], spray pyrolysis [25], pulsed DC magnetron sputtering [26], molecular beam epitaxy (MBE) [27], chemical vapor deposition (CVD) [28], successive ionic layer absorption and reaction (SILAR) [29,30], electron beam evaporation [31], pH-controlled growth solutions [32], spin coating [33] etc. Most recently, we have reported the direct solutionprocessed thiol-amine cosolvents assisted synthesis of air annealed CdS thin films using glass protector where Triton X-100 surfactant has been used for the uniform deposition of the films [34]. There are also few reports of the use of nonionic surfactants aided synthesis of CdS films [18,35,36].…”

In this article, the effect of Triton X-100 surfactant on the spin coated and vacuum annealed CdS thin films on glass substrates using thiol-amine cosolvents have been explored in details. The SEM study reveals that the surfactant assisted CdS films are uniform, homogeneous and smooth having less cracks, voids, pinholes compared to CdS films synthesized without surfactant. The X-ray diffraction spectra indicate the hexagonal structure of the surfactant-added films with (002) and (100) planes having relatively high intensity whereas a weak hexagonal (002) peak appears for the films deposited without surfactant. Two prominent Raman peaks of CdS thin films are observed at the wavenumber 207 and 212 cm −1 due to the multi-phonon vibration of hexagonal CdS. A relatively strong and broad FTIR peaks at 1647 and 670 cm −1 were observed due to the Cd-S bending and stretching vibration in the surfactant mediated films. Surfactant induced CdS films are nearly stoichiometric as manifested by the energy dispersive X-ray report. Finally, higher optical transmission and band gap have been achieved for the CdS thin films deposited with Triton X-100 surfactant. This study reveals that surfactant mediated CdS thin films with thiol-amine cosolvents can be exploited effectively in higher efficiency thin film solar cell technologies with low cost.* Jaker Hossain, jak_apee@ru.ac.bd; * Abu Bakar Md.

Herein, the role of bulk/interface defects and their impact on the performance of novel solar cell device structure p‐Si/n‐CdS/ALD‐ZnO (atomic layer deposited zinc oxide) heterojunction solar cells are shown. To calculate all important parameters and connect both types of defects with the performance of the solar cell, a theoretical model to simulate using well developed, established, and globally popular SCAPS‐1D simulation tool is developed. The different types of optimized simulation parameters that improved the performance of the solar cell have been calculated using bulk defects (p‐Si absorber), interfacial defects (p‐Si/n‐CdS interface), emitter layer (n‐CdS) thickness, and window layer (ALD‐ZnO) thickness. A further effect of incident radiation on the quantum efficiency and the spectral response has been plotted along with the I–V characteristics of the proposed solar cell. Based on the proposed simulation and comparing with the existing experimental and simulation results for similar combinations of the solar cell, this detailed study suggests that the highest efficiency η = 19.97%, fill factor = 83.37% with open circuit voltage = 635.3 mV, and short circuit current = 37.71 mA cm−2 can be achieved. Finally, the obtained performance parameters are best in class with the tabulated existing ones.

CdTe‐based thin film solar cell has been modeled and enumerated with a thin CuInTe2 (CIT) current booster layer. CdTe‐based n‐CdS/p‐CdTe/p+‐CIT/p++‐WSe2 heterojunction device is evaluated for the highest performance. It is revealed that physical parameters such as thickness, doping, and defects of the CIT layer have a significant influence on the performance of the CdTe solar cell. The device shows an efficiency of 37.46% with an open‐circuit voltage, VOC, of 1.102 V, short‐circuit current density, JSC, of 38.50 mA cm−2, and fill factor, FF, of 88.30%. The use of the photon recycling technique with a Bragg reflector with 98% back and 95% front reflectance only provides an efficiency of ≈44.3% with a current of 45.4 mA cm−2. These findings are very hopeful for the production of efficient CdTe solar cells in the near future.
