Nanocrystalline cadmium sulfoselenide thin films have been synthesized using a self-organized arrested precipitation technique with different deposition times using triethanolamine as a complexing agent. Optical, structural, morphological and photoelectrochemical solar cell properties were investigated as a function of deposition time. A UV-Vis-NIR absorption study suggested a direct allowed transition type and the band gap energy decreased from 2.01 to 1.86 eV with the increase in deposition time. X-ray diffraction studies revealed that the thin films are nanocrystalline by nature with a pure hexagonal crystal structure and a calculated crystallite size of 51-68 nm. Field emission scanning electron microscopy demonstrated that the surface morphology was altered from nanoflakes to assorted nanoflakes-nanospheres and finally to a nanocoral-like morphology. X-ray photoelectron spectroscopy and energy dispersive X-ray spectroscopy showed that the composition of the Cd(SSe) thin films was of good stoichiometry. Electrical conductivity and thermoelectric power measurements confirmed that the deposited films were n-type semiconductors. From J-V measurements, a highest photo-conversion efficiency of 0.57% was achieved.The significant boost in the PEC performance might be due to the improved crystallinity along with lower values of the grain boundary resistance, dislocation density and the microstrain of the Cd(SSe) thin films.

“…It is important to note that the observed 3-D columnar structure exhibits qualitative similarities to that found in a single perovskite layer annealed above 140°C . 25 However, annealing at the lower temperature of 120°C, as employed in the MAPI-based solar cell structure of this study, did not show evidence of thermal decomposition. This suggests that the decomposition of MAPbI 3 in the solution-processed solar cell structure is likely influenced by the solvent used during the PC 70 BM film deposition process (section 2.2).…”

“…These columns were previously identified as PbI 2 crystals and are visualized through the local increase in the yield of methylammonium cluster ions, attributable to the matrix effect . 24,25 In our previous works 24,25 and other report in literature , 38 the formation of columnar structures was attributed to the heating of perovskite during thermal annealing process. During this process, the perovskite undergoes degradation, leading to the formation of a new phase (PbI 2 ) in the form of crystallites that penetrate throughout the entire perovskite layer.…”

“…[21][22][23] Additionally, TOF-SIMS enables the investigation of the degradation processes occurring at these interfaces under different conditions, shedding light on the mechanisms that may impact the long-term stability and performance of perovskite solar cells. 24,25 In this study, we conduct a detailed examination of the interfaces within the device structure using the TOF-SIMS technique. Additionally, we utilize scanning electron microscopy (SEM) to study the surface structure of the interfaces, complementing our understanding of their morphology and characteristics.…”

This study focuses on investigating interfaces in perovskite solar cells (PSCs) fabricated by using two different deposition methods. One structure involves all-solution processing, with the photoactive layer spin-coated, and organic semiconductors for the hole and electron transporting layers (HTL and ETL). The other structure incorporates inorganic HTL and ETL layers deposited via magnetron sputtering. We analyze the interfaces using TOF-SIMS and SEM, comparing the two manufacturing approaches to understand their impact on interface quality. Additionally, we explore how different humidity levels during fabrication influence solar cell performance. This research aims to advance the understanding of the correlation between interface quality and the performance of perovskite solar cells.
