“…This enhancement in the crystallite size with the minimum interfacial energy is beneficial for improving the photon conversion efficiency. 38,39 From the calculated crystallite sizes (D), dislocation densities (d) and microstrains (e) for all samples were determined using eqn ( 9) and (10) and the data are summarized in Table 2.…”

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.

“…Also, it is not only a simple and inexpensive method but a promising way to produce single crystals with less structural imperfection [16]. To date, many electrochemical processes for the synthesis of CdSe thin films have been carried out in aqueous, non-aqueous, acidic, and alkaline baths [17][18][19][20][21][22][23][24]. Apart from previous studies, here we have developed a ED method by which the CdSe thin films can be grown from primarily amorphous grains to self-assembled nanowires in template-and surfactant-free conditions.…”
