Transition metal sulfides (TMSs) are of special interest in energy conversion and storage devices. Amongst all sulfides, fool's gold or iron pyrite (FeS 2 ) is potentially an attractive candidate for photovoltaic applications. Iron pyrite has risen to prominence due to its distinct properties and abundance in nature to meet the large scale needs. It is considered as environmentally benign solar absorber material with high absorption coefficient, α > 6 x10 5 cm À 1 for λ � 700 nm and suitable energy bandgap (E g = 0.95 eV). Numerous physical and chemical methods have been employed to deposit nanocrystalline pyrite thin films directly from source materials or indirectly by sulfuration. This review gives an overview of pyrite as a low cost photovoltaic absorber material for contemporary solar cell structures. In addition, practical approaches like the rational design of nanocomposites, band gap engineering and nanostructure synthesis of pyrite for improving its properties particularly photovoltaic properties are also deliberated. Moreover, limitations, challenges, remedies and prospects of pyrite as potential photovoltaic material are also reviewed to further advance the development of pyrite-based solar cell configurations.[a] Dr.at a low precursor concentration, pyrite nanocubes (125-250 nm in 20-180 min) were obtained due to low nuclei concentration and slow growth (diffusion limited) in quasiequilibrium.

“…After 2 hours, the mixture became completely transparent and viscous. This signified that the transparent electrolyte gel was formed [17], [18], and ready to be poured to the semipermeable membrane container layer. This new generation of three-layer electrochromic devices contains an electrochromic displaying electrode (PEDOT:PSS coated polyester fabric), a semipermeable membrane (Tissue paper) representing the electrolyte container and a counter electrode (Aluminum sheet).…”

The textile-based electrochromic (EC) display which has been developed and presented in this article, is very compact, robust, flexible, stable, efficient, economical, and inclined to biocompatibility. The developed textile display is having only three-layer over conventional seven layers patented electrochromic structures. It is also very efficient, as it can perform its functionality even after 2500 cycles of a run and 1500 times of bending. The innovative and simplified structure of the EC device has been developed with only 3 layers, including the displaying electrode, the electrolyte container, and the counter electrode. The conductive polymer PEDOT:PSS used here as a conductive and electrochromic material, is coated on the textile substrate to perform as one side of the electrode for the asymmetric arrangement of the electrochromic device. The experiment has also been done to find out the best possible textile fabric to serve as the optimal electrochromic container. The biocompatible H3PO4 gel drenched in the semi-permeable membrane has been used as an ion transfer medium for the electrochromic display. This biocompatible ion transfer medium is sandwiched in between the electrochromic displaying electrode (PEDOT:PSS coated on fabric) and aluminum sheet (counter electrode) for making this handmade crude electrochromic display. The investigation of the EC display functioning has been observed through cyclic voltammetry within the life cycle run. The performance of the device has also been investigated in real-life conditions, by providing just ±2.0 V DC power. The other possibility is shown in our article to deposit the PEDOT:PSS compound on the textile substrate was to coat directly the yarns and then to use them into the weaving process to produce the displaying electrode. By this technique, it would also be possible to develop hybrid displays made of structures containing knitted or woven side-emitting optical fibers and our electrochromic display structure, locally.

“…The method consisted of two steps, wherein the first step consisted of the preparation of polysulfide solution, and then, iron precursor was added to initiate a nucleophilic reaction at 100 °C in an inert atmosphere. The final product had a pseudo-octahedral structure showed in Figure . The group used a similar strategy, this time using trisodium citrate as a capping agent to prevent particle agglomeration .…”

With an increase in energy demand and the depletion of conventional fuels, solar cells are emerging as an excellent alternative, providing a sustainable and clean source. Solar cells consisting of different materials have been introduced in recent years, and the overall performance defined by these materials has a lot of potential to increase. Transition metal dichalcogenides have gained significant importance due to their advantageous properties and promising potential. Iron disulfide or pyrite is one such material that has risen as a favorable material for photovoltaics cells owing to its suitable band gap, high absorption coefficient, and low cost. Not only this, the “earth abundance” and nontoxicity have also increased its prospects as a photovoltaic material. This study aims to review recent progress on the synthesis of pyrite and its utilization in photovoltaics. Different methods used for the synthesis of pyrite are reviewed followed by the properties of pyrite, the challenges that hinder its efficiency, and the possibilities of further research in this area.
