“…[ 57,58 ] To the best of our knowledge, these are the best two Pt-free counter electrodes showing the highest power conversion effi ciency. [ 49,57,58 ] Based on the reports of metal chalcogenide counter electrodes, it is worthy to investigate the electrocatalytic activity of the NiS as a model MS fi lm for DSSC counter electrode prepared by the proposed protocol. In the following, we discuss the complete characterization and the electrocatalytic activities of NiS fi lm towards triiodide reduction in DSSCs.…”

5739wileyonlinelibrary.com deposition method, which is facile, benign, and which can deposit a uniform MS thin fi lms is highly desirable. Although various available techniques such as chemical vapor deposition, [ 9,10 ] atomic layer deposition, [ 11,12 ] molecular beam epitaxy, [ 13,14 ] electrodeposition, [ 7,15 ] successive ionic layer adsorption and reaction, [ 16,17 ] vapor sublimation, [ 18 ] etc., are able to produce thin fi lms of MS, they lack generality or need sophisticated instrumentation, and are complicated. In this context, chemical bath deposition is inarguably the simplest method for thin fi lm deposition. Generally, a suitable complexing agent and pH regulating agents are added in order to avoid spontaneous precipitation in an aqueous bath, which makes the process complicated due to extremely critical optimization for concentration of complexing agents and pH adjustment for an individual MS case. [ 4,[19][20][21][22] As a result, development of MS fi lms by solution-based method has often been a case of trial-and-error with poor reproducibility, which remained as an unexplored research fi eld yet in material science and technology. In order to tackle the above problems in aqueous solution, the fi lm deposition reaction is carried out in ethanol solution without the use of any complexing and/or pH-regulating agents. This protocol relies on dissolution of metal salts and thioacetamide in ethanol and heating the solutions at 70 °C. Although very few reports on MS fi lm deposition from nonaqueous solution has been reported, [ 23,24 ] no general protocol is available that can be applied overall to deposit all variety of MS thin fi lms under similar conditions with good reproducibility. The proposed protocol is extremely simple and general, which can lay simple guidelines to fabricate almost all types of metal sulfi des uniformly over all area of the substrate, provided that the corresponding metal salts are soluble in ethanol. The as-deposited MS fi lms are highly crystalline even without thermal treatment. Interestingly, the fi lms can be directly grown on variety of conducting as well as non-conducting substrates such as glass, plastic, fl uorine doped tin oxide (FTO), Ti-foil, carbon paper, Whatman fi lter paper, etc., which can be of great technological importance. As an example of potential application of these thin fi lms, we demonstrate the use of NiS fi lm deposited on fl exible plastic substrates as FTO-free dual-functioned (electronic support + electrocatalytic) counter electrode in dye-sensitized solar cells Revisiting Metal Sulfi de

A contribution of counter electrode (CE) emphasis a great impact towards enhancement of a dye-sensitized solar cell's (DSSC) performance and Pt based CE sets a significant benchmark in this field. Owing to cost effective noble metal, less abundance and industrial large scale application purpose, an effective replacement for Pt is highly demanded. There are several approaches to improve the performance of a CE for enhancing the power conversion efficiency with a less costly and facile device. To address this issue, reasonable efforts execute to find out suitable replacement of Pt is becoming a challenge by keeping the same electrochemical properties of Pt in a cheaper and eco-friendlier manner. With this, cheaper element based quaternary chalcogenide, Cu2ZnSnS4 (CZTS) becomes a prominent alternative to Pt and used as a successful CE in DSSC also. This review presents brief discussion about the basic properties of CZTS including its synthesis strategy, physicochemical properties and morphology execution and ultimate application as an alternative Pt free CE for a low cost based enhanced DSSC device. It is therefore, imperative for engineering of CZTS material and optimization of the fabrication method for the improvement of DSSC performance.

“…The main disadvantage involves the limited supply of the metal in nature, which is reflected its high cost. Thus, the high cost of the material deposited onto the cathode of a dye-sensitized solar cell can be largely reduced by developing Pt-free alternative electrocatalysts [2,3]. To obtain ideal electrocatalysts for dye-sensitized solar cells, the nanostructured materials are required to possess large surface area, increased surface active sites, and high conductivity.…”
