“…The evolution of the dark J-V curves can be used to evaluate the preliminary electrochemical stability of CE materials, which can further provide insight into the changes that occur during aging. 74,82,83,146,[148][149][150][151][152] The dark J-V curves clearly indicated whether the onset of the dark current of the DSSCs with different CEs is considerably close to that of the DSSC with the Pt electrode, and whether the dark current of the DSSCs with different CEs show abnormal differences. Through these phenomena, we can finally judge whether these developed CE materials can react with the redox couple electrolyte.…”

Platinum (Pt)-free counter electrodes (CEs) are economical alternative components of dye-sensitized solar cells (DSSCs) that have attracted much interest and become the focus of research, with an increasingly large number of scientific papers published in the last two decades. The development of these CE materials was driven mainly by desires to overcome the disadvantages of Pt, as follows: high cost, scarcity, corrosion by the I3\u7f/I\u7f redox couple electrolyte, and mismatch or non-effectivity in the I-free redox couple electrolyte. Although much more is now known about the principal physicochemical processes that occur during CE operation of the DSSC, the stability issues associated with CEs have not been matched by the exponential increase in CE research effort. This raises questions regarding the stability of the CEs whether the present research is sufficiently addressing the stability issues that limit DSSC performance. This review attempts to identify some of the key techniques that evaluate CE stability in DSSCs through a selective presentation of recent research highlights. Classical approaches could effectively assess the probability of using alternative Pt-free CE materials for commercial application, which offer strategies to overcome the current stability stalemate

Over the past decades, chemical bath deposition (CBD) has proven its suitability and has established itself as one of the prominent techniques for depositing different metal chalcogenide semiconductor thin films via ion-byion or by adsorption of colloidal particles from the chemical bath on the substrate. It is a simple, cost-effective and convenient method for large-scale deposition and has recently received a surge of interest. This article reviews the research progress in various methods or techniques including CBD for the preparation and study of the properties of metal chalcogenides. Various parameters for efficient preparation and variation in structural, morphological, compositional, optical properties, etc. are also briefly discussed.

“…Besides, the catalyst should retain its activity for a longer period. There are several factors which influence catalyst activity like active phase loading and oxidation state as well as surface area of the catalyst, promoters and dispersion of active compound [20,21].…”
