“…On the other hand, although TMCs in DSSCs present superior catalytic performances, the possibility of implementing these CE materials in practical applications will be greatly discounted without thorough stability tests.

Biomass resources have attracted considerable attention due to their renewability and cleanliness. Anaerobic fermentation (AF) is a preferred technology to effectively utilize the biomass resources. To improve AF environments, the addition of accelerants in AF is an effective technical strategy. Nano-structured transition metal compounds (TMCs), due to their distinctive structure and unique properties, have been widely applied in different catalytic fields, such as solar cells, fuel cells, capacitor, biosensors, hydrogen generation, energy storage, organic matter decomposition, and pollution control. In this regard, we investigated the effects of TMCs used as counter electrode (CE) catalysts on the performance of dye-sensitized solar cells (DSSCs), and the role of TMCs as accelerants on the environment of the AF. These TMCs exhibited remarkably superior performance as alternative Pt-free CEs in DSSCs and as accelerants in AF. Research in this direction is expected to open new avenues for the use of TMCs in upcoming energy fields such as biomass energy and solar energy.

“…Conventional DSSCs were constructed with liquid -state electrolytes and they have reached to PCE of 13 % with cobalt-based redox shuttle and an engineered donor--acceptor dyes [25]. One of the challenges DSSCs have is improvement of their long -term stability which showed in degradation of photoanode and counter electrode, concentration drop in electrolyte redox couple, and encapsulation related issues [26]. The liquid electrolyte of DSSCs could be replaced with 2,2',7,7' -tetrakis (N,Ndimethoxyphenylamine)-9,9'-spirobifluorene (spiro -OMeTAD) (solid state hole transport material (HTM)) to minimize stability issues [28].…”

A B S T R A C TSolar energy has the potential to solve world energy problem as it is pollution-free. It could be enhanced using perovskite material as absorber in perovskite solar cells. The history and what this material is made up of are emphasized. Different methods of fabrication, improving the power conversion efficiency (PCE) and factors influencing degradation of perovskite based solar are stated. Because of the fact that this material based solar cells are not yet developed, its stability was reviewed to bring different technology employed in tackling the stability aiming for a better understanding of the material and the devices, and facilitates the commercialization of perovskite solar cell.

“…One important case is the segmented cell method [2,45,46,47], which is a new in-situ technique for aging studies. A typical question related to segmented cells is how quickly the neighbouring segments aect each other, and for this purpose both 2D and transient modeling features are required.…”

A two-dimensional transient model of dye solar cells (DSC) describing the electrochemical reactions in the cell has been prepared. The model includes the relevant components of DSCs: the photoelectrode, the electrolyte, and the counter electrode. The solved variables are potential and the concentrations of the dierent ion species, which can be used to determine e.g. the current-voltage characteristics of the cell. The largest benet of this model is its 2D features which enable the study of lateral inhomogeneity. Using the model, a new phenomenon was described: lateral current density distribution caused by a small dierence in the size between photoelectrode and counter electrode, typical to laboratory test cells, causes tri-iodide to move from the edge region to the active area of the cell. This process takes relatively long time (8 min) and can be important for performance characterization and design of DSCs.
