“…The typical J-V characteristics of (5-AVA) (MA) (1− ) PbI (3− ) Cl PSCs with single-and double-mesoporous layer at different scanning directions with a scan rate of 0.1 V/s are obtained under AM1.5 illumination ( Figure 13). In terms of the scan direction, by comparison, no significant J-V hysteresis is observed in the device with double-mesoporous layer, which may be associated with increasing the thickness of mesoporous layer [29].…”

For the perovskite solar cells (PSCs), the performance of the PSCs has become the focus of the research by improving the quality of the perovskite absorption layer. So far, the performance of the large-area PSCs is lower than that of small-area PSCs. In the paper, the experiments were designed to improve the photovoltaic performance of the large-area PSCs by improved processing technique. Here we investigated the optoelectronic properties of the prototypical CH3NH3PbI3(MAPbI3) further modulated by introducing other extrinsic ions (specifically codoped Cl−and 5-AVA+). Moreover, we used inorganic electron extraction layer to achieve very rapid photogenerated carrier extraction eliminating local structural defects over large areas. Ultimately, we fabricated a best-performing perovskite solar cell based on codoping Cl anion and 5-AVA cation which uses a double layer of mesoporous TiO2and ZrO2as a scaffold infiltrated with perovskite and does not require a hole-conducting layer. The experiment results indicated that an average efficiency of double-mesoporous layer-based devices with codoping Cl anion and 5-AVA cation was obtained with exceeding 50% enhancement, compared to that of pure single-mesoporous layer-based device.

“…To investigate the catalytic performance for photodegradation of methyl orange, the obtained samples were immersed in aqueous methyl orange solution (20 mg/l) fixedly. To achieve linear relationship between concentration and absorbance, the pH of the aqueous solution was adjusted to be 3 [19]. The systems cooled with water jacket were stirred vigorously under dark circumstance with magnetic stirrers for 30 min prior to irradiation so as to achieve adsorption equilibrium of target molecules onto the catalysts.…”

Porous titanium dioxide film is an important photocatalyst. To bridge the gap between the application and traditional preparation of porous TiO2 film, an approach was developed to achieve porous TiO2 film by oxidization. SEM and XRD were used to characterize the morphologies and crystalline structure. Photodegradation of methyl orange was performed to investigate the photovoltaic performance. The results reveal: (i) the film obtained by oxidization has irregular porous structure with many protuberances on its surface, pore diameter ranging from 20 to 300 nm, and an average thickness of 40 μm, while that fabricated by potential anodization was highlyordered with pore diameter of about 50 nm and thickness of about 6 μm; (ii) the former has anatase structure after being calcined, while the latter contains anatase and titanium; and (iii) the former has higher adsorption and photocatalytic activity than the latter.

“…190 Despite the high efficiencies reported in PSCs, there have been concerns over their long term operational stability. Their performance is not only known to degrade over time due to intrinsic reasons such as structural instability and their interaction with the selective transport layers, 192,193 but also, due to extrinsic factors such as moisture, 41,194 This journal is © The Royal Society of Chemistry 2016 UV-light, 39 photon dose, 195 temperature 196 and hysteresis due to light soaking, 197,198 temperature 40 and their slow charge dynamics. 199,200 Flexible PSCs are even more sensitive to these factors as they are more difficult to be encapsulated effectively.…”

a Perovskite solar cells have attracted enormous interest since their discovery only a few years ago because they are able to combine the benefits of high efficiency and remarkable ease of processing over large areas. Whereas most of research has been carried out on glass, perovskite deposition and synthesis is carried out at low temperatures (o150 1C) to convert precursors into its final semiconducting form. Thus, developing the technology on flexible substrates can be considered a suitable and exciting arena both from the manufacturing view point (e.g. web processing, low embodied energy manufacturing) and that of the applications (e.g. flexible, lightweight, portable, easy to integrate over both small, large and curved surfaces). Research has been accelerating on flexible PSCs and has achieved notable milestones including PCEs of 15.6% on laboratory cells, the first modules being manufactured, ultralight cells with record power per gram ratios, and even cells made on fibres.Reviewing the literature, it becomes apparent that more work can be carried out in closing the efficiency gap with glass based counterparts especially at the large-area module level and, in particular, investigating and improving the lifetime of these devices which are built on inherently permeable plastic films. Here we review and provide a perspective on the issues pertaining progress in materials, processes, devices, industrialization and costs of flexible perovskite solar cells. Broader contextFor a number of years, solar cells had been considered as an inferior energy technology due to high cost -even in the renewable energy paradigm; however, more recently progress in materials processing and engineering of highly efficient and stable solar panels have helped them emerge as a frontline renewable energy technology with energy payback time that has been lowered from over a decade to a couple of years (at least in some parts of the world) during the last ten years. Commercial solar panels are typically manufactured on rigid platforms. Fabricating them on flexible substrates, such as transparent plastics and metallic foils, would enable effective harvesting of energy in a number of diverse areas from indoor electronics to automobiles and from building integrated photovoltaics to portable applications. Furthermore, it would open up web-based roll-to-roll fabrication conducive to massive throughputs. Solution processable perovskite solar cells offer promising opportunities towards this end. Being these cells the most efficient among the solution processable ones, with efficiency in their laboratory scale devices on par with the commercially available silicon and thin film counterparts, significant recent efforts devoted to their manufacturing on flexible substrates have seen efficiencies rise as high as 15.6% together with moderate stability. We approach the developments in this area by critically analyzing the factors affecting the final performance indicators such as efficiency, stability, and functionality and relate these to its proces...
