“…Nevertheless, finer structure is in fact evident within the large domains (Figure 21, panels C and D), as confirmed by several other groups. 261,262 It is most probable that they are composed of "sub-grains" with much smaller size than the apparent domain size. This discrepancy may be explained by noting that the "hot-casting" approach does not take place under conditions remotely approximating thermal equilibrium.…”

Halide perovskites are an intriguing class of materials that have recently attracted considerable attention for use as the active layer in thin film optoelectronic devices, including thin-film transistors, light-emitting devices, and solar cells. The "soft" nature of these materials, as characterized by their low formation energy and Young's modulus, and high thermal expansion coefficients, not only enables thin films to be fabricated via low-temperature deposition methods but also presents rich opportunities for manipulating film formation. This comprehensive review explores how the unique chemistry of these materials can be exploited to tailor film growth processes and highlights the connections between processing methods and the resulting film characteristics. The discussion focuses principally on methylammonium lead iodide (CH 3 NH 3 PbI 3 or MAPbI 3 ), which serves as a useful and well-studied model system for examining the unique attributes of halide perovskites, but various other important members of this family are also considered. The resulting film properties are discussed in the context of the characteristics necessary for achieving high-performance optoelectronic devices and accurate measurement of physical properties.

“…3,4 Current progress in perovskite solar cells largely benefits from the advance of solution methods in promoting the microstructure and morphology. [5][6][7] A one-step spin-coating method was firstly employed to prepare MAPbI 3 perovskite solar cells, showing an initial efficiency of 3.8% due to the dendritic morphology with poor coverage. 8 Subsequently, a modified one-step method involving the use of antisolvents was proposed to improve the film morphology by promoting the crystallization process.…”

“…As an emerging photovoltaic material, organolead halide perovskites in PSCs have demonstrated many superiorities over the traditional ones, e.g., tunable band-gap, ultralong carrier diffusion length, as well as good solution processibility that is highly desired for future cost-effective and facile fabrication [1][2][3][4]. PSCs exhibit high flexibility in cell architectures and the ones that contain mesoporous scaffolds are usually classified to be mesoscopic PSCs (M-PSCs) which are extraordinarily representative and reliable in terms of achieving high photoelectric conversion efficiencies (PCEs) [5,6].…”

Rational design of SnO2-based electron transport layer in mesoscopic perovskite solar cells: more kinetically favorable than traditional double-layer architecture

et al. 2017

Here, the interfacial synergism of discontinuous spot shaped SnO 2 and TiO 2 mesoporous nanocomposite as electron transfer layer (ETL) underlayer is presented in highly efficient mesoscopic perovskite solar cells (M-PSCs). Based on this new strategy, strong charge recombination observed in previous SnO 2 -based ETLs is suppressed to a great extent as the pathways of charge recombination and energy loss are blocked effectively. Meanwhile, the internal series resistance of entire M-PSC is decreased remarkably. The new ETL is more kinetically favorable to electron transfer and thus results in significant photovoltaic improvement and alleviated hysteresis effect of M-PSCs.
