“…This result may be related to the fact that the pores become larger as the TiO 2 particle size increases, as shown in the pore size distribution (Figure 2b). The larger perovskite crystals can be formed in the larger pores, resulting in fewer defects on the perovskite crystal and a reduction in non-radiative recombination [31,32]. In Figure 5d, there was no clear correlation between FF for all solar cells.…”

Fully printable carbon-based multiporous-layered-electrode perovskite solar cells (MPLE-PSCs) are easy to fabricate and have excellent durability. In this study, the porosity of the mesoporous TiO2 layer as the electron transport layer in MPLE-PSCs was controlled by varying the particle diameter of TiO2 nanoparticles from 14 nm to 98 nm. Furthermore, the results of absorbed photon-to-current conversion efficiency, visible light reflectance spectroscopy, pore-size distribution, X-ray diffraction, field emission scanning electron microscopy, and photovoltaic parameters of MPLE-PSCs are discussed. Although the porous TiO2 layer with smaller nanoparticles showed higher photoabsorption, it was found that the more voids of perovskite crystals created in the TiO2 porous layer, the smaller the particle size (<18 nm). The porous TiO2 layers with particles over 26 nm are well filled with perovskite crystals, resulting in a higher photovoltaic capacity with TiO2 particles over 26 nm. As a result, the short-circuit current density (JSC) showed a maximum value using 43 nm TiO2 particles, with an average power conversion efficiency (PCE) of 10.56 ± 1.42%. Moreover, the PCE showed a maximum value of 12.20% by using 26 nm TiO2 nanoparticles.

“…More importantly, this ink is environmentally friendly and constitutes an excellent protective layer for perovskites, accounting for its chemical inertia and water resistance, hence improving PSC device stability. [ 194–197 ] Indeed, early in 2014, Yang and co‐workers [ 63 ] developed a metal‐free electrode based on inkjet‐printed carbon‐based ink, to effectively fabricate an efficient PSC device. The used printing technique allowed precise control of the patterned carbon electrode and further improved the interface between the perovskite absorber and carbon electrode through an instant chemical reaction.…”

The demand for cost‐effective and rapid processing of large‐area thin films in the photovoltaic industry has recently driven significant research interest. In this context, among the various approaches explored, printing devices, particularly perovskite solar cells (PSCs), have garnered considerable attention due to their potential for scalability and cost efficiency. Besides, solution printing is widely recognized as an appealing strategy for large‐area, cost‐effective, and high‐throughput production of PSCs. However, while substantial progress has been made in this process, challenges related to stability, uniformity, and scalability remain to be addressed. This review critically examines the key printing techniques and substrates employed in PSC fabrication. Then, given the significance of ambient air printing for industrial applications, fundamental challenges associated with achieving ambient air production of PSCs are discussed in detail. Moreover, the formulation strategies of perovskite ink in printing technologies are thoroughly explored, considering its crucial role in determining the performance and stability of printed PSCs. Finally, the printing process for various components of PSCs, including the perovskite absorber layer, charge transport layers (CTLs), and electrodes, is meticulously analyzed, highlighting current achievements and remaining hurdles.

Nanotechnology has advanced the techniques for elucidating phenomena at the atomic, molecular, and nano-level. As a post nanotechnology concept, nanoarchitectonics has emerged to create functional materials from unit structures. Consider the material function when nanoarchitectonics enables the design of materials whose internal structure is controlled at the nanometer level. Material function is determined by two elements. These are the functional unit that forms the core of the function and the environment (matrix) that surrounds it. This review paper discusses the nanoarchitectonics of confined space, which is a field for controlling functional materials and molecular machines. The first few sections introduce some of the various dynamic functions in confined spaces, considering molecular space, materials space, and biospace. In the latter two sections, examples of research on the behavior of molecular machines, such as molecular motors, in confined spaces are discussed. In particular, surface space and internal nanospace are taken up as typical examples of confined space. What these examples show is that not only the central functional unit, but also the surrounding spatial configuration is necessary for higher functional expression. Nanoarchitectonics will play important roles in the architecture of such a total system.
