first solid-state perovskite solar cell (PSC) was successfully prepared by introducing Sprio as a hole transport layer (HTL), tremendous efforts have been devoted to further promoting the photovoltaic performance, including surface passivation, bulk doping, processing engineering, and optimizing the structure of the device. [9][10][11][12][13][14][15][16][17][18][19][20][21] Consequently, the power conversion efficiency (PCE) of PSCs has dramatically increased from the initial 9% to an impressive 25.2% in several years. [22,23] To date, the coexistence of high efficiency and long-term stability has become a crucial requirement for successful PSC applications. 2D perovskites (consisting of pure 2D and quasi-2D perovskites) have emerged as a new family of photovoltaic materials that have been proven to resolve the problem of instability in perovskites. Owing to the insulating spacer layer, inherent outstanding long-term stability is obtained in 2D perovskites, including hydrophobicity, suppression of ion migration, and larger formation energy. [24][25][26][27][28] However, severe carrier recombination occurs due to the combined effect of quantum confinement and dielectric confinement, rooted in the natural multiple quantum wells structure (MQWs) (Figure 1), where the inorganic parts act as potential "wells" while the organic parts act as "walls", which shows a boost in the photovoltaic performance of 2D PSCs. [29][30][31] To realize the coexistence of high efficiency and ultrastability in PSCs, researchers began to construct 2D/3D heterostructures by surface passivation. [32][33][34][35][36][37][38][39][40] In fact, before the boosting of the 2D/3D stacking concept, many researchers have applied large ammonium cations (such as phenethylamine (PEA), butylamine (BA), and quaternary ammonium (QA)) as defect passivants to 3D perovskite solar cells. [41][42][43][44][45] During this period, the pure PEA-or BA-based 2D perovskites have been explored as light-absorbing materials for better stability. [25,46] In 2015, Yao et al. introduced in situ grown 2D perovskite (PEI) 2 PbI 4 (PEI: polymeric ammonium) on an MAPbI 3 film, leading to more stable and efficient PSCs. [47] In 2016, discussions and analyses of the surface passivation effect began to emerge, which involved exploring a series of 2D perovskite molecules (such as aniline, benzylamine, and PEA). [42,45,48] The concept of 2D/3D stacking really stood out in 2018 by unveiling the chemical reaction mechanism for heterojunction formation and the mechanism for enhancing stability. For example, Huang 3D perovskite solar cells (PSCs) have shown great promise for use in next-generation photovoltaic devices. However, some challenges need to be addressed before their commercial production, such as enormous defects formed on the surface, which result in severe SRH recombination, and inadequate material interplay between the composition, leading to thermal-, moisture-, and light-induced degradation. 2D perovskites, in which the organic layer functions as a protective barrier ...

“…[22,73] Among the emerging technologies, perovskites gained huge attention because of their tunable bandgap (by engineering the chemical composition), high and panchromatic α allowing thin samples (≈500 nm) to absorb the whole solar spectrum, low cost and fabrication from liquid solutions. [30,[74][75][76] As a result, currently labscale perovskite-based SCs show PCE = 25.5%. [22] However, such devices still suffer from stability issues mainly related to moisture and oxygen contamination, that hinder their widespread as a single-junction PV technology.…”

Solar cells (SCs) are the most ubiquitous and reliable energy generation systems for aerospace applications. Nowadays, III–V multijunction solar cells (MJSCs) represent the standard commercial technology for powering spacecraft, thanks to their high‐power conversion efficiency and certified reliability/stability while operating in orbit. Nevertheless, spacecraft companies are still using cheaper Si‐based SCs to amortize the launching costs of satellites. Moreover, in recent years, new SCs technologies based on Cu(In,Ga)Se2 (CIGS) and perovskite solar cells (PSCs) have emerged as promising candidates for aerospace power systems, because of their appealing properties such as lightweightness, flexibility, cost‐effective manufacturing, and exceptional radiation resistance. In this review the current advancements and future challenges of SCs for aerospace applications are critically discussed. In particular, for each type of SC, a description of the device's architecture, a summary of its performance, and a quantitative assessment of the radiation resistance are presented. Finally, considering the high potential that 2D‐materials (such as graphene, transition metal dichalcogenides, and transition metal carbides, nitrides, and carbonitrides) have in improving both performance and stability of SCs, a brief overview of some important results concerning the influence of radiation on both 2D materials‐based devices and monolayer of 2D materials is also included.

“…In 2020, Dat et al, [6] carried out the nonlinear stability of nanocomposite multilayer organic solar cell subjected to axial compressive loads in which the model of organic solar cell is assumed to consist four functional layers as Al, P3HT:PCBM, PEDOT:PSS and IOT, and glass substrate. By analyzing the types and mechanism of inorganic perovskite film defects, the influence of inorganic perovskite film preparation technique on crystallization in recent years is reviewed, passivation strategies for different kinds of additives are discussed in combination with Lewis acid base theory, and interface engineering on both sides of the perovskite film is summarized in the work of Han et al, [7].…”

In this work we investigated the nonlinear vibration of nanocomposite multilayer perovskite solar cell (NMPSC) subjected to the combination of mechanical and thermal loadings. The model of organic solar cell is assumed to consist seven functional layers: Au, Spiro-OMeTAD, PEDOT:PSS, Graphene oxide, MAPbI3, TiO2 and IOT, and glass substrate. The governing equations are established basing on the classical plate theory taking into account the effect of elastic foundations and initial imperfection. Four edges of the NMPSC are assumed to be supported immovably in a transverse plane. The relationship between deflection amplitude and time as well as the expression of natural frequency of NMPSC are obtained by using the Galerkin and Runge – Kutta methods. The numerical results showed that the nonlinear dynamic response and the natural frequency of NMPSC have been strongly influenced by the geometrical and material parameters, initial imperfection, temperature increment and elastic foundations.
