the perovskite material onto transparent substrates covered with a compact TiO 2 layer and an optional mesoporous TiO 2 (or Al 2 O 3 ) scaffold layer. [34] The p-i-n structure, which involves depositing the perovskite material onto transparent substrates which are covered with an HTL, such as the poly(3,4-ethylene dioxythiophene):polystyrene sulfonic acid (PEDOT:PSS). [35] So far, PSCs based on both mesoporous and planar structure exhibit high performance and stability, however, the comparison of the advantages of two different strucutres in stability is still under debate. [36] Mesoporous Perovskite Solar CellsRecently, a new generation of photovoltaic converters, mesoporous solar cell [37] has attracted more consideration due to their low material cost, simple fabrication process, high energy conversion efficiencies, [38] like dye-sensitized solar cell, [38c] and mesoporous perovskite solar cell. [5a,21,39] PCE up to 9.7% has been achieved by using CH 3 NH 3 PbI 3 (MAPbI 3 ) perovskite nanocrystals as the light absorber to fabricate a solid-state MPSC. [21] After that the research focuses on solid-state MSCs began to transfer from DSSCs to MPSCs. [32a,40] In an MPSC, a compact layer is usually deposited on fluorine doped tin oxide (FTO) layer, which usually extracts electrons and block holes. Three strategies are broadly used for depositing the TiO 2 layer: 1) Spin-coating the colloidal dispersion of TiO 2 nanoparticles followed by a thermal treatment (titanium source: TiCl 4 , [41] titanium isopropoxide, [42] tetra-n-butyl-titanate; [43] 2) spin-coating titanium precursor solutions followed by a thermal treatment (titanium source: TiCl 4 , [44] titanium isopropoxide, [23] titanium diisopropoxide bis(acetylacetonate) 12 ); 3) spray pyrolysis deposition (titanium source: titanium diisopropoxide bis(acetylaceto nate) 18 ).

The recent rise of low-dimensional Ruddlesden-Popper (RP) perovskites is notable for superior humidity stability, however they suffer from low power conversion efficiency (PCE). Suitable organic spacer cations with special properties display a critical effect on the performance and stability of perovskite solar cells (PSCs). Herein, a new strategy of designing self-additive lowdimensional RP perovskites is first proposed by employing a glycine salt (Gly + ) with outstanding additive effect to improve the photovoltaic performance. Due to the strong interaction between CO and Pb 2+ , the Gly + can become a nucleation center and be beneficial to uniform and fast growth of the Glybased RP perovskites with larger grain sizes, leading to reduced grain boundary and increased carrier transport. As a result, the Gly-based self-additive lowdimensional RP perovskites exhibit remarkable photoelectric properties, yielding the highest PCE of 18.06% for Gly (n = 8) devices and 15.61% for Gly (n = 4) devices with negligible hysteresis. Furthermore, the Gly-based devices without encapsulation show excellent long-term stability against humidity, heat, and UV light in comparison to BA-based low-dimensional PSCs. This approach provides a feasible design strategy of new-type low-dimensional RP perovskites to obtain highly efficient and stable devices for next-generation photovoltaic applications.

“…10 Theoretically, the nature of ABO 3 perovskites can be explained by making use of density functional theory (DFT) calculations and this would lead to further exploration of the electronic structural properties. 31 In this work, we present a kinetic analysis of morin oxidation in the presence of perovskites containing transition metal cations. We aim at developing an understanding of the effect of electron-density distribution on a transition metal in the BO 6 coordination environment of the ABO 3 perovskite on reaction kinetics using density functional theory (DFT) calculations.…”
