“…Although FA + and Cs + based perovskite are difficult to maintain the photoactive phase at room temperature, incorporating cation with different ionic sizes is an effective method to balance the Goldschmidt tolerance factor and to stabilize the FA + and Cs + based perovskite crystal structure . A large A‐site cation in perovskite is believed to enhance the thermal stability of perovskite crystal structure due to its size effect and high boiling point . Incorporation of a small amount (≈5 mol%) of large size cation will induce minute lattice distortion, thus increasing the activation of ion migration.…”

Ion migration in organometal halide perovskite solar cell (OHPSC) and crystal structure evolution of organometal halide perovskites (OHPVSKs) in air are considered as one of the critical factors for unstable performance and of the urgent issues for the reliability of OHPSCs. Herein, a novel cation of acetamidinium (Aa+) with stronger coordinated bond with I− than methylammonium is induced into OHPVSK to stabilize its crystal structure. By incorporating Aa+ ions into OHPVSKs, the power conversion efficiency (PCE) of OHPSC without an encapsulation can maintain higher than 75% of its initial PCE after a 200 h humidity (60–80% relative humidity (RH) in air) or a 24 h thermal stress test (85 °C in dry N2). The Aa–MAPbI3 device exhibits an outstanding efficiency of 20.68%, and over 80% of initial PCE is maintained after a 1300 h damp heat as encapsulated. This novel cation can be easily incorporated into OHPVSK via a hot casting process in air with a high environmental tolerance as compared with that from the conventional coating process, which suffers from sophisticated crystallization steps and a strict processing atmosphere. It extends processing windows for OHPVSK fabrication and provides a promising path toward mass production and further commercialization.

“…A perovskite solar cell has a high absorption coefficient, and the photo-generated charge carriers present a large diffusion length compared to most of the thin-film solar cell materials [15]. Moreover, we are witnessing a progress in efficiency [16,17] and stability [18] of perovskite solar cells that is boosting the scientific interest. This type of cell requires a transparent conductive oxide (TCO) electrode for its operation as an energy harvester [19].…”

Narrow Absorption in ITO-Free Perovskite Solar Cells for Sensing Applications Analyzed through Electromagnetic Simulation

This work reports on a computational analysis of how a modified perovskite cell can work as a refractometric sensor by generating surface plasmon resonances at its front surface. Metal-dielectric interfaces are necessary to excite plasmonic resonances. However, if the transparent conductor (ITO) is replaced by a uniform metal layer, the optical absorption at the active layer decreases significantly. This absorption enhances again when the front metallic surface is nanostructured, adding a periodic extruded array of high aspect-ratio dielectric pyramids. This relief excites surface plasmon resonances through a grating coupling mechanism with the metal surface. Our design allows a selective absorption in the active layer of the cell with a spectral response narrower than 1 nm. The photo-current generated by the cells becomes the signal of the sensor. The device employs an opto-electronic interrogation method, instead of the well-known spectral acquisition scheme. The sensitivity and figure of merit (FOM) parameters applicable to refractometric sensors were adapted to this new situation. The design has been customized to sense variations in the index of refraction of air between 1.0 and 1.1. The FOM reaches a maximum value of 1005 RIU − 1 , which is competitive when considering some other advantages, as the easiness of the acquisition signal procedure and the total cost of the sensing system. All the geometrical and material parameters included in our design were selected considering the applicable fabrication constrains.

“…As compared to the condition of direct light irradiation, less resistance variation of the electrodes under the exposure of moisture or oxygen has been observed in Figure 6, despite the fact that the MAPbI 3 is vulnerable to both of the moisture and oxygen. [ 38,39 ] It is because the decomposition of MAPbI 3 and the followed decomposition of MAI are majorly happened on the top surface of perovskite film or between the crystal grains, and the I 2 gas will diffuse through pinholes existing among grain boundary to bottom silver nanowires. Different from the case of light irradiation, where the corrosion can happen at each contact site of silver nanowire and perovskite film, the diffusion of I 2 is majorly limited at the grain boundary for introducing relative less corrosive event on the silver nanowire electrode in the environment with moisture or oxygen.…”

for solar light injection and charges collection, the flexibility of which is also beneficial for the development of bendable and flexible photovoltaic devices. [9-12] The silver nanowire (AgNW) based transparent electrode with the merits of low-temperature solution-processed fabrication, outstanding optical/electrical property, and superior mechanical flexibility has been also adopted as the bottom or top electrode of perovskite solar cells. [13-18,42] However, the stability of metal electrodes, encountered with the corrosion and failure when adopted in organicinorganic perovskite solar cells, has been considered as the critical issue for their future application in this promising photovoltaic technique. [14,19] In addition, the reaction of halogen species from perovskite layer with metal electrode will also bring irreversible deterioration of the device performance. [20-22] Inserting electrical conductive and physical blocking material between the metal electrode and perovskite film has been proposed to improve the stability of metal electrode and the device performance. [23-26] Despite previous reports have mentioned various conditions, such as moisture, light, oxygen, etc., are critical to the stability of perovskite device, [27-31] less paper systematically study the corrosion of metal electrode by perovskite film and conventional halogen compounds for the precursor under different environmental conditions. In this paper, we would like to investigate the corrosion against the silver nanowire based transparent electrode by six halogen compounds of CH 3 NH 3 X (MAX) and PbX 2 (X = I, Br, Cl) and the perovskite film of CH 3 NH 3 PbI 3 (MAPbI 3) without and with holes transporting layer under four different environmental conditions, through monitoring the resistance variation of the electrode. The four conditions are set to be a dry nitrogen gas environment without light, dry nitrogen gas environment with light irradiation, wet nitrogen gas without light and nitrogen/oxygen mixture gas without light. X-ray diffraction (XRD) is also adopted to characterize the silver nanowire electrode after electrical resistance characterization. Experimental results demonstrate that both moisture and oxygen will promote the corrosion of MAI against the silver nanowire, as compared with the case of electrode under light irradiation. Since metal electrode is an important component in the perovskite solar cells, which can be used as back contact, transparent electrode, and the transparent interlayer of tandem devices, the corrosion of metal electrode by perovskite film, should be understood. Here, the corrosion of conventional reagents of organic-inorganic perovskite material, i.e., CH 3 NH 3 X (MAX) and PbX 2 , X = I, Br, and Cl, against silver nanowire (AgNW) based transparent electrode are investigated under four different environments, i.e., nitrogen protection, light irradiation, oxygen exposure, and moisture exposure, separately. The corrosion process is inspected by monitoring the time-dependent resistance variation of the ...
