“…It can be seen from the energy level diagram of the device that the CB of TiO 2 is lower than that of CsPbBr 3 , allowing electrons to be transferred from CsPbBr 3 to TiO 2 . [ 45 ] The VB of NiO x is higher than that of CsPbBr 3 so that holes are transferred from CsPbBr 3 to NiO x . Therefore, most electrons will be injected into TiO 2 from perovskite, and most holes will be injected into NiO x .…”

CsPbBr3 film possesses high stability and easy manufacturing characteristics, rendering it attractive for applications in perovskite solar cells (PSCs). However, optical loss and energy level matching of different material layers are still the major factors, limiting the performance of PSCs. Herein, the finite element method (FEM) and density functional theory (DFT) calculations composed of simulation interaction technology are used to study the effects of different electron transport layer and hole transport layer materials on the optical performance of different PSC configurations. The effect of the charge transport layer (CTL) material and CsPbBr3 on the energy level matching and charge transport of the device is explained. The FEM simulation results show that inorganic CTL materials produce less parasitic absorption than the organic materials. The DFT calculation results give the microscopic design rules of the CTL material. In addition, PSCs with a light‐trapping structure are designed, which effectively suppressed surface reflection. Finally, through the screening of CTL materials and the design of advanced light‐trapping structures, the photocurrent of PSCs is increased by 69.8% (from 5.30 to 9.00 mA cm−2). This work provides a novel model for the screening of CTL materials for inorganic PSCs.

“…The TiO2 layer is a well-known electron transporting layer (ETL) and its role is to transport electrons in the solar cell and serve as a hole blocking layer (HBL) to reduce charge recombination and prevent electrode shorting [27]. Similarly, NiO functionalizes as 59 a hole transporting layer [28]. An excited (electron-hole pair) is 60 generated in the active layer due to absorption of light.…”

Thanks to recent advancements in nanofabrication and 2 3D packaging, typical Internet of Things (IoT) devices can now be 3 wirelessly controlled using millimeter scale sensors known as 4 Internet of Tiny Things (IoT²) devices. Since these low power devices 5 may be exposed to low and indirect solar irradiation, we demonstrate 6 a novel meso-superstructured solar cell (MSSC) that allows low flux 7 light to be harvested from both its top and bottom sides. Our cell is 8 based on either a dye-sensitized solar cell (DSSC) or a perovskite 9 solar cell (PSC). The active layer in the proposed MSSCs was tuned 10 to allow semi-transparent behavior. Moreover, we developed an 11 experimentally validated model that enables optimization of the 12 active layer thickness for different semi-transparent MSSC 13 applications. In MSSCs, such optimization is necessary to balance 14 the trade-off between transparency and efficiency for various active 15 layer thicknesses. Fabricated DSSCs and PSCs cells were used to 16 validate the simulation results. The fabricated DSSC achieved a 17 harvesting ratio of 1:10 with a conversion efficiency of around 2% at 18 one Sun. We demonstrate that the optimum thickness of the 19 mesoporous TiO2 active layer in DSSCs was 800 nm, enabling a 20 maximum power density of 7 mW/cm 2 .

“…[5,6] Furthermore, gallium arsenide (GaAs), indium phosphide, and other single-crystal semiconductor films are model materials in modern microelectronic industries. [7,8] Beyond these canonical systems, there is high demand to expand these methods to preparing single crystal thin films of emerging semiconductors such as halide perovskite ABX 3 materials (e.g., MAPbX 3 , FAPbX 3 and CsPbX 3 , where MA + is CH 3 NH 3 emitting properties [30,31] and is more stable than MAPbX 3 , [32] leading to applications in photodetectors and LED devices. [33,34] For example, Li et al demonstrated that controlling surface ligand density on CsPbBr 3 perovskite quantum dots can lead to a 50-fold improvement external quantum efficiency in lightemitting diodes incorporating the nanoparticles.…”

Halide perovskite single crystal (HPSC) films have demonstrated extraordinary performance in solar cells, photodetectors, and lighting applications, owing to the high carrier mobility, long carrier diffusion length, tunable bandgap, and large light absorption coefficients of these materials. Here, the recent development of the major HPSC thin films is reviewed systematically, including MAPbI3, α‐FAPbI3, MAPbBr3, CsPbBr3, with special emphasis on different classes of fabrication methods and thin‐film characteristics. Finally, the conclusion and prospects in this field are discussed in detail. It is anticipated that the HPSC thin films will lead to a compelling future for the rising electronic applications.
