Over a short period of approximately 10 years, metal‐halide‐perovskite‐based photovoltaics have demonstrated unprecedented improvements in solar cell performance beyond the various major photovoltaic semiconductor materials such as organic, cadmium telluride, and copper indium gallium selenide. With this, the current focus lies on the commercialization of perovskite solar cell technology and the issues encountered while ensuring and balancing high efficiency, stability, and eco‐friendliness in the photovoltaic community. This article reviews prominent developments in perovskite‐based photovoltaic power generation based on the ABI3 structure, describing the current state and understanding of state‐of‐the‐art solar cell drives. Accordingly, methods to improve the efficiency and long‐term operational stability, lead toxicity, nonlead perovskites, bandgap optimization, and tandem solar cells are discussed. Prospects and views on future research considering the feasibility of perovskite technology commercialization are provided.

up, but their weaknesses (bad stability and low efficiency) are obvious although it is expected as a promising candidate to address the toxicity of lead. [33] There are at least four main issues to be solved: i) The poor stability due to the oxidation of Sn 2+ in a low water and oxygen environment.ii) The low formation energy of Sn vacancies. iii) The fast formation rate of perovskite leads to poor film formation quality. iv) The mismatch of energy levels between SOIHP layer and the charge transport layer results in the charge transport barrier. [34] Therefore, it is urgent to resolve these problems in the POIHPs and SOIHPs to improve their performance, promoting the commercial application of perovskites in many fields. In order to address the issues aforementioned, compositional engineering plays a key role in achieving highly efficient and stable OIHPs. Notably, the modification of properties through ion doping is an effective way to improve the performance and broaden the application field of OIHPs in recent years, [1,[35][36][37][38][39][40] involving solar cells, light-emitting diodes, transistors, and so on. [1,4,6,41] In order to better understand doping, it is important to study the structural characteristics of perovskites. There are two main kinds of perovskites 3D and 2D perovskites, which were extensively explored in recent years. The typical 3D structure can be expressed as ABX 3 , where A is an organic cation such as CH 3 NH 3 + (MA), (NH 2 ) 2 CH + (FA), and Cs + ; B is a divalent cation such as Pb 2+ and Sn 2+ (we only mentioned in this article); X is halogen anions such as Cl − , Br − , and I − , respectively. The 2D perovskites can be categorized as Ruddlesden-Popper phase (RPP) A' 2 A n-1 B n X 3n+1 with 1 ≤ n < ∞, Dion-Jacobson phase (DJP) A''A n-1 B n X 3n+1 with 1 ≤ n < ∞, and alternating cations in the interlayer phase (ACIP) A'''A n B n X 3n+1 , where the A', A'' and A''' are an organic spacer cation such as aromatic or aliphatic alkylammonium monovalent cations; diamine compounds with two amino groups forming hydrogen bonds on both ends with the inorganic "quantum wells" (bivalent cations), and guanidine (GA), respectively. [1,[42][43][44] There are also lower-dimension (LD) perovskites such as 1D and 0D. [45][46][47] The ions doping can occur at the A, B, and X sites, or simultaneously happen at these sites. The doping that we mentioned in perovskite may differ from other semiconductors where it refers to a very small concentration of element addition, while our "doping" refers to a large amount of element addition which is more like an alloy or so. With the different doping strategies, the properties of POIHP and SOIHP can be effectively controlled or modified. The relationship between the

“…Conversely, the peak intensity of ε 2 decreases with Sn doping because of the decrease in the electron transition probability. It can be seen from PDOS, 62 where the value of Sn 5s involved in the High temperatures can accelerate the light-induced degradation of perovskites, 4 such as MAPbI 3 to PbI 2 . 64 The hightemperature optical data considered in this work is for PbI 2 after the degradation and stabilization of MAPbI 3 at 473 K (see Figure S12 in Supporting Information).…”

The encapsulation of hybrid perovskite in nanoporous GaN is a promising strategy to reduce perovskite degradation and improve photoelectric performance. Exploitation of the intrinsic light-matter interaction in such a composite structure greatly benefits improving device optimization. Herein, we report the perovskite synthesis, structural design, and radiative properties of perovskite/nanoporous GaN hierarchical composites using spectroscopic ellipsometry (SE) experiments as well as electromagnetic simulations. Firstprinciples calculations reveal the relationship between electronic interband transitions and the dielectric function of perovskite measured by SE. We use the finite-difference time-domain (FDTD) and finite-element method (FEM) simulations to analyze the spectral radiation properties for the hierarchical composite structure in terms of both morphology dependence and material factors. The optical absorption peaks in the near-infrared−visible region are collectively determined by the nanopore size, layer thickness, and incident angle of light. Also, the optical absorption distribution patterns are related to variables of the halogen, metal elements, and temperature. This work is integrated with the development of perovskite-based applications for solar functional batteries, light-emitting diodes (LED), and optoelectronic detectors.
