“…X-ray and ultraviolet photoelectron spectroscopy can measure the change in the Fermi level position of materials, effectively indicating the change in doping level and type of perovskite materials [34,35] . In addition, Kelvin probe force microscopy (KPFM) can measure the contact potential difference of the semiconductor surface and obtain the change in the work function [36,37] . KPFM can be sensitive to the surface condition of perovskite materials, so the error caused by surface contamination and other factors should be eliminated before taking the measurements.…”

Organometallic halide perovskites have rapidly become promising materials as a result of their outstanding properties in high-efficiency and low-cost next-generation solar cells. Perovskite materials can be adjusted to be p- or n-type by defect engineering through, for example, the self-doping method by controlling the precursor compositions and process conditions. Recently, a p-type perovskite/n-type perovskite homojunction has been proposed and constructed, which provides a possibility for the design of a novel type of perovskite solar cell (PSC). Following a brief overview of the physical fundamentals of perovskite homojunctions, a detailed discussion of the promising progress of recently reported homojunction PSCs is presented here, including theoretical simulations, extrinsic and interfacial doping and graded structures. Furthermore, the opportunities regarding higher doping concentrations, simpler device architectures, ion migration inhibition and device stability are discussed. Finally, an outlook that offers insights into the future development of highly efficient and stable homojunction PSCs is provided.

“…It can be seen that for a defect density of 10 10 cm −2 to 10 12 cm −2 , the device parameters vary very little; but beyond 10 12 cm −2 , they start to decrease due to the fact that interface defects behave as recombination centers ( Ahmed et al, 2021 ). Moreover, the largest generation of electron-hole pairs occurs at the perovskite/TiO 2 interface; which is also accompanied by a higher recombination rate ( Sengar et al, 2021 ). We choose an optimal defect density equal to 10 12 cm −2 and this leads to the following electrical parameters:

“…Sol–gel technology has outstanding advantages in large‐area, low‐cost film formation, and the technology is much developed. [ 45 ] It is currently the mainstream technology of photovoltaic glass ARC. [ 46 ] It can estimate the porosity of the thin film, so as to achieve the purpose of regulating the refractive index of the thin film.…”

“…The reaction temperature, pH value, and the concentration of surfactants are all effect of refractive index of the mesoporous films. [43][44][45] We used this method to prepare a single-layer mesoporous silica film. We linked the FEM and the equivalent medium theory (EMT) to design an ARC with a mesoporous structure for the first time, and combined it with PSCs.…”

It is anticipated that perovskite solar cells (PSCs) will overtake other products in the market for next‐generation photovoltaics. The optical loss, however, continues to be a flaw that restricts the photocurrent (Jph) of PSCs. Mesoporous antireflection coatings (ARCs), both monolayer and multilayer, are designed using a combination of the finite element method and equivalent medium theory, and ARCs models are merged with PSCs. In the current work, mesoporous ARCs are made, the optical performance of the device is evaluated using optical modeling, and then the ARCs are integrated into solar cells. The simulation results show that the Jph of planar inverted PSCs can increase to 24.00 mA cm−2 when the front surface of PSCs adopts mesoporous ARC (via parameter optimization and sensible arrangement and combination). An increase of 0.98 mA cm−2 in Jph of PSCs is observed in comparison with flat ARC (23.02 mA cm−2). The strong light transmission and low reflection properties of the mesoporous ARCs are confirmed by the optimized solution. It is important to note that the first fusion of mesoporous and multilayer ARC offers a fresh approach to the development of perovskite and perovskite/silicon tandem solar cells with extremely high efficiency.
