“…All the MD simulations were conducted using the LAMMPS package [49] with periodic boundary conditions in three dimensions. The MYP potential [1][2][3]50,7] derived from first-principle calculations was used to describe the atomic interactions in MAPbI 3 with a timestep of 0.5 fs. The systems were equilibrated by the NPT ensemble relaxation at 350 K and 0 bar for 1 ns, and subsequently, by an NVE ensemble relaxation for 1 ns to fully relax these models.…”

“…Organic-inorganic hybrid halide perovskites, such as the prototypical CH 3 NH 3 PbI 3 (MAPbI 3 ), have attracted intensive attention as light absorbers in solar cells [1][2][3][4] , emitters in light emitting diodes (LEDs), [5] and thermoelectric materials [6,7] (Figure 1a) owing to solution-processability and high performance. In addition, facilitated by the movement of intrinsic iodine vacancy defects driven by applied voltage, [8] MAPbI 3 sandwiched between metal electrodes forms a memristor, and has been used in resistive switching memories [9] and artificial synapses.…”

Organic‐inorganic hybrid halide perovskites show a unique two‐channel thermal transport through propagons and diffusons, largely affecting other energy carriers for opto‐ and thermoelectric applications. Taking CH3NH3PbI3 as a prototype, the impact of iodine vacancy point defects on the two‐channel thermal transport is investigated using theoretical calculations and experimental validations. This work finds that iodine vacancies suppress the thermal transport in the propagon channel significantly, but less in the diffuson channel. This results in a weaker reduction of the total thermal conductivity (TC) than that predicted by the classical Klemens model. The TC reduction in the diffuson channel is mainly attributed to the declined vibrational density of states. Moreover, low‐frequency diffusons transformed from propagons compensate the reduction of TC in the diffuson channel, resulting in a dominant contribution from the diffuson channel to the total TC, which is 55% to 85% for 0% to 6% vacancy concentration. CH3NH3PbI3 also shows ultra‐defect‐tolerant diffusonic thermal transport, ≈1–2 orders of magnitude lower than diamond in the defect sensitivity factor. This work shows both scientific insights into the new two‐channel thermal transport mechanism in complex material systems with disorder, and technological significance on halide perovskites for solar cell, light‐emitting diode, thermoelectric, and memristor applications.

“…[2] The power conversion efficiency of hybrid perovskite solar cells has been shown to reach 26.1%, rivalling crystalline silicon cells. [3,4] Given the prerequisite that they are produced in an environmentally friendly manner, and that the assembly of a functional perovskite cell is as straightforward as positioning the perovskite absorber between an electron transport layer and a hole transport layer, perovskite solar cells appear to possess considerable promise for fostering sustainable growth. [2,5] The HOIP crystals in question are a form of the ABX 3 single perovskite structure.…”

Hybrid organic–inorganic perovskites (HOIPs) are promising candidates for next‐generation photovoltaic materials. However, there is a debate regarding the impact of interactions between the organic center and the surrounding inorganic cage on the solar cell's high diffusion lengths. It remains unclear whether the diffusion mechanism is consistent across various halide perovskite families and how light illumination affects carrier lifetimes. The focus is on ion kinetics of (CH3NH3)PbX3 (X = Br, Cl) perovskite halide single crystals. Muon spectroscopy (μ+SR)is employed to investigate the fluctuations and diffusion of ions via the relaxation of muon spins in local nuclear field environments. Within a temperature range of 30–340 K, ion kinetics are studied with and without white‐light illumination. The results show a temperature shift of the tetragonal‐orthorhombic phase transition on the illuminated samples, as an effect of increased organic molecule fluctuations. This relation is supported by density functional theory (DFT) calculations along the reduction of the nuclear field distribution width between the phase transitions. The analysis shows that, depending on the halide ion, the motional narrowing from H and N nuclear moments represents the molecular fluctuations. The results demonstrate the importance of the halide ion and the effect of illumination on the compound's structural stability and electronic properties.

“…As the potential of the passivated emitter and rear cell is exhausted, the widespread adoption of tunneling oxide passivation contact (TOPCon) solar cells is attributed to the ability to upgrade the manufacturing process on existing production lines. [1,2] Compared with TOPCon, silicon heterojunction (SHJ) technology possesses the advantages of simple processes, superior passivation, higher bifaciality, lower degeneration, and silicon consumption, etc., [3][4][5][6] which is attracting growing interest. Moreover, SHJ solar cells have achieved remarkable efficiency records, reaching 26.8% for the single-junction cell [7] and 33.9% for the perovskite/silicon tandem solar cell.…”

Although Ag‐coated Cu technology is considered to be an effective approach to mitigate the metallization expenses associated with silicon heterojunction (SHJ) solar cells, there is limited reporting on the photovoltaic performance and reliability of devices employing Ag/Cu electrodes. Here we have successfully fabricated industrial SHJ solar cells, yielding an average efficiency of 25.18% with bifacial Ag/Cu fingers, which caused a 0.13% decline in efficiency but saved 46% in Ag consumption when compared to traditional Ag fingers. Performance degradation is demonstrated to originate essentially from the front rather than rear Ag/Cu fingers, as revealed by a comprehensive analysis of resistance enhancement and optical loss. Notably, the Ag/Cu fingers exhibit a 1.4% lower printed qualification rate and similar high‐temperature stability in contrast to Ag fingers. Our results provide valuable insights for further optimization of low‐cost and high‐efficiency SHJ solar cells based on Ag/Cu electrodes.This article is protected by copyright. All rights reserved.
