In accordance with the IEC 61215-2: 2021 standard, we analyzed the factors that affect the measurement of PID performance, including the effects of a light soak of the p-type gallium (Ga)-doped silicon mono-facial PV modules, the resistivity of the water used for humidification of the environmental chamber, and the relative humidity of the chamber. We also examined the change of the modules’ anti-PID performance under the erosion by NaCl solution and by higher humidity combined with NaCl solution. The results show that a light soak pre-treatment before the PID test of the module leads to a difference of 0.02% in average power loss. The influence of humidifying water with different resistivities used in the environmental chamber on the PID test is negligible. An increase in humidity substantially reduces the anti-PID performance of the module. When the EVA film thickness was reduced from 0.65 mm to 0.55 mm, the power loss increased from 2.25% to 3.96% after the PID test. In addition, NaCl on the backsheet of the module could accelerate the PID effect under applied electric field conditions, resulting in the formation of localized darkening area observed under electroluminescence (EL) image. Finally, after the PID test in the presence of higher humidity and NaCl solution, the average power loss of the modules amounted to 10.80%, while it was 1.29% for the modules after the standard PID test. Therefore, it is vital to improve the anti-PID performance of mono-facial PV modules in a high relative humidity and salt-mist environment.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142386225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation results for an epoxy molding compound (EMC) with viscosity of 0.448 kg/m·s were validated by an experiment. A grid independence test was run to determine the minimum mesh refinement required for the simulation. The results revealed that the final fluid profile of the EMC at 0.448 kg/m·s conformed more closely to the experimental results than the other epoxies. The overall best performance of the wire configuration to the EMC on the LED encapsulation process, in descending order, was the square-loop, triangle-loop, S-loop, Q-loop, and M-loop.

For this purpose, the plane wave self-consistent method was used. Using the Brich–Murnaghan equation, their electronic structure and magnetic ordering were also investigated. It was understood that, under pressure, the compound SrFe2As2 undergoes a structural phase change from the tetragonal phase into the collapsed tetragonal phase. Further, due to their larger lattice constants, antimonides with larger local iron magnetic moment exhibit an enhanced Hund's rule coupling. Furthermore, smaller intra-atomic exchange coupling and significantly smaller lattice constants may be the cause of the extremely small local Fe moment for phosphates. The analysis of the valence charge density in the collapsed tetragonal phase demonstrates that the interactions between As atoms are more pronounced when compressed along the c-axis. The strength of this interaction is primarily governed by the Fe-As chemical bonding. The collapsed tetragonal phase of SrFe2As2 compounds, as observed in Fermi surface studies, indicates the absence of nesting of Fermi surfaces. It is clear that, from the studies, the tetragonal phase of Fermi surface nesting resulted in the long-range magnetic order, leading to the presence of superconductivity.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142248516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, our capacity to carry out remote monitoring has been constrained by our past dependence on specialized electronic equipment for assessing vital signs such as heart rate (beats per minute [BPM]) and oxygen saturation (SpO2). To address this issue, we developed an innovative technology that makes use of internet connectivity to allow for remote vital sign measurement and monitoring.

In this work, the strain effects on the structural, electronic, and thermal transport properties of the γ-graphyne and twin graphene sheets have been systematically clarified through first-principles calculations. Regardless of the geometrical similarities of the two considered 2D carbon allotropes, our results indicate that the acetylenic linkages in the γ-graphyne and the AA-stacked aromatic rings in the twin graphene are capable of resulting in the notable deviations in their electronic and thermal transport properties, as well as the strain-dependent behaviors. Both of the two sheets possess an intrinsic semiconducting nature with a tunable direct bandgap that depends on the biaxial strains. The thermal conductivity of the γ-graphyne is significantly suppressed compared to the twin graphene counterpart. Moreover, the heat transfer of the two sheets can be further enhanced by the tensile strains, and a dramatic increase can be obtained in the strained γ-graphyne sheet. Thus, the effectively tunable electronic and thermal transport properties revealed in this work imply the great potential of the two 2D carbon allotropes, and the comparative study also uncovers the structural effect of the carbon networks on their novel properties and strain responses.","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142248515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
