Study of Interfacial Effect in Nanowire with 2D Material Encapsulated System Using DFT Calculation
Yun-Ping Chiu, Chi-Yuan Kuo, Chih-I Wu, Yuh-Renn Wu, National Taiwan University (Taiwan)
Recent research has made 2D materials cladding a key player in enhancing nanowire performance by reducing electromigration (EM) and surface roughness scattering (SRS). Using the DFT method, this study explored Cu, Al, and Co metals with graphene, h-BN, and MoS2 interface. Projected band structure and electrostatic potential result indicate Cu and Al primarily exhibit physical adsorption, and Co mainly forms chemical adsorption. The Co-graphene system demonstrated superior SRS suppression, and the anchor effect serves additional EM resistance, offering wire performance enhancements.

Thick Molybdenum Disulfide Film Growth and Photovoltaic Responses of Vertical 2D Material Devices
Zhi-Wei Chen, National Yang Ming Chiao Tung University (Taiwan), Academia Sinica (Taiwan); Yu-Han Huang, Academia Sinica (Taiwan), National Taiwan University (Taiwan); Po-Tsung Lee, National Yang Ming Chiao Tung University (Taiwan); Shih-Yen Lin, Academia Sinica (Taiwan)
This report discusses the growth mechanism due to the unique properties of multilayer 2D materials combining organic and semiconductor materials. Controlling the time of sputtering Mo, MoS2 with different layers can be grown from monolayer up to above 15 layers. Then, by identifying HRTEM, it can be found that when MoS2 reaches more than 15 layers, there are some clusters in the layered structure, so the stacking layered MoS2 becomes messy. Therefore, we chose 10 layers MoS2 to fabricate 2D solar cells and found that its spectral response has an obvious cut-off at near 700 nm under zero bias.

Modeling and Understanding of Industrial Bifacial Passivated Contacts Solar Cells With SiC/SiO2 as Front Transparent Passivated Contacts
Jin-Cheng Chen, Yi-Ping Lin, You-An Li, Wei-Shan Hong, National Yang Ming Chiao Tung University (Taiwan); Han-Chen Chang, Industrial Technology Research Institute (Taiwan); Ying-Yuan Huang, National Yang Ming Chiao Tung University (Taiwan), National Cheng Kung University (Taiwan)
This research investigates the prospective performance of SiC/SiO2 as front transparent passivated contacts in industrial bifacial passivated contacts solar cells using Sentaurus TCAD for optical raytracing and Quokka2 for electrical simulations. Our simulations suggest an estimated efficiency improvement of approximately 2.4% for front SiC/SiO2 passivated contacts as compared to poly-Si/SiO2 front contacts. The simulations further indicate the possibility of achieving a remarkable performance of approximately 25% through industrial-compatible processes with the proposed bifacial passivated contacts structure.

Optical Stability Analysis of Antireflection Coating with Alumina Capping Layers Deposited by Electron-Beam Evaporation
Zi-Long Wei, BASO Precision Optics LTD. (Taiwan), Feng Chia University (Taiwan); Chien-Jen Tang, Feng Chia University (Taiwan)
Antireflection coating produced using the electron gun evaporation undergoes reflectance spectra changes over time, resulting in variations in the reflectance spectra converted to CIE xy. Through analysis using the Essential Macleod Software, the reasons for these changes were identified, and a new method was proposed to stabilize the reflectance spectra and chromaticity coordinate.
