Journal ArticleDOI
Effect of Series Resistance on Field-Effect Mobility at Varying Channel Lengths and Investigation into the Enhancement of Source/Drain Metallized Thin-Film Transistor Characteristics
Nguyen Van Duy,Kyunghyun Baek,Dang Ngoc Son,Wonbaek Lee,Kwang-Ryul Kim,Byoungdeog Choi,Hokyun Chung,Junsin Yi +7 more
TL;DR: In this paper, the effect of parasitic resistance along the source and drain electrodes on the field-effect mobility of thin-film transistors was investigated and solutions for the reduction of this unexpected resistance were studied.
Journal ArticleDOI
Mechanical property evaluation according to alumina content of aged porcelain insulator
Keekeun Kim,Byungwoo Moon,Damhyun Kim,Kibum Park,Chang-Sung Seok,Taeyong Kim,Junsin Yi,In-Hyuk Choi +7 more
TL;DR: In this paper, the effect of microstructure on mechanical properties and aging characteristics based on the alumina content of porcelain was analyzed via X-ray diffraction, and the change in corundum content was quantitatively analyzed via scanning electron microscopy and an image-analysis program.
Journal ArticleDOI
High-efficiency hybrid solar cell with a nano-crystalline silicon oxide layer as an electron-selective contact
A. A. Cherkashina,Muhammad Quddamah Khokhar,Shahzada Qamar Hussain,Sanchari Chowdhury,Muhammad Aleem Zahid,Duy Phong Pham,Sungjin Jeong,Sungheon Kim,Sangho Kim,Eun-Chel Cho,Junsin Yi +10 more
Journal ArticleDOI
Improved efficiency of perovskite-silicon tandem solar cell near the matched optical absorption between the subcells
TL;DR: In this paper, a MAPbI3-based top and heterojunction with intrinsic thin layer silicon (HIT) bottom subcell was investigated, where a relatively low thickness (150 nm) of the perovskite absorber layer was found optimum for the top-subcell to achieve best efficiency of the tandem cell.
Journal ArticleDOI
Selective emitter using a screen printed etch barrier in crystalline silicon solar cell.
Kyuwan Song,Bonggi Kim,Hoongjoo Lee,Youn-Jung Lee,Cheolmin Park,Nagarajan Balaji,Minkyu Ju,Jae Woo Choi,Junsin Yi +8 more
TL;DR: This work suggests that the contact resistance of the selective emitter can be controlled by wet etching with the commercial acid barrier paste that is commonly applied in screen printing.
