Korean J. Met. Mater. 2019;57(8):535-542.   Published online 2019 Jul 4
DOI: https://doi.org/10.3365/KJMM.2019.57.8.535

Abstract
We investigated the effects of materials and the film thickness of hole transport layers (HTLs) on inverted type perovskite solar cells using optics-charge transport coupled simulations. Power conversion efficiencies (PCEs), and the variations in efficiency induced by the film thickness dispersion, were intensively studied, to compare potential HTLs candidates like..... More

Korean J. Met. Mater. 2019;57(7):456-461.   Published online 2019 Jun 5
DOI: https://doi.org/10.3365/KJMM.2019.57.7.456

Abstract
The photovoltaic properties of perovskite solar cells (PSCs) were investigated by adding graphene oxide (GO) to the electron transport layer of TiO2. The PSCs were fabricated with a glass/FTO/BL-TiO2/meso-TiO2 + GO/perovskite/HTL/Au electrode structure by adding various contents of GO (0.0, 0.3, 0.5 and 0.7 wt%) to the TiO2 layer. To..... More

A Study of Silicon Crystallization Dependence upon Silicon Thickness in Aluminum-induced Crystallization Process
Doo Won Lee, Muhammad Fahad Bhopal, Soo Hong Lee
Korean J. Met. Mater. 2018;56(5):400-405.   Published online 2018 May 8
DOI: https://doi.org/10.3365/KJMM.2018.56.5.400

Abstract
Aluminum-induced crystallization(AIC) is one of the ways to improve characteristics of thin-film poly-crystalline (TFPC) silicon solar cell since it shows large grain size and good properties for TFPC silicon solar cell. In AIC process, aluminum is firstly deposited on foreign substrate. Then, silicon is deposited on aluminum. Annealing was done..... More

Korean J. Met. Mater. 2017;55(9):637-644.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.637

Abstract
In the photovoltaic industries, the main technique of metallization is screen printing with silver pastes, due to its simple and quick process. However, the high price of silver paste is one of the barriers to the producing of low cost solar cells. Consequently, a primary target in photovoltaic research is..... More
