Korean J. Met. Mater. 2021;59(1):67-72.   Published online 2021 Jan 5
DOI: https://doi.org/10.3365/KJMM.2021.59.1.67

The properties of 6 mM urea added perovskite solar cells (PSCs) according to ZrO2 electron transport layer (ETL) thicknesses of 204, 221, 254, and 281 nm were examined. A solar simulator was used to characterize the photovoltaic properties of the cell. Optical microscopy and field emission scanning electron microscope were..... More

Korean J. Met. Mater. 2020;58(1):59-66.   Published online 2019 Dec 12
DOI: https://doi.org/10.3365/KJMM.2020.58.1.59

The photovoltaic properties of TiO2/ZrO2 double electron transport layered perovskite solar cells were investigated based on the ZrO2 layer thickness. Samples were fabricated with a glass/FTO/TiO2/ZrO2/ perovskite structure. The TiO2/ZrO2 layer thickness ratio was confirmed to be 264/0, 228/168, 228/204, 270/242, and 282/288 nm, respectively, using an electron probe microanalyzer...... More

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

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

이혜령, 김광배, 송오성
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

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

Korean J. Met. Mater. 2018;56(4):321-326.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.321

Changes in the properties of the hole transport layer (HTL) and the perovskite layer in a perovskite solar sell (PSC) were observed under various Au thermal evaporation conditions. We employed a conventional thermal evaporator with a distance of 30 cm between the source and substrate in a vacuum of 6..... More
