High-performance colorful semitransparent perovskite solar cells with phase-compensated microcavities

引用

nano Research 2018年第5期11卷 2553-2561页

作者： Kyu-Tae Lee Ji-Yun Jang na Young ha Soonil Lee Hui Joon Park Department of Materials Science and Engineering University of Illinois Urbana Illinois 61801 USA Department of EnergySystems Research Ajou University Suwon 16499 Republic of Korea Department of Electrical and Computer Engineering Ajou University Suwon 16499 Republic of Korea

We demonstrate highly efficient multi-colored semitransparent perovskite solar cells that can create high angular tolerant controllable transmissive colors up to 60~, based on phase-compensated microcavities. The efficiency of the semitransparent colors was improved by impedance matching, which was enabled by placing a dielectric functional layer on top of traditional optical microcavities, with negligible influence on color pureness. The vast majority of the visible part of solar radiation is efficiently utilized for solar energy harvesting, achieving 10.47%, 10.66%, and 11.18% of efficiency for red, green, and blue （RGB） colored solar cells, respective136 while a very small proportion of the visible solar spectrum is used for structural coloration that can be readily tuned by altering the cavity medium thickness. The approach described herein can be suitable for a variety of applications such as display systems with ultra-low power consumption, highly efficient colorful solar panels, low-power wearable electronics, and energy-efficient optoelectronics.

Application of powdered activated carbon coating to fabrics in a hybrid filter to enhance mercury removal

引用

Journal of Environmental Sciences 2019年第6期31卷 58-65页

作者： Jin-Ho Sung Seung-Ki Back Eun-Song Lee ha-na Jang Yong-Chil Seo Youn-Suk Kang Myong-Hwa Lee Department of Environmental Engineering Yonsei University J-E Tech Co. Ltd Department of Environmental Engineering Kangwon National University

Elemental mercury(Hg0) is predominant constituent of flue gas emitted from coal-fired power plants. Adsorption has been considered the best available technology for removal of Hg0 from flue gas. However, adsorbent injection increases the amount of ash generated. In the present study, powdered activated carbon(PAC) was coated on polytetrafluoroethylene/glass fiber filters to increase Hg0 removal while concurrently reducing the amount of ash generated. The optimal PAC coating rate was determined in laboratory experiments to ensure better Hg0 removal with low pressure drop. When PAC of particle size less than 45 μm was used, and the areal density was 50 g/m2, the pressure drop remained under 30 Pa while the Hg0 removal efficiency increased to 15.8% from4.3%. The Hg0 removal efficiency also increased with decrease in filtration velocity. The optimal PAC coating rate was applied on a hybrid filter(HF), which was combined with a bag filter and an electrostatic precipitator in a single chamber. Originally designed to remove fine particulates matter, it was retrofitted to the flue gas control device for simultaneous Hg0 removal. By employing the PAC coating, the Hg removal efficiency of the HF increased to 79.79% from 66.35%. Also, a temporary reduction in Hg removal was seen but this was resolved following a cleaning cycle in which the dust layer was removed.
