Abstract Flexible and transparent thin-film silicon solar cells were fabricated optimized for building-integrated photovoltaics bifacial operation. A laser lift-off method was developed to avoid thermal damage during the transfer of light-scattering structures onto colorless polyimide substrates thus enhance front-incidence photocurrent, while a dual n-type rear window layer introduced reduce optical losses, facilitate electron transport incidence, performance The introduction increased...

Color implementation in flexible photovoltaics (PVs) is aesthetically important modern vehicles and buildings. To implement color PVs using conventional distributed Bragg reflector (DBR) methods, it necessary to reduce its brittleness minimize the light loss due refractive index differences (Δn). Here, color-implemented transparent front electrodes for solar cells (FTSCs) have been proposed an aluminum-doped zinc oxide (AZO)–based multilayer with periodic hydrogenation (AZO:H). The of AZO...

Transparent hydrogenated amorphous silicon solar cells were fabricated using a p-type window layer of molybdenum oxide (MoOx) for building-integrated photovoltaic (BIPV) windows. The MoOx was prepared with oxygen flow ratios from 0.03 to 0.21 by reactive sputtering, and the PV performance improved an ratio 0.09 because lower carrier recombination parasitic absorption in p layer. Additionally, we optimized cell introducing bilayer, power conversion efficiency bilayer enhanced boosted open...

We fabricated a colored transparent thin-film silicon solar cell (TSC) using distributed Bragg reflector (DBR) electrode for building-integrated photovoltaics (BIPVs). To construct DBR electrode, indium tin oxide (ITO) and aluminum-doped zinc (AZO) were optimized with the variation of oxygen incorporation considering optical electrical properties in reactive sputtering deposition, their refractive index difference was about 0.12 at wavelength 480 nm, which generate low reflection loss TSCs....

국내에는 과일류 중 중금속의 기준규격은 없으나, Codex에서는 납 함량 규격을 0.1 mg/kg으로 설정하여 관리하고 있다. 이에 따라 우리나라에서 유통 중인 과일류의 중금속 설정하고자 일일 섭취량이 많은 과일 8종(오렌지, 사과, 바나나, 배, 감귤, 감, 망고, 키위), 927건을 수거하여 납, 카드뮴, 비소 및 수은 함량을 수은분석기 ICP-MS를 이용하여 분석하였다. 표준용액첨가법에 의한 회수율은 86.0-110.4%, 카드뮴 81.0-104.0%, 82.0-104.7%를 얻었으며, 수은분석기를 이용한 수은의 106.5%이었다. 조사결과 국내유통 평균함량은 8.3, 0.7 1.4, <TEX>$0.3{\mu}g/kg$</TEX>으로 조사되었다. 주간섭취량을 FAO/WHO에서 안전성 평가를 위해 설정한 PTWI와 비교한 결과, 수은이 각각 0.17, 0.013 0.006%로 그 수준이 매우 낮아 유통되는 이들 과일로부터 섭취하는 중금은 미미하여 안전한 수준으로 판단된다....

A novel approach to fabricating a transparent and flexible one-transistor–one-diode (1T-1D) image sensor array on colorless polyimide (CPI) film substrate is successfully demonstrated with laser lift-off (LLO) techniques. Leveraging indium tin oxide (ITO) electrodes amorphous gallium zinc (a-IGZO) channel-based thin-film transistor (TFT) backplanes, vertically stacked p-i-n hydrogenated silicon (a-Si:H) photodiodes (PDs) utilizing low-temperature (&lt;90 °C) deposition process are integrated...
