3D Bioinspired Hair‐Based Solar Evaporator for Efficient Water Harvesting

Advanced Functional Materials, EarlyView.
A bio‐derived solar evaporator inspired by blackbody radiation is developed using human hair waste. The vertically aligned hair structure enables broadband light absorption, efficient thermal localization, and rapid water transport, achieving high evaporation rates and stable desalination performance.

UV Degradation and Recovery of Perovskite Solar Cells

Scientific Reports, 2016
Although the power conversion efficiency of perovskite solar cells has increased from 3.81% to 22.1% in just 7 years, they still suffer from stability issues, as they degrade upon exposure to moisture, UV light, heat, and bias voltage. We herein examined

NLTE solar irradiance modeling with the COSI code

, 2010
Context. The solar irradiance is known to change on time scales of minutes to decades, and it is suspected that its substantial fluctua- tions are partially responsible for climate variations. Aims.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Observed solar near UV variability: A contribution to variations of the solar constant [PDF]

Continuous Measurements of the Solar UV have been made by an instrument on the Solar Mesosphere Explorer (SME) since October 1981. The results for the wavelength interval 200 to 300 nm show an irradiance decrease to a minimum in early 1987 and a ...

X-Raying the Dark Side of Venus - Scatter from Venus Magnetotail?

, 2016
This work analyzes the X-ray, EUV and UV emission apparently coming from the Earth-facing (dark) side of Venus as observed with Hinode/XRT and SDO/AIA during a transit across the solar disk occurred in 2012. We have measured significant X-Ray, EUV and UV
