Influence of the Solar Spectra Models on PACO Atmospheric Correction

open access: yesRemote Sensing, 2022
The solar irradiance is the source of energy used by passive optical remote sensing to measure the ground reflectance and, from there, derive the ground properties.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Optimization of multilayer anti-reflection coatings for efficient light management of PEDOT:PSS/c-Si heterojunction solar cells

open access: yesMaterials Research Express, 2019
In this paper, we present a theoretical model for the optimization of multilayer anti-reflection coatings for PEDOT:PSS/c-Si heterojunction solar cell based on optical interference transfer-matrix theory. A comprehensive idea of designing multilayer anti-

A method for monitoring solar diffuser’s bidirectional reflectance distribution function degradation in geostationary orbit

open access: yesEuropean Journal of Remote Sensing, 2020
The advanced geosynchronous radiation imager (AGRI) is a geostationary sensor whose reflective solar band is calibrated by a solar diffuser (SD). The SD bidirectional reflectance distribution function (BRDF) degrades over time in the space environment ...

Design, characterization, and fabrication of solar-retroreflective cool-wall materials [PDF]

open access: yes, 2020
Raising urban albedo increases the fraction of incident sunlight returned to outer space, cooling cities and their buildings. We evaluated the angular distribution of solar radiation incident on exterior walls in 17 U S.

Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared [PDF]

open access: yes, 2014
Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of TNOs smaller than ~1000km in diameter at the typical temperature in this region of the solar system, whereas the same models show

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.
