Solar UV-B irradiance and total ozone in Italy: Fluctuations and trends

open access: yes, 2000
Solar UV irradiance spectra (290-325 nm) together with daily total ozone column observations have been collected since 1992 by means of Brewer spectrophotometers at two Italian stations (Rome and Ispra).

Redefining Crystalline Silicon: Unlocking New Horizons in Transparent and Flexible Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
Crystalline silicon is presented as a platform for transparent and flexible photovoltaics. This review article outlines design principles for optical strategies to fabricate transparent silicon solar cells, mechanical strategies that mitigate silicon brittleness, and emerging concepts such as singlet‐fission spectral conversion and tandem architectures,

Prediction of total solar irradiance on tilted greenhouse surfaces

open access: yes, 2017
Solar radiation is the driving force for the surface energy balance in buildings such as greenhouses.  The greenhouses are generally tilted towards the sun in order to maximize the solar irradiance on the surfaces.

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

open access: yesAdvanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

Analysis of the Long‐Term Stability of TSI Instruments Using Allan Deviation and the Generation of a New TSI Composite

open access: yesEarth and Space Science
The dominant external forcing to Earth's climate system is solar radiation, referred to as the solar spectral irradiance (SSI) and the total solar irradiance (TSI), which is the integral of SSI over all wavelengths.

Thermally Stable Organic Synaptic Transistors Using a High‐Tg Polymer Electret

open access: yesAdvanced Intelligent Systems, EarlyView.
A high–glass‐transition‐temperature cyclic olefin copolymer (COC) electret enables thermally stable organic synaptic transistors for neuromorphic operation in harsh environments. UV–ozone treatment increases the trap density in COC, providing robust multilevel conductance and key synaptic functions (excitatory postsynaptic current/ inhibitory ...

On the variation of the Nimbus 7 total solar irradiance

open access: yes, 1992
For the interval December 1978 to April 1991, the value of the mean total solar irradiance, as measured by the Nimbus-7 Earth Radiation Budget Experiment channel 10C, was 1,372.02 Wm(exp -2), having a standard deviation of 0.65 Wm(exp -2), a coefficient ...
