Machine Learning‐Based Denoising of Surface Solar Irradiance Simulated With Monte Carlo Ray Tracing

Journal of Geophysical Research: Machine Learning and Computation
Simulating radiative transfer in the atmosphere with Monte Carlo ray tracing provides realistic surface irradiance in cloud‐resolving models. However, Monte Carlo methods are computationally expensive because large sampling budgets are required to obtain

Validation of the SARAH-E Satellite-Based Surface Solar Radiation Estimates over India

Remote Sensing, 2018
We evaluate the accuracy of the satellite-based surface solar radiation dataset called Surface Solar Radiation Data Set - Heliosat (SARAH-E) against in situ measurements over a variety of sites in India between 1999 and 2014.

Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3

Angewandte Chemie, EarlyView.
This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

Solar irradiance measurements

Living Reviews in Solar Physics
The Sun provides nearly all the energy powering the Earth’s climate system, far exceeding all other energy sources combined. The incident radiant energy, the “total solar irradiance,” has been measured by an uninterrupted series of temporally overlapping

The impact of a future solar minimum on climate change projections in the Northern Hemisphere

Environmental Research Letters, 2016
Solar variability represents a source of uncertainty in the future forcings used in climate model simulations. Current knowledge indicates that a descent of solar activity into an extended minimum state is a possible scenario.

Computation of Irradiance Distribution Near the Lunar South Pole and Data Validation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The lunar south pole has emerged as a focal point in deep space research in recent years and irradiance computation in this region, which elucidates spatial and temporal irradiance distribution, is vital for future exploration. The irradiance of both the

Model‐Based Bayesian Optimization for Organic Photovoltaics: Combining Bayesian Optimization With Physical Domain Knowledge

Advanced Energy Materials, EarlyView.
Integration of a physical solar cell model into Bayesian optimization is performed using the Knowledge Gradient acquisition function to balance exploration and exploitation. Experimental validation on the PTQ10:BTP‐eC9 material system and statistical validation on an OPV benchmark function show that the model‐based approach outperforms conventional ...

Efficient Flexible Monolithic Perovskite/CIGS Tandem Solar Cell by Using Two‐Step Hybrid Deposition Approach

Advanced Energy Materials, EarlyView.
Novel low‐temperature two‐step hybrid (co‐evaporation/solution) processing suppresses Zn‐induced perovskite degradation in monolithic perovskite/CIGS tandems. Lewis‐base additive engineering restores high crystallinity under the reduced‐temperature constraint.
