X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Organic Solar Radiation Modification

Tellus
Despite the urgency to mitigate climate change, global greenhouse gas concentrations are still increasing, and even global emissions are still growing. Furthermore, the global sinks—both natural and technical—are not improving rapidly enough. Therefore, discussion and investigations to utilize solar radiation modification (SRM) have resurfaced ...

Evaluation of the cloudy sky solar UVA radiation exposures

, 2014
The influence of cloud on the solar UVA (320-400 nm) exposures over five minute periods on a horizontal plane has been investigated. The first approach used cloud modification factors that were evaluated using the influence of clouds on the global solar ...

Chlorination‐Enabled Oxygen Control and Dual‐Sulfur Source Aided Trap Passivation to Unlock 8.24% Efficient Sb2S3 Photovoltaic Devices

Advanced Functional Materials, EarlyView.
This work demonstrates a scalable, low‐temperature synthesis strategy that combines a thioacetamide (TA)‐based dual sulfur source with CdS chlorination, enabling the formation of high‐quality Sb2S3 with a reduced open‐circuit voltage loss, resulting in improved device efficiency.

UV Irradiance Enhancements by Scattering of Solar Radiation from Clouds

Atmosphere, 2015
Scattering of solar radiation by clouds can reduce or enhance solar global irradiance compared to cloudless-sky irradiance at the Earth’s surface. Cloud effects to global irradiance can be described by Cloud Modification Factors (CMF).

Solar Radiation Modification ‐ A “Silver Bullet” Climate Policy for Populist and Authoritarian Regimes? [PDF]

Global Policy, 2021
AbstractPopulist and authoritarian leaders are increasingly coming to power in large countries. They often have a climate sceptic approach and do away with mitigation policies when coming to power. Increasing impacts of extreme meteorological events linked to climate change could lead to a situation where the supporters of the populist leader or elites

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...
