Political Candidates Who Fight Climate Change Stand to Benefit in Election

Nearly 52% of Floridians favor candidates who reduce climate impacts. About 68% believe the state should take more action on climate issues and and 67% feel the federal government should as well. Notably, 88% acknowledge climate change is occurring. About 75% of respondents advocate for a diversified energy mix to include more electricity produced by renewable sources. Nearly 73% of respondents worry about home energy expenses and nearly 58% are concerned about being able to afford and maintain homeowners’ insurance due to climate change.

Multi-step photovoltaic power forecasting using transformer and recurrent neural networks

Abstract Affordable and clean energy is an important UN sustainable development goal. Solar energy is more difficult to control than fossil fuels, highlighting the need for accurate solar power forecasts. This study develops three variants of the transformer networks, called…

NUS researchers invent new triple-junction tandem solar cells with world-record efficiency

Scientists from the National University of Singapore (NUS) have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing triple-junction perovskite/Si tandem solar cell thus far. To achieve this, the team engineered a new cyanate-integrated perovskite solar cell that is stable and energy efficient.

Photo battery achieves competitive voltage

Networked intelligent devices and sensors can improve the energy efficiency of consumer products and buildings by monitoring their consumption in real time. Miniature devices like these being developed under the concept of the Internet of Things require energy sources that are as compact as possible in order to function autonomously.

Microdroplets, macro results: Beckman researchers pursue Energy Earthshots

Researchers at the Beckman Institute will conduct electrochemical reactions in microdroplets to produce clean hydrogen, sequester carbon dioxide, and store renewable energies like wind and solar inexpensively and sustainably. Their project, called DROPLETS, received $4.5 million from the U.S. Department of Energy’s Office of Science through its Energy Earthshots Initiative.

Chemists Unravel Reaction Mechanism for Clean Energy Catalyst

Chemists at the University of Kansas and Brookhaven National Laboratory have unraveled the entire reaction mechanism for a key class of water-splitting catalysts. Their work could help pure hydrogen be produced from renewable energy sources such as solar power.

GW Expert Available: Lawmakers vote to repeal President Biden’s suspension of solar tariffs

On Wednesday, Senate lawmakers voted to overturn President Joe Biden’s two-year suspension of tariffs on solar imports from countries in Southeast Asia, according to The Hill. The measure has already been approved by the House. The White House has said President Biden…

Nanoparticles Self-Assemble to Harvest Solar Energy

In APL Photonics, researchers design a solar harvester with enhanced energy conversion capabilities. The device employs a quasiperiodic nanoscale pattern, meaning most of it is an alternating and consistent pattern, while the remaining portion contains random defects that do not affect its performance. The fabrication process makes use of self-assembling nanoparticles, which form an organized material structure based on their interactions with nearby particles without any external instructions. Thermal energy harvested by the device can be transformed to electricity using thermoelectric materials.

Harnessing Plant Molecules to Harvest Solar Energy

ROCKVILLE, MD – Our current solar panels aren’t very efficient; they are only able to convert up to about 20 percent of the sun’s energy into electricity. As a result, to generate a lot of electricity, the panels require a lot of space—sometimes leading forests to be cut down or farms to be replaced by solar.

Research Reveals Thermal Instability of Solar Cells but Offers a Bright Path Forward

A new type of solar technology has seemed promising in recent years. Halide perovskite solar cells are both high performing and low cost for producing electrical energy – two necessary ingredients for any successful solar technology of the future. But new solar cell materials should also match the stability of silicon-based solar cells, which boast more than 25 years of reliability.

Producing ‘green’ energy — literally — from living plant ‘bio-solar cells’

By collecting electrons naturally transported within plant cells, scientists can generate electricity. Now, researchers reporting in ACS Applied Materials & Interfaces have, for the first time, used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

Jenny Nelson named Fred Kavli Distinguished Lecturer in Materials Science at 2022 MRS Fall Meeting & Exhibit

WARRENDALE, PA—The Materials Research Society (MRS) announced that Jenny Nelson, Imperial College London, has been selected for the Fred Kavli Distinguished Lectureship in Materials Science for the 2022 MRS Fall Meeting & Exhibit in Boston, Massachusetts. Nelson was selected by the 2022 MRS Fall Meeting Chairs.

Climate Change Consensus Endures in Florida

Seven sequenced surveys since October 2019 paint a comprehensive picture of Floridians’ climate resilience attitudes during a period of particularly dynamic political, economic and environmental events. Climate change has emerged as an abiding and cross-cutting issue in Florida.

Casting Shadows on Solar Cells Connected in Series

Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing photovoltaic technology. In the Journal of Renewable and Sustainable Energy, researchers explore how different shade conditions impact performance of single solar cells and two-cell systems connected in series and parallel. They found that the decrease in output current of a single cell or two cells connected in parallel was nearly identical to the ratio of shade to sunlight. However, for two cells running in series, there was excess power loss.

A lead-free solar material developed by Berkeley Lab scientists offers a simpler and more sustainable approach to solar cell manufacturing. The advance could also benefit halide perovskites, a promising solar technology that requires much less energy to manufacture than silicon.

Excitons Need Space to Separate: Free Carrier Production in Organic Solar Cells

New investigations have produced a simpler model to elegantly explain previously observed behaviors for free carrier generation in organic solar cells. The model relies on well-established scientific descriptors, Marcus theory and entropy. Previous descriptions proposed new physical phenomena, but a new, simplified model provides a unified platform for understanding processes in both solution and solid-phase systems for organic photochemical conversion.
