Clean, sustainable energy solutions are essential to meet the ever-increasing energy demands of the human population. High efficiency solar cells are promising candidates to reduce carbon emissions and achieve carbon neutrality. In this regard, solution-processed copper indium gallium sulfur diselenide solar cells (CIGSSe) solar cells have generated significant interest owing to their excellent photovoltaic properties, such as high absorption of visible light, stability, and tunable bandgap. However, large scale, practical applications are limited by a two-fold challenge.

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.

A new study finds that the health benefits associated with wind power could more than quadruple if operators turned down output from the most polluting fossil-fuel-based power plants when energy from wind is available. However, compared to wealthier communities, disadvantaged communities would reap a smaller share of these benefits.

Tin sulfide (SnS) solar cells have shown immense promise in the rush to develop more environmentally friendly thin-film solar cells. Yet for years SnS solar cells have struggled to achieve a high conversion efficiency. To overcome this, a SnS interface exhibiting large band bending was necessary, something a research group has recently achieved.

Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.

Too much sun and too much heat can reduce the efficiency of photovoltaics. A solar farm with optimally spaced panels facing the correct direction could cool itself through convection using the surrounding wind. Researchers explored how to exploit the geometry of solar farms to enhance natural cooling mechanisms.

Wolf domestication occurred earlier than proposed until now, at least in western Europe. That possibility is raised by the results of the study of the humerus found in the Erralla cave (Gipuzkoa, Spain) in 1985.

The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.

The development of offshore wind energy is expanding globally, with the potential to be an important source of clean renewable energy. Yet offshore wind farms pose significant risks to seabirds and other marine wildlife. A new study outlines a framework for addressing the impacts of offshore wind farms on marine bird populations and highlights conservation strategies that could potentially more than offset those impacts.

Catalysts are of utmost relevance for the production of chemicals and energy storage with hydrogen. Researchers have now discovered that the formation of bubbles in the pores of a catalyst can be essential for its activity. Their findings help to optimize catalyst materials for reactions in which gases are formed from liquids -- and which play a central role in a future green hydrogen economy.
