Key Highlights
•
Researchers have created carbon-based perovskite solar cells that reach a record 19.81% efficiency by adding aminothiophenol molecules to fix defects between the layers, making the cells more stable and better at capturing sunlight. This work makes inexpensive, all-inorganic solar cells much more practical for real-world use, as the improved design maintains over 90% of its performance after 1,000 hours in air.

A new type of flow battery called a thermally regenerative flow battery (TRFB) is being developed to capture low-grade waste heat, but its power is limited because the chemical reactions on each side of the battery don’t match up well. This study introduces a method to balance these reactions, which could significantly boost the battery’s power output and make it a more viable technology for turning waste heat into electricity.

A study in India used gravity and magnetic measurements to map the hidden rock structures deep below the Taptapani hot spring, revealing that thermal water flows up from over a mile underground along a fault line between two different rock types. This shows how geophysical surveys can pinpoint the best locations for geothermal energy projects, making it easier to tap into the Earth’s natural heat.
