Back-contact perovskite solar cells (BC-PSCs) represent a promising new alternative design to conventional solar cells, offering improved light absorption and higher power conversion efficiency. However, for addressing interfacial defects and recombination losses in BC-PSCs, advanced interface engineering techniques are required. Now, researchers have developed a novel bilayer tin oxide electron transport layer for BC-PSCs, which reduces recombination losses, promotes efficient charge transfer, and improves power conversion efficiency.

Sodium-ion batteries (SIBs) are emerging as a sustainable alternative to lithium-ion batteries, thanks to sodium’s abundance and low cost, but their true charging speed remains uncertain due to testing limitations. In a recent study, researchers used the diluted electrode method to shed light on hard carbon’s intrinsic fast-charging performance. Their measurements show that sodium inserts into hard carbon faster than lithium and that nanopore filling governs the overall rate, offering guidance for designing better SIBs.

From work meetings to first dates, it’s essential to adjust our behavior for success. In certain situations, it can even be a matter of life or death. So how do we switch our behavior when situations change? Published in Nature Communications, neuroscientists from the Okinawa Institute of Science and Technology (OIST) describe the neural basis of behavioral flexibility in mice, with insights which may help us understand a wide variety of diseases and disorders, from addiction to obsessive compulsive disorder (OCD) to Parkinson’s disease. 

A research team at Duke University has developed a new AI framework that can uncover simple, understandable rules that govern some of the most complex dynamics found in nature and technology. The research is part of a long-term mission in Chen’s General Robotics Lab, where the team aims to develop “machine scientists” to assist automatic scientific discovery.

Carbon trading revenues could exceed $40 billion annually by 2050 whilst helping the Philippines achieve net-zero emissions in its power sector, according to new research from the University of Surrey.  

In the International Journal of Extreme Manufacturing, researchers explore how extreme manufacturing helps brain implants record thousands of neurons for years with minimal impact on the brain.
