🔬 Tin-based solar breakthrough keeps electrons hot way longer

Dutch scientists discovered that tin-based perovskite materials keep hot electrons energized for 1,000 times longer than expected. This research was conducted by scientists at the University of Groningen in the Netherlands. The study, published in ACS Energy Letters, highlights that the hot phonon bottleneck and Burstein–Moss effect work together to slow cooling from picoseconds to nanoseconds. This addresses a major solar energy challenge where excess electron energy is usually lost as heat. These findings could boost hot-carrier solar cells, improving solar conversion efficiency moving forward. 🔋

🦟 16yo student's malaria model wins $50k

Sixteen-year-old Rajarshi Mandal developed a mathematical model to optimize mosquito net distribution for malaria prevention. He is a rising junior from Lexington, Massachusetts, who built the ordinary differential equation simulation. His optimized allocation prevented twice as many infections as standard population-based methods using the same supply. This suggests better allocation, not just more nets, can boost public health impact. Mandal received a $50,000 Davidson Fellows Scholarship for his innovative research.
