Researchers Harness Black Metal to Turbocharge Solar Power

gizmodo.com Gayoung Lee 2025-11-21 20:00:39

Several years ago, an optics expert developed a technique for turning shiny metals pitch black. The trick resulted in a material perfectly suited for absorbing sunlight—so much so that generators built with it produced 15 times more power than comparable devices. The team used black metal to develop a new design for solar thermoelectric generators. Known as STEGs, they can convert various types of thermal energy into electricity. However, technological limitations significantly curbed their pot

Elements of System Design System design is often taught through domain-specific solutions specific to particular domains, such as databases, operating systems, or computer architecture, each with its own methods and vocabulary. While this diversity is a strength, it can obscure cross-cutting principles that recur across domains.
