Glimpse of the Future
Take a Look Through the Clear Solar Panel of the Future
Researchers made a novel tweak to the burgeoning technology
Every week, Future Human’s Glimpse of the Future brings you an image of the science being deployed to solve the world’s pressing problems.
If I asked you to picture solar panels, you’d likely imagine clunky blue or black rectangles arranged on a sloping rooftop or arrayed in neat rows over an open field. These panels hold plenty of promise for providing humans with clean, renewable energy, but they’re not exactly versatile. You can’t just stick huge black panels anywhere.
That’s why, for years, scientists have been trying to make these panels transparent. Doing so would turn a range of surfaces — car windows, skyscraper walls, even phone screens — into potential clean energy generators. They’ve already seen some success: In 2020, for example, researchers at the University of Michigan made a semitransparent panel with 8% power conversion efficiency — a new record. Efficiency remains an obstacle, as do durability, cost, and transparency.
Researchers in Korea, Vietnam, and India recently took a stab at the transparent solar cell problem, publishing their work this week in the Journal of Power Sources. Their cell…
