A tiny antenna could revolutionize solar panels

One of the big problem with current solar cells is that they are n’t capable to absorb infrared light — which accounts for around a third of the solar vigour that hits the planet . A new type of nanomaterial , a diminutive antenna , could figure out that problem and make our solar panels far more effective .

Solar panels have what ’s known as a “ bandgap ” , and any brightness level below that threshold frequency just pass direct through , not generating any king . But the Modern proficiency embeds tiny fiddling nanoantennae into the silicon of the panel , constructed of gold and titanium , and coated with tin oxide . When the infrared light hits the antenna , it generates a “ live electron , ” which jumps from the antenna into the silicon , creating a electric current .

The technology has the potential to go beyond just solar cells , and could potentially be used for photosensing , imagination , and light catching .
