Since the typical solar panel isn’t portable, researchers have developed tiny solar cells that can be folded up for transportation, incorporated into clothing, or easily used in electronics. One example of this would be placing a mini-solar panel on a backpack that can then charge your devices while you walk. And since the cells are durable, they’ll last longer, making the cost of power cheaper. Keep a look out for tiny solar cells, they may soon be powering gadgets around you using sunlight only.
