In fact, I’m willing to bet that ultra thin and flexible solar cells that can be attached to virtually any surface will be the future. Which is why breakthroughs in this area are so important. And now a team of South Korea scientists has successfully created a super thin solar cell, which is so flexible it can be wrapped around a pencil without causing damage or too much strain to it.
