Scientists have developed solar cells 100 times thinner than a human hair
Solar power is totally peaking right now, smashing through cost barriers that previously held the technology back, to the extent that in some parts of the world, surplus energy from sunlight is being given away for free.
But if we’re ever going to unlock the true potential of solar, we need to think beyond today’s large rooftop solar panels, and examine what smaller, lightweight, and even wearable solar cells could do for us.
“Our photovoltaic is about 1 micrometre thick,” said engineer Jongho Lee from the Gwangju Institute of Science and Technology.
That makes it much, much thinner than a human hair – which range from to 10 to 200 micrometres in width – whereas standard photovoltaic cells can be hundreds of times thicker.
