#ICYMI - Scientists have developed a #solar cell thinner than a coat of paint

Scientists at South Korea’s Gwangju Institute of Science and Technology have just developed a solar panel so thin it can be wrapped around a pencil. At just a micrometre wide, the PV cells are thinner than a single human hair or a coat of paint, which both measure up at around 100 micrometres . The slimmest solar cells currently available are still three to four times thicker than their newly-invented counterpart. Professor Jongho Lee, an engineer at the Gwangju Institute, said his team’s panels were “less fragile under bending, but perform similarly or even slightly better” than panels with a width of 3.5 micrometres. When the scientists tested the efficiency of the tiny panels, it was found that they are capable of converting sunligh t to electricity at a rate comparable to thicker photovoltaics. The researchers ‘stamped’ the cells , made from the semiconductor gallium a...
