By transfer printing instead of etching, the new method developed by Lee and his colleagues may be used to make very flexible photovoltaics with a smaller amount of materials. The thin cells can be integrated onto glasses frames or fabric and might power the next wave of wearable electronics.
Scientists have developed solar cells of 1 micrometer thick. That’s 100 times thinner than a human hair. Interesting isn’t it?
The solar cells at the second side are are almost as efficient as the cells in the front end. As a result, the panels can also utilize the light that is reflected by the surface of the water or the ground, which normally is lost.
By applying double-sided panels – working on water – the yield of solar power can be increased by 20% on average and expand the potential to generate solar energy even more.
So why not use both sides?
Double-sided solar panel
This week, Energy Research Centre (ECN) is demonstrating ‘floating double-sided solar panels on the ‘River IJ’ in Amsterdam. By also using the back of the solar panels, the reflected light from the surface of the water, can be catched to generate electric power. Read More
