Solar energy for sensor nodes

Tiny solar cells applied directly to a silicon chip are a potential way of efficiently and reliably powering wireless sensor networks in the future. Above all, this would simplify large-scale applications, for instance in ...

Plastic solar cells' new design promises bright future

Energy consumption is growing rapidly in the 21st century, with rising energy costs and sustainability issues greatly impacting the quality of human life. Harvesting energy directly from sunlight to generate electricity using ...

Auto lubricant could rev up medical imaging

Engineers at the University of California, Berkeley, have built a device that could speed up medical imaging without breaking the bank. The key ingredient? An engine lubricant called molybdenum disulfide, or MoS2, which has ...

Disorder can improve the performance of plastic solar cells

Scientists have spent decades trying to build flexible plastic solar cells efficient enough to compete with conventional cells made of silicon. To boost performance, research groups have tried creating new plastic materials ...

The best of two worlds: Solar hydrogen production breakthrough

Using a simple solar cell and a photo anode made of a metal oxide, HZB and TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the ...
