Tiny High-Performance Solar Cells Turn Power Generation Sideways

University of Wisconsin-Madison engineers have created high-performance, micro-scale solar cells that outshine comparable devices in key performance measures. The miniature solar panels could power myriad personal devices — wearable medical sensors, smartwatches, even autofocusing contact lenses. Large, rooftop photovoltaic arrays generate electricity from charges moving vertically. The new, small cells, described in the journal Advanced […]
