Researchers at the University of Michigan have developed solar cells that are lighter than ever before, modeled after “kirigami,” the ancient Japanese art of paper cutting.
A team of engineers and an artist developed an array of small solar cells that can tilt within a larger panel, keeping their surfaces more perpendicular to the sun’s rays.
“The beauty of our design is, from the standpoint of the person who’s putting this panel up, nothing would really change,” said Max Shtein, associate professor of materials science and engineering. “But inside, it would be doing something remarkable on a tiny scale: the solar cell would split into tiny segments that would follow the position of the sun in unison.”
