New Solar Cell is the Size of a Lowercase Letter
The solar cells, about the size of a 12-point font letter ‘o,’ are being tested to eventually power microscopic machines, such as those used to test chemical leaks in the air.
The researchers at the University of South Florida say these are some of the smallest solar cells ever, with twenty aligning to form one panel at just one inch. Typical single cells are around two inches across on their own, and then form the large silicon panels we see on rooftops.
