Home > Press > Tiny solar cells built to power microscopic machines: New technology described in inaugural issue of Journal of Renewable and Sustainable Energy

Abstract:
Some of the tiniest solar cells ever built have been successfully tested as a power source for even tinier microscopic machines. An article in the inaugural issue of the Journal of Renewable and Sustainable Energy (JRSE), published by the American Institute of Physics (AIP), describes an inch-long array of 20 of these cells -- each one about a quarter the size of a lowercase "o" in a standard 12-point font.

Tiny solar cells built to power microscopic machines: New technology described in inaugural issue of Journal of Renewable and Sustainable Energy

COLLEGE PARK, MD | Posted on November 6th, 2008

The cells were made of an organic polymer and were joined together in an experiment aimed at proving their ability to power tiny devices that can be used to detect chemical leaks and for other applications, says Xiaomei Jiang, who led the research at the University of South Florida.

Traditional solar cells, such as the commercial type installed on rooftops, use a brittle backing made of silicon, the same sort of material upon which computer chips are built. By contrast, organic solar cells rely upon a polymer that has the same electrical properties of silicon wafers but can be dissolved and printed onto flexible material.

"I think these materials have a lot more potential than traditional silicon," says Jiang. "They could be sprayed on any surface that is exposed to sunlight -- a uniform, a car, a house."

Jiang and her colleagues fabricated their array of 20 tiny solar cells as a power source for running a microscopic sensor for detecting dangerous chemicals and toxins. The detector, known as a microeletromechanical system (MEMS) device, is built with carbon nanotubes and has already been tested using ordinary DC power supplied by batteries. When fully powered and hooked into a circuit, the carbon nanotubes can sensitively detect particular chemicals by measuring the electrical changes that occur when chemicals enter the tubes. The type of chemical can be distinguished by the exact change in the electrical signal.

The device needs a 15-volt power source to work, so far and Jiang's solar cell array can provide about half of that -- up to 7.8 volts in their laboratory tests. The next step, she says, is to optimize the device to increase the voltage and then combine the miniature solar array to the carbon nanotube chemical sensors. Jiang estimates they will be able to demonstrate this level of power with their next generation solar array by the end of the year.

The article "Fabrication of organic solar array for applications in microelectromechanical systems" by Xiaomei Jiang will be published by The Journal of Renewable and Sustainable Energy on November 6, 2008.

NOTE TO EDITORS: Dr. Xiaomei Jiang was born in Chongqing, a city in east Sichuan province, and she is a graduate of Sichuan University in Chengdu.
