New class of nanoparticle brings cheaper, lighter solar cells outdoors
Date:6/9/2014

TORONTO, ON Think those flat, glassy solar panels on your neighbour's roof are the pinnacle of solar technology? Think again.

Researchers in the University of Toronto's Edward S. Rogers Sr. Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that outshines the current state of the art employing this new class of technology.

This new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots, could lead to cheaper and more flexible solar cells, as well as better gas sensors, infrared lasers, infrared light emitting diodes and more. The work, led by post-doctoral researcher Zhijun Ning and Professor Ted Sargent, was published this week in Nature Materials.

Collecting sunlight using these tiny colloidal quantum dots depends on two types of semiconductors: n-type, which are rich in electrons; and p-type, which are poor in electrons. The problem? When exposed to the air, n-type materials bind to oxygen atoms, give up their electrons, and turn into p-type. Ning and colleagues modelled and demonstrated a new colloidal quantum dot n-type material that does not bind oxygen when exposed to air.

Maintaining stable n- and p-type layers simultaneously not only boosts the efficiency of light absorption, it opens up a world of new optoelectronic devices that capitalize on the best properties of both light and electricity. For the average person, this means more sophisticated weather satellites, remote controllers, satellite communication, or pollution detectors.

"This is a material innovation, that's the first part, and with this new material we can build new device structures," said Ning. "Iodide is almost a perfect ligand for these quantum solar cells with both high efficiency and air stabilityno one has shown that before."

Ning's new hybrid n- and p-type material achieved solar power conversion efficiency up to eight per
