Breakthrough in solar cell tech paves the way for cheaper access to the sun’s power

Two scientists from the University of Toronto have figured out a way to create cheaper, lighter and more flexible solar cells, CNET reports, which could allow more users in the future to harness energy directly from the sun for different purposes. Post doctoral researcher Zhijun Ning and Professor Ted Sargent have developed a “new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots” that can be used to make better and cheaper solar cells, better gas sensors, infrared lasers, infrared light emitting diodes, and other devices. What the two scientists managed to do is to prevent one of the semiconductors used in quantum dots to degrade when exposed to oxygen, thus improving efficiency of light absorption. Most importantly, the
